The illicit use of drugs, including alcohol, by teenagers has been extensively studied and documented. It is not uncommon for teenagers to be involved in illicit drug use before exhibiting signs and symptoms of drug use. Unsuspecting parents may be unaware of drug use in their children. The authors also review the warning signs that a teen is using illicit drugs. The study provided new information about the risk stratifications of starting to use each drug of interest during adolescence.

This comparison is crucial: many studies have examined effects in adolescents only or in adults which were preexposed as adolescents, but such studies do not test for age specificity of the findings. The data and statistics on illicit drug and alcohol use and the consequences of such activities among teenagers are very frightening.

Teens are curious about the role their brain plays in alcohol and other drug use and addiction. In this second installment of "Teens Ask, FCD Prevention Works Answers," we asked for the help of students in some of our client schools in order to share what is on teens' minds when it comes to their brains. Want to catch up? Read the first installment. A: All addictive substances affect the reward pathway of the brain, through which teens are highly motivated.

Alcohol and other addictive drugs increase the number of reward-related chemicals in the brain. For instance, these substances flood the brain with a chemical called dopamine. This chemical flood can result in feelings of euphoria, relaxation, and relief from stress. Dopamine is an interesting chemical. Think of those times you've laughed until you've cried or lost your breath. That's dopamine at work.

But despite the fact that dopamine causes pleasure, its true job is not to make people feel good. Its real job is to drive a human to continue survival-related behavior, like sleeping and eating, and to encourage pro-social behavior, like forming bonds of friendship.

What makes addictive substances so risky is that their effects override the natural and healthy messages of the human brain. When alcohol and other drugs unnaturally increase dopamine in the teen brain, the using teen gets the message, "you don't need food or sleep or friendships as much as you need alcohol and other drugs.

What was once a healthily functioning survival mechanism of the reward pathway becomes a broken tool, damaged by repetitive substance use to create addiction. A: Brain cells, called neurons, are generally covered and protected with a fatty substance called myelin.

This myelin acts like an insulator, helping brain messages to travel from neuron to neuron, cell to cell, like electricity flowing through a series of telephone wires. Since teen brains are "in progress" in this way, teen brain cells send "louder" messages to one another than do adult brain cells, in much the same way that an identical song is broadcast much less attractively through a cheap speaker than it is through a highly-sophisticated sound system. It also means that when teens engage in risky behaviors like alcohol and other drug use, the reward pathway of the teen brain is highly sensitive to substances' effects.

A: Use of any addictive substance can be risky and comes with consequences. Long-term effects are not the only consequences! Instead, long-term effects happen after substance use has already caused plenty of other negative consequences for teens.

So when considering long-term consequences, remember that immediate and short-term consequences happen first, and can be equally devastating to a teen's life. It is important to intervene on teenage use of alcohol or other drugs as soon as you notice any risk or consequence.

If someone is suffering from the long-term physiological effects of alcohol or other drug use, he has likely continued with problem use in spite of humiliating experiences, relationship difficulties, and other health and social consequences. The long-term effects of marijuana are less well-known by many students and are the subject of continuing study in the scientific community.

Given the teen brain's unique vulnerability to substance use and addiction, it is extremely important that teens learn about the immediate, short-term, and long-term consequences of any substance use.

Adolescence may be challenging, but the teen brain is up to the task. A teen brain will flex, adapt, and grow in ways an adult brain cannot. The creative, engaging questions posed to FCD by our students are great examples! While teens are constantly preparing to meet the challenges of an adult world, and taking some risks during this time is natural.

Still, making too many risky decisions in the teen years while the may throw off the course of healthy brain development in ways that add an undue burden. Using substances as a response to peer pressure is one such risky decision.

This kind of use actually makes healthy personality development harder. Alleviating particularly intense negative emotions through over-stimulation of an already sensitive reward pathway is another risky choice. Learning to meet challenges, make healthy decisions, and have healthy fun can be exceptionally rewarding for growing teens. If teens take very good care of their brains during adolescence, their brains will continue to take very good care of them for the rest of their lives!

For forty years, FCD has worked worldwide to provide students and the adults who care for them with the knowledge, understanding and skills they need to make intelligent, healthy choices about alcohol, tobacco and other drug use.

