Stimulants are drugs that speed up the brain and body, so a person feels more awake, alert, and full of energy. They include ADHD medicines such as Adderall, illegal drugs such as cocaine and meth, and the caffeine in coffee. When a teen misuses them, the risks range from lost sleep to addiction and overdose.
At White River Academy, we work with families of boys ages 12 to 17 whose stimulant use has started to cause harm. Our stimulant addiction treatment for teens is long-term, live-in care in Delta, Utah. Knowing what stimulants are and how they act on a teen’s brain can help you spot a problem sooner.
What Are Stimulants and How Do They Work?

Stimulants increase activity in the central nervous system, which is the brain and spinal cord. This can make a person feel more awake and alert. Depending on the drug and dose, effects can also include a rise in heart rate, blood pressure, breathing rate, and body temperature.
Amphetamine, methylphenidate, and cocaine affect brain chemicals such as dopamine and norepinephrine, although they do so in different ways. Dopamine helps regulate reward, motivation, and movement. Norepinephrine helps regulate alertness and the body’s stress response. Caffeine and nicotine stimulate the nervous system through other mechanisms.
This rush of dopamine is part of how stimulants work, and it is also what makes misuse feel good. Over time, the brain starts to expect the drug, which helps explain how addictive Adderall can be when it is misused. The strength of the effects depends on the drug, the dose, how it is taken, and the person taking it.
Types of Stimulants
Stimulant drugs fall into three groups: prescription stimulants, illicit stimulants, and legal ones found in everyday products. They come in many forms, such as pills, powders, crystals, and vapes. Many are controlled substances, so federal law limits who can make, prescribe, and sell them. The table lists common examples and how the law treats each.
| Stimulant | Type | Federal Status | Medical Use or Where Found |
|---|---|---|---|
| Amphetamine (Adderall) | Prescription | Schedule II | ADHD and narcolepsy |
| Lisdexamfetamine (Vyvanse) | Prescription | Schedule II | ADHD, and binge eating disorder in adults |
| Methylphenidate (Concerta, Ritalin LA) | Prescription | Schedule II | ADHD (some other methylphenidate forms also treat narcolepsy) |
| Cocaine | Illicit | Schedule II | Local anesthesia for certain nasal procedures in adults |
| Methamphetamine (meth) | Illicit | Schedule II | Street meth is made illegally |
| MDMA (ecstasy, molly) | Illicit | Schedule I | No accepted medical use |
| Caffeine | Legal | Not controlled | Coffee, tea, soda and energy drinks |
| Nicotine | Tobacco sales restricted to adults 21 and older | Not controlled | Cigarettes and vapes |
Schedule II means a drug has a medical use. It also has a high risk of misuse and severe dependence. Most stimulants in this table have that label, and MDMA is in Schedule I. Other stimulants include man-made “bath salts” and caffeine pills sold over the counter.
Prescription Stimulant Medications
Prescription stimulant medications are the main ADHD medications that doctors use. ADHD is short for attention deficit hyperactivity disorder. It makes it hard for a child to focus, sit still, and think before he acts. Once doctors find the right dose, many kids have fewer ADHD symptoms.
Doctors use amphetamines like Adderall for ADHD and, in some formulations, narcolepsy, a sleep disorder. Methylphenidate products such as Concerta and Ritalin LA treat ADHD; some other methylphenidate formulations also treat narcolepsy. Vyvanse contains lisdexamfetamine and treats ADHD. How long a dose lasts depends on the product and formulation.
Taking prescribed stimulants exactly as directed is not misuse, and it is a standard way to treat ADHD. Side effects can include decreased appetite and poor sleep, and some kids take non-stimulants instead. Problems start when a teen takes extra pills, crushes them, or uses someone else’s prescription medications. Teens who take Adderall or Ritalin to stay up and cram are using what many students call study drugs.
Illicit and Legal Stimulants
Cocaine comes from the leaves of the coca plant, which grows in South America. Doctors can still use it as a local anesthetic, but the cocaine teens come across is sold illegally. Its high is strong but short, which can push a person to use again within a short period.