The Hazelden Betty Ford Foundation is a force of healing and hope for individuals, families and communities affected by addiction to alcohol and other drugs. As the nation's leading nonprofit provider of comprehensive inpatient and outpatient treatment for adults and youth, the Foundation has 17 locations nationwide and collaborates with an expansive network throughout health care.

With a legacy that began in and includes the founding of the Betty Ford Center, the Foundation today also encompasses a graduate school of addiction studies, a publishing division, an addiction research center, recovery advocacy and thought leadership, professional and medical education programs, school-based prevention resources and a specialized program for children who grow up in families with addiction.

These are the students' insightful questions, and FCD's answers: Q: Once inside a teen's body, what do alcohol and other drugs actually do to the teen brain? Q: How do different substances act differently in the brain? A: Substances often fit into three categories: stimulants, depressants, and hallucinogens: Stimulants excite, or speed up, the brain and its functions.

Depressants inhibit, or slow down, the brain and body. Use of depressants can cause lowered energy, slowed breathing, slowed heart rate, and lower body temperature. Hallucinogens impair the brain and body's perception of reality. Use of hallucinogens can cause delusional thoughts, bizarre physical motions, and the experience of sights, sounds, tastes, and sensations that are not there.

Q: What's the difference between the teen and adult brain when it comes to alcohol and other drug use?

Q: Which substances are associated with long-term effects, and what are these effects? The long-term effects of alcohol misuse include: liver damage heart problems "beer belly" physical dependence on alcohol, producing other dangerous health conditions. Tobacco use also produces long-term effects, including: cancer emphysema reduced lung capacity, if smoked blackened or yellowed teeth early wrinkle formation The long-term effects of marijuana are less well-known by many students and are the subject of continuing study in the scientific community.

Some long-term effects of chronic marijuana use, however, are clear: impaired problem solving arrested emotional development difficulty with memory recall disruptive, chronic, and persistent lack of motivation increased risk of mental health disorders other than addiction, including: mood disorders e.

Cognitive deficits resulting from these alcohol and drug related neural insults have potentially harmful implications for subsequent academic, occupational, and social functioning extending into adulthood.

Therefore, neurocognitive sequelae from heavy drinking and drug use are important to elucidate. Adolescence marks a period of rapid development between childhood and adulthood involving complex social, biological, and psychological changes.

The interactions of these multidimensional factors have considerable implications for adolescent development. Included in these alterations are substantial changes in the efficiency and specialization of the adolescent brain, which is accomplished through synaptic refinement and myelination 8. Synaptic refinement involves reductions in gray matter by eliminating unnecessary neural connections 9. During adolescence, this synaptic pruning occurs primarily in the prefrontal and temporal cortex 10 and in subcortical structures such as the striatum, thalamus, and nucleus accumbens 11 , The adolescent brain also undergoes increased myelination, which allows for improved integrity of white matter fiber tracts and efficiency of neural conductivity 13 — Higher-order association areas appear to develop only after lower-order sensorimotor regions fully mature 17 , with frontal lobes being the final areas of the brain to complete development.

In conjunction with these numerous brain transformations, shifting social influences and peer group affiliation heavily impact adolescent behaviors 19 , This may place youth at a particularly heightened risk for initiating and continuing alcohol and drug use. The current literature suggests that heavy drinking during adolescence does have a subtle, but significant, deleterious effects on adolescent neurocognitive functioning.

Studies have found that adolescent heavy drinkers exhibit decrements in memory 24 , attention and speeded information processing 25 , 26 , and executive functioning 27 — In a study comparing alcohol dependent and healthy control adolescents, Brown et al. A similar degree of reduction was found on attentional and speeded information processing tasks in abstinent adolescent drinkers These findings are consistent with literature examining neurocognitive deficits in young heavy drinkers, which found similar decreases on attention and information processing, along with deficits in language competence and academic achievement Deficits in executive functioning, specifically in future planning, abstract reasoning strategies, and generation of new solutions to problems, have also been found While it has often been assumed that marijuana use is not linked to long-term cognitive deficits, recent data suggest that even after four weeks of monitored abstinence, adolescents who regularly smoke marijuana performed poorer on performance tests of learning, cognitive flexibility, visual scanning, error commission, and working memory Further, the number of lifetime marijuana use episodes was significantly related to overall poorer cognitive functioning, even after controlling for lifetime alcohol use.

We 7 prospectively examined neuropsychological functioning in 26 youths with no histories of alcohol or drug problems, and compared them to 47 youths with histories of heavy adolescent alcohol, marijuana, and stimulant use. Follow-up neuropsychological tests were given to the subjects seven different times across 8 years, on average between the ages of 16 to While there were no significant differences between users and non-users on neurocognitive test scores at the first time point, heavy drinkers performed worse on cognitive tasks at age 24 than light drinkers.

In particular, those who had a history of alcohol withdrawal symptoms e. Overall, heavy drinking during adolescence was linked to a reduction in keeping up with age expectations 7 , 25 , In summary, adolescence is characterized by dramatic increases in rates of substance use concurrent with ongoing neuromaturation.

While neuropsychological studies have shown that adolescent substance use is linked to poorer spatial, inhibitory, and learning and memory functioning, neuroimaging techniques may elucidate the neural mechanisms of these performance deficits. Advances in neuroimaging have made it feasible to closely characterize the brain structure and function of adolescent substance users and to pinpoint the circuitry and regions that may subserve the neuropsychological deficits observed in adolescent substance users.

Magnetic resonance imaging MRI was used to examine structural differences in the hippocampus, an area of the brain crucial to intact memory functioning. Hippocampal volume for adolescents with different substance use patterns. Adolescent users of alcohol, but not alcohol plus marijuana, showed significantly smaller left hippocampal volumes than demographically similar non-users Medina et al.

These findings support the hypothesis that heavy alcohol use in adolescence has an adverse influence on the hippocampus, potentially affecting subsequent memory performance. Additionally, marijuana, in combination with alcohol use, could have some neuroprotective effects, but further studies are warranted to examine this hypothesis.

An alternative explanation is that alcohol and marijuana use may create opposing mechanisms e. Microstructural hippocampal changes related to marijuana use may include increased glial proliferation and white matter density as well as reduced gray matter, resulting in relatively normal hippocampal volumes despite functional pathology. Alternatively, heavy adolescent marijuana use may subtly interfere with synaptic pruning processes, resulting in larger gray matter volumes, particularly in the left hippocampus 32 , During adolescence, the frontal lobe, an area of the brain associated with planning, inhibition, emotion regulation, and integration of novel stimuli, goes through extensive neuromaturation, increasing in efficiency and specialization.

Ventral prefrontal volume in adolescents with minimal and heavy drinking histories; ventral prefrontal region is highlight in white in the figure to the right. Interestingly, in our preliminary comparison of prefrontal cortex volumes of 16 marijuana-using and 16 control adolescents, few differences were observed. This was associated with poorer verbal memory, suggesting potentially interrupted synaptic pruning in female users. These findings also suggest that marijuana use during adolescence may disrupt gray matter pruning processes.

White matter maturation during adolescence through young adulthood is important for neuronal transmission between connecting brain regions. A recent study comparing adolescent marijuana users and matched controls indicated no significant differences in white matter volumes Further, marijuana use interacted with white matter volume to predict depression scores on the Beck Depression Inventory BDI Although between-group differences were not found in overall white matter volume, it seems plausible that marijuana use may cause or be linked to subtle alterations in white matter tracts that are responsible for mood regulation and depressive symptoms.

Chronic alcoholic adults show clear abnormalities in brain white matter volume as well as microstructural alterations in white matter tissue organization 40 — Typically, less white matter suggests dissipation of myelin-coated axons Diffusion tensor imaging DTI characterizes the integrity of water matter by examining the diffusion of water molecules in white matter tissue. Therefore, DTI provides information on the organization of localized white matter fiber tracts. Two commonly used scalar measurements are fractional anisotropy FA , which reflects white matter coherence by providing an estimate of the directionally dependent movement of water molecules, and mean diffusivity MD , an index of the overall displacement of water molecules.

In a preliminary analysis, we looked at the effects of both binge drinking alone and with combined marijuana use on white matter integrity Adolescent participants received DTI with whole brain coverage. Significant group differences were found in eight white matter regions, including frontal association fibers such as frontal-occipital and superior longitudinal fasciculi.