Methamphetamine is chemically similar to the amphetamine in Adderall. At a similar dose, though, more of it gets into the brain. Street meth is a strong illicit stimulant with a high risk of addiction. Even so, ADHD medicine taken as directed is not meth, and our post on how Adderall and meth differ explains why.
MDMA, also called ecstasy or molly, acts like both stimulants and hallucinogens, the Drug Enforcement Administration (DEA) says. Caffeine is often called the most used stimulant in the world. It is legal and found in coffee, tea, and soda. Nicotine in vapes and cigarettes is a stimulant too, and it is very addictive.
Why Teens Use Stimulants
Teen stimulant use often starts with a goal rather than a wish to get high. Some boys want more energy for sports or school, and others are curious or copying friends. Common reasons a teen may start taking stimulants include the ones below.
- Staying awake to study or finish work
- Boosting physical performance in sports
- Losing weight or cutting for a weight class
- Getting high at parties, often with alcohol or other recreational drugs
- Coping with stress, low mood, or untreated ADHD
National data show that misuse is not common, but it does happen. In the 2025 Monitoring the Future survey, nonmedical Adderall use stayed at 3 percent or less in 8th, 10th, and 12th grade. Past-year cocaine use among 12th graders rose from 0.9 percent in 2024 to 1.4 percent in 2025 [1]. Vaping nicotine was far more common, at 20 percent of 12th graders.
Stimulant Side Effects
Stimulant side effects depend on the drug, the dose, and how often a teen uses it. Some show up within minutes, while others build over months of use. Certain stimulants, such as meth and cocaine, tend to cause stronger effects than medicine taken as prescribed.
Short-Term Effects
In the short term, a teen taking stimulants may seem wired, chatty, or unable to sleep at night. These short-term effects are often the first ones parents notice at home.
- Increased alertness and extended wakefulness
- Decreased appetite and skipped meals
- Increased heart rate and higher blood pressure
- Faster breathing and a higher body temperature
- Anxiety, restlessness or a short temper
- Headache, sweating, or abdominal cramps
High doses raise the risk of overdose, which can cause a very high fever, an uneven heartbeat, or seizures. Physical exertion, like hard exercise in the heat, makes these risks worse. So does mixing stimulants with alcohol or other drugs.
Long-Term Effects
Repeated misuse changes how the brain works, and some effects last long after use stops. Over months of misuse, a teen may develop one or more of the long-term problems below.
- Tolerance, so he needs higher doses for the same effect
- Dependence and addiction
- Paranoia, hallucinations, or psychosis, which means losing touch with what is real
- Hostile or aggressive behavior
- Problems with memory and cognitive function
- Heart and blood vessel problems
When a teen stops after heavy use, he may crash. That crash, part of withdrawal, can bring deep fatigue, long sleep, strong hunger, depression, and agitation. Some teens have thoughts of suicide at this stage, so call or text 988 if you are worried about his safety.
Signs a Teen May Be Misusing Stimulants

Many signs look like normal teen moods, so look for several new changes at once. Common signs of stimulant abuse include little sleep, weight loss, fast talk, and bursts of energy that end in long crashes. You may also find pills missing at home, or notice money problems and new friends.
Signs also differ by drug, so a teen on cocaine may look different from one using meth or a friend’s Adderall. A doctor can test urine, saliva, or blood for stimulants, though each test finds only recent use.
Counterfeit and Contaminated Stimulants
A teen who buys a stimulant from a friend or online cannot know what is really in it. A pink powder sold as tusi, or “pink cocaine,” is often a mix of other drugs, such as ketamine and MDMA. Because the buyer cannot see what is inside, any street powder can contain a far more dangerous drug.
Fentanyl is a very strong opioid, and it has turned up in cocaine and other drugs sold on the street. A teen who expects only a stimulant may have no tolerance for it. Even a small amount can stop his breathing. In CDC data from 49 states and Washington, DC, 73 percent of stimulant-involved overdose deaths from January 2021 through June 2024 also involved opioids [2]. This does not mean every death involved an unknowingly contaminated drug.
Pills sold as Adderall outside a pharmacy can be pressed pills that copy real medicine. These fakes may hold meth or fentanyl, and they can look just like the real thing. So treat any pill that did not come from a pharmacy in his name as unknown.