No significant MD differences were found in the 8 clusters identified by the FA analyses. Our findings suggest poorer white matter integrity in adolescents with histories of binge drinking than non-drinkers. However, teens with concomitant binge drinking and marijuana use showed a lesser degree of reduced fiber tract coherence than those engaging in binge drinking alone. These findings are largely consistent with our previous structural imaging studies that found small yet significant effects of marijuana use on adolescent brain structure and function 34 , 37 , and stronger associations between alcohol use and tissue status.

In a study that looked specifically at adolescents with alcohol use disorders, we found reduced white matter microstructural integrity compared to demographically matched youths without alcohol use disorders Significantly lower FA was found in the splenium of the corpus callosum, and trends for lower FA were also found in the rest of the corpus callosum, suggesting possible alcohol-related white matter alterations.

The callosal fibers are a massive collection of white matter tissue that connect the left and right hemispheres of the brain, and are important for efficient transfer of information. Microstructural changes in the corpus callosum may underlie neurocognitive changes associated with alcohol use during adolescent brain maturation. Notably, decreased white-matter integrity was significantly related to longer duration of heavy alcohol use, greater number of past alcohol withdrawal symptoms, and recent consumption of large amounts of alcohol.

Overall, our findings of reduced FA suggest possible myelination alterations in brain regions developing during adolescence, and underscore the impact of the effects of alcohol on white matter maturation during adolescence.

Future studies will follow these cohorts over the adolescent years to see if changes in substance use are followed by changes in indices of white matter quality. Understanding cerebral blood flow CBF is important since inadequate blood flow can damage brain tissue. CBF can also influence the blood oxygen dependent signal interpreted in functional magnetic resonance imaging fMRI. These findings may help clarify the metabolic changes behind differences in functional brain activity seen in adolescents with histories of alcohol misuse.

In addition to alterations in brain structure, recent findings have suggested decrements in brain functioning associated with adolescent substance use.

Functional magnetic resonance imaging fMRI investigates neural activity of the brain by measuring changes in blood oxygen level dependent BOLD signal 50 , which indicates areas of increased activation in response to a mental task or stimulus This technique is noninvasive and does not require injections or radioactive materials, making it a safe and appropriate technique for examining adolescent brain functioning.

Numerous studies involving adult alcoholics suggest neural disruption while executing cognitive tasks; however, it is unclear to what extent drinking must progress, and at what age, before abnormalities manifest. Our group 52 found that adolescents who drank heavily for one to two years showed abnormalities in brain response on cognitive tasks measuring spatial working memory SWM as compared to light drinkers. While both the heavy and light drinkers performed similarly on the task, heavy drinkers exhibited increased activation in the parietal lobe, with decreased activation in the occipital and cerebellar regions, compared to light drinkers In another study by our lab 53 , young adults who had engaged in four to five years of heavy drinking showed poorer performance on the same SWM task during fMRI, in addition to decreased activation in parietal and frontal regions.

Additional studies from our laboratory e. Although there were no differences in task performance between the marijuana users and controls, the marijuana users exhibited increased activation in parietal, temporal, and frontal including insula brain regions. The marijuana users also showed less activation in cerebellum and occipital cortices than controls.

Findings remained significant after controlling for alcohol and other drug use, and also suggest compensatory and possibly inefficient SWM-related neural response associated with marijuana use. Decrements in verbal encoding abilities have also been observed in binge drinking adolescents during fMRI tasks involving recall of learned word pairs This suggests less utilization of working memory systems during encoding for bingers compared to nondrinkers on tasks of encoding.

Further studies in our laboratory comparing verbal encoding abilities between adolescents reporting marijuana use and matched controls have found no differences on task performance. Although both groups performed similarly on the fMRI task, adolescent marijuana users have shown poorer performance on sensitive measures administered as part of an extensive neuropsychological test battery e. Taken together, changes in brain activation in adolescent marijuana users on a verbal encoding task may be indicative of less allocation of attentional resources toward encoding the novel material.

In addition to decrements in spatial working memory and verbal encoding, modestly decreased ability to inhibit behaviors has been found in binge drinking adolescents. These findings suggest that even infrequent exposure to large doses of alcohol may influence inhibitory processing.

As with all cross-sectional studies described, follow-up evaluations will help elucidate the temporal relationship between inhibition and alcohol use. We 59 also looked at response inhibition in marijuana users after 28 days of monitored abstinence, as compared to matched controls. Participants were excluded for any neurological problems or Axis I diagnoses other than cannabis abuse or dependence.

Differences remained even after controlling for lifetime and recent alcohol use. This suggests that marijuana users have increased brain processing effort during an inhibition task despite showing intact task performance, even after 28 days of abstinence. Such increased neural processing effort to achieve inhibition may predate the onset of regular use, or result from it. Adolescent response to alcohol advertising is of concern, as they are exposed to alcohol-related ads on a daily basis in many countries We 61 have observed that heavy drinking youth show greater brain activation while viewing alcohol advertisements than they do to non-alcohol beverage ads.

This substantially greater brain activation to alcoholic beverage pictures was observed throughout the brain, particularly in the prefrontal area, nucleus accumbens, hypothalamus, posterior cingulate, and temporal lobe, and was prominent in the left hemisphere, limbic, and visual cortices. This suggests that reward, visual attention limbic, appetitive, and episodic memory systems were preferentially invoked in response to alcohol ads relative to non-alcohol ads in heavy drinking teens.

These findings extend previous studies in adults, and link alcohol advertisement exposure in youth to activation in reward, desire, positive emotion, and episodic recall brain areas Relapse is a common clinical problem in individuals with substance dependence.

Previous studies have implicated a multifactorial process underlying relapse; however, the contribution of specific neural substrates had yet to be examined. The goals were to evaluate the neurobiology of decision-making dysfunction in stimulant dependent subjects, and to determine if functional imaging could be used as a tool to predict relapse.

All individuals underwent fMRI three to four weeks after cessation of substance use. Of the 40 subjects who were followed a median of days, 18 relapsed and 22 did not. The main outcome measure was BOLD activation during a simple two-choice prediction task.

During the prediction task, a house was presented, flanked by a person on its left and right. The participant decided on which side of the house a car would appear. Each trial was self-paced to maximize self-determined action, thus the subject determined the number of trials by the latency to select a response.

The screen provided the feedback whether the prediction was correct. The task captures the key elements of decision-making: the probability of an outcome associated with an option, the positive or negative consequence, and the magnitude of the consequence The fMRI activation patterns in right insular, posterior cingulate, and temporal cortex correctly predicted 20 out of 22 subjects who did not relapse, and 17 out of 18 subjects who did.

A Cox regression analysis revealed that the combination of right middle frontal gyrus, middle temporal gyrus, and posterior cingulate activation best predicted the time to relapse. In total, this is the first investigation to show that fMRI can be used to predict relapse in substance dependent individuals. The insular cortex may act through the interoceptive system to influence ability to differentiate between good versus poor choices, while the inferior parietal lobule may play a role in poor assessment of decision-making situations and subsequent reliance on habitual behavior.

Overall, substance dependent adults show brain patterns that can be used to predict whether and when relapse may occur. Overall, changes in brain functioning in adolescents differ by substance use pattern. Research has shown that heavy drinking during adolescence can lead to decreased performance on cognitive tasks of memory, attention, spatial skills, and executive functioning.

These behavioral ramifications of heavy alcohol use may emerge as a consequence of the reduced volume of important brain structures e. Studies have also shown that marijuana use during adolescence can result in decreases in cognitive functioning, particularly learning and sequencing scores. Corresponding marijuana-related changes in cognition may be related to increases in gray matter tissue volume, decreases in white matter microstructural integrity, and increases in neuronal activation during cognitive tasks.

In sum, we can reasonably rule out recent use as accounting for the observed differences between substance groups, given that participants in some studies have been abstinent one month or greater.

Substance using adolescents have been found to differ from non-users on neuropsychological performance, brain tissue volume, white matter integrity, and functional brain response. Longitudinal studies are essential to fully understand how alcohol and marijuana use affect adolescent neurodevelopment. The cross-sectional nature of the majority of studies examining adolescent neurocognitive functioning makes it difficult to determine the influence of alcohol and drug use on adolescent neurocognition.

Therefore, ongoing longitudinal neuroimaging studies are essential to ascertain the degree to which substance intake is linked temporally to adverse changes on indices of brain integrity, or whether neural abnormalities reflect pre-existing patterns. In cross-sectional or longitudinal work, several methodological features are critical to evaluate the potential influence of adolescent substance use on neurocognition. These issues pertain to ensuring participant compliance, accurately assessing potential confounds, and maximizing participant follow-up.

Adolescent compliance as a research participant can be maximized by attending to rapport, building trust, and ensuring privacy of self-report data to the extent that is ethical and feasible to the setting. For behavioral tasks within or outside of imaging, it is critical to ensure participants comprehend task instructions, are fully trained on fMRI tasks, and then are given reminders just prior to task administration. Motion during scan acquisition is detrimental to the quality of imaging data, and is often worse in younger adolescents than older teens or adults.

Accurately measuring and accounting for confounds frequently present in adolescent substance-using populations is essential for elucidating the true effect of substance use on adolescent neurocognitive functioning. Common confounds in this population include head injury, depression, ADHD, conduct disorder, prenatal exposure to neurotoxins, family history-related effects, and polysubstance involvement.

Accurately measuring abstinence is another important consideration in substance-related research protocols.

If abstinence is required for participation and compensation in a study, the dynamics of self-report could change. While biological data may help confirm self-report, these measures are imperfect and do not pinpoint the quantity of specific timing of substance intake 65 , Regarding abstinence from cannabis, obtaining serial quantitative THC metabolite levels, normalized to creatinine, is the best approach for guarding against new use episodes Tracking participants over time is a critical part of many clinical issues when interested in the degree to which a variable e.

Having a well-trained, friendly staff experienced with the population also helps retain participants and parents, and ensures that all participants fully understand the tasks and expectations during the study. Additionally, follow-up measures and procedures should be as similar as possible to baseline, except to mitigate learning and practice effects For imaging studies, field map unwarping of EPIs e. Finally, as technical problems are common, back up plans for each piece of equipment used in the neuroimaging session should be in place.

Current research suggests that substance use in adolescence leads to abnormalities in brain functioning, including poorer neurocognitive performance, white matter quality, changes in brain volume, and abnormal neuronal activation patterns.

A few questions still remain, such as whether heavy substance use during adolescence causes cognitive impairments and changes in neurodevelopment, if and when are critical periods of heightened vulnerability to such effects, and if observed abnormalities remit with reduced use. Harder parametric tasks that include conditions on which behavior does differ between groups would help us better understand the cognitive domains we have observed differences on.

Lastly, we need to better understand the biochemical changes that may mediate macrostructural, microstructural, and functional neuronal changes in response to substance use, such as cannabinoid receptor activity changes.

Multimodal approaches to neuroimaging may help us disentangle such questions e. Our group is currently conducting longitudinal studies of adolescent substance users as well as youth at risk for substance problems due to family history or early conduct disorder minimal use at the time of the first imaging session. Follow-up scan data, already underway, will elucidate if substance use during the follow-up interval predicts changes in brain functioning.

These investigations will ascertain if: 1 substance alcohol and marijuana, predominantly, given sample characteristics use during adolescence seems to cause detrimental changes in neurodevelopment, or if 2 substance use does not account for the differences, the previously observed differences would likely represent pre-existing markers of risk for heavy substance use during adolescence. The authors would like to express gratitude to all staff of the Adolescent Brain Imaging Project, and to the research participants and their families.

Brain Development, Teen Behavior and Preventing Drug Use

Seeking addiction treatment can feel overwhelming. We know the struggle, which is why we're uniquely qualified to help. Your call is confidential, and there's no pressure to commit to treatment until you're ready.

As a voluntary facility, we're here to help you heal -- on your terms. Our sole focus is getting you back to the healthy, sober life you deserve, and we are ready and waiting to answer your questions or concerns. Addictive drugs and substances are everywhere in our society.

Some have been around for decades or even centuries, while others have just cropped up in recent years. Treatment centers see teenage patients struggling with addiction to many different types of drugs. Take a look at some teen drug use facts:. Signs of drug use in teens refer to changes that an observer can spot and might act as a clue to confirm drug abuse.

Signs can fall into a few broad categories : paraphernalia, physical signs and psychological signs. Drug paraphernalia refers to items or tools used to ingest, hide or use different drugs. The different forms of paraphernalia vary depending on the drug and how the drug must be ingested to work.

Finding paraphernalia is one of the warning signs of teen drug use. Common pieces of paraphernalia by consumption method include:. If you are suspicious of a specific drug, look up symptoms of that specific drug. If you are suspicious but not sure which drug someone is abusing, general physical symptoms of drug abuse may include:.

Signs of withdrawal start within hours to days after they last used the drug. Withdrawal symptoms will depend on which type of drug your teen is using. You can also look for physical evidence of the drugs themselves, which are often left behind. Look for bits of marijuana green plant material , white powder, unknown pills, and other unfamiliar materials. Even if you find evidence, be careful not to assume the worst. However, keep each piece of evidence in mind to build the bigger picture.

Along with obvious signs, drugs can cause obvious changes in behavior. While teenage years bring about personality shifts, if you notice any combination of symptoms and suspect drug abuse might be a problem, make sure to address the problem.

While teen drug use is difficult to predict, research helps us identify the underlying causes of teen drug use. These factors can include:. To understand why teens use drugs , one much look at each teenager as an individual with needs, thoughts and feelings. The reason they use drugs is as varied as to why adults use them. Teens abuse the same drugs that adults do.

Drugs of abuse range from legal to illegal, and can be natural or unnatural. Be aware of all the common drugs used by teens so you can determine behavioral flags that indicate drug abuse. Illicit drugs and prescription substances are less common. How drugs are taken plays a role in the decision-making process around which drugs teens will take. Illicit drugs are made illegally and it is against the law to possess, distribute or take illicit drugs. Examples of teen party drugs include:.

Prescription medications are quickly taking a bigger piece of the pie when it comes to drug abuse. Teen prescription drug abuse is common as many of the drugs are easily accessible. Some examples of prescription drugs that are often misused include:. Teen drinking and underage drinking remain a common problem in our society. Alcohol may be difficult to shelter your child from, so make sure they know the health risks of alcohol like impaired judgment and alcohol poisoning. Teen alcohol abuse can be treated the same as any substance use disorder.

Treatment centers offer medical detox as well as drug and alcohol addiction treatment. Many facilities are specialized and exclusively treat teens. The effects of drug abuse on teens can be permanent and damaging to themselves, friends and family.

Risks can increase based on the drug of abuse, if other drugs are involved, and how long the abuse has been taking place. Young people may feel invincible and immune to the dangers of substance use; however, they can experience the effects and consequences the same as adults. Effects of teen drug use include:. The impact of drugs on the brain are different depending on the drug.

Other substances block pain signals and cause euphoria. Drug use can have an especially great effect on the brain during youth because the brain is growing and developing. When teens feel a drug high, they experience positive feelings that can seem to increase mood and happiness. Unfortunately, the positive effects are short-lived and come with health consequences. Long term effects of drugs on the brain are tolerance, dependence and addiction.

Brain damage from drugs can happen with heavy use even if your teen embraces sobriety later. Drug abuse and teen addiction are treatable. We now recognize addiction as a disease rather than a moral failing. Teen drug use is often acute or a short-term stress response. They may have a stressful personal life or may be curious and trying to fit in with a friend.

Drug addiction is a difficult medical condition to treat but, with the help of rehab professionals, you can help them recover. Thousands of clinics and specially-trained practitioners offer substance abuse treatment for teens battling drug abuse or addiction.

Treatment options for substance abuse implement therapy, counseling, medication and other proven tools designed to retrain an addict to live without drugs. In this case, it may be time to consider professional treatment. Doctors and treatment specialists have spent decades working on and perfecting their methodologies, and they can help teens struggling with addiction defeat their illness. Give your teen the best chance they have to overcome drug abuse problems.

A professional can help you assess the situation and determine any next steps to take and if teen drug rehab is necessary. If your child needs help, a professional will go over substance abuse treatment options with you and your child. Sources Indian Health Services. Accessed June 24, National Institute of Health.