Teen Stimulant Use in Utah
Utah’s 2025 Student Health and Risk Prevention (SHARP) survey asked 79,794 students in grades 6, 8, 10, and 12 about drug use. Among 8th, 10th, and 12th graders, 1.4 percent said they had ever misused a prescription stimulant [3]. In the past 30 days, 0.5 percent had done so, and the lifetime figure was 1.8 percent in 2023.
A low state rate does not mean stimulants are absent from your son’s school or friends. The 2025 report gives no figure for meth or cocaine use, so the number above covers prescription pills only.
Misuse vs. Dependence vs. Stimulant Use Disorder
Misuse, physical dependence, and addiction are related, but they are not the same thing. Clinicians diagnose stimulant use disorder using a pattern of symptoms and rate it as mild, moderate, or severe. The table shows examples a parent may notice; these are not inevitable stages that every teen passes through.
| Term | What It Means | What a Parent May Notice |
|---|---|---|
| Prescribed use | Taking his own medicine exactly as directed | A steady routine and no missing pills |
| Misuse | Extra doses, someone else’s pills, or use to get high | Pills running out early, late nights |
| Tolerance | The same dose no longer has the same effect | Taking more, or taking it more often |
| Dependence | The body has adjusted and reacts when the drug stops | Crashes, heavy sleep and low mood between uses |
| Stimulant use disorder | Use goes on despite harm, and attempts to stop fail | Cravings, broken promises, dropped interests |
Dependence can happen even with prescribed medicine. A teen with his own prescription should stop only with his doctor’s plan. A stimulant use disorder is different, because he keeps using even as it hurts his health and family. At that point, a full check by an addiction doctor is a good next step.
How Adolescent Stimulant Use Disorder Is Treated
For a teen with a stimulant use disorder, treatment is mostly therapy, not medicine. The National Institute on Drug Abuse notes that the Food and Drug Administration has not approved a medicine for cocaine use disorder [4]. Doctors may still use some drugs “off label,” and they treat any ADHD, depression, or anxiety he has.
Behavioral Therapies
In 2024, the American Society of Addiction Medicine and the American Academy of Addiction Psychiatry published a joint guideline [5]. It was based on a systematic review, and it calls contingency management the current standard of care. That method gives small rewards, such as vouchers, for drug-free tests, and it works best when added to other counseling.
For teens, the guideline also backs family therapy and cognitive behavioral therapy (CBT), which works on the thoughts behind what they do. It asks care teams to use models made for teens and young adults. Family members or other trusted adults should take part when it makes sense.
After heavy meth use, the crash can bring days of deep tiredness and low mood. Withdrawal from meth often brings strong cravings too. Medically supervised withdrawal happens before or alongside residential care, and we help families plan that step. Therapy then works on the habits, stress, and triggers that led to his use.
Levels of Care for Teens
Addiction treatment for teens comes in several levels, from weekly counseling to care around the clock. The right level depends on how severe his use is, his mental health, and the support he has at home. The table compares the main options.
| Level of Care | Where He Lives | Who It May Fit |
|---|---|---|
| Outpatient counseling | At home | Early misuse with strong support at home |
| Intensive outpatient (IOP) | At home, with treatment several days a week | Teens who need more structure than weekly visits |
| Partial hospitalization (PHP) | At home, with treatment most of the day | Teens who need daily care and are medically stable |
| Hospital or withdrawal unit | In the unit, with 24/7 medical care | Teens with dangerous symptoms or psychosis |
| Residential treatment | At the treatment center | Ongoing use after outpatient care, or co-occurring disorders |
We provide long-term residential treatment for teen boys in Delta, Utah, and we do not offer outpatient or hospital care. Our program fits families who need more structure than care at home can provide. If he needs another level of care, we can talk through the options with you.
What Are Stimulants? Frequently Asked Questions
What Are Some Common Stimulant Drugs?
Common stimulant drugs include ADHD medicines such as Adderall, Vyvanse, and Concerta. Cocaine and meth are usually encountered as illegal street drugs, though both have limited medical uses. MDMA also has stimulant effects. Caffeine and nicotine are common legal stimulants, and regular use of either can cause withdrawal when stopped.
What Is a Street Name for a Stimulant?
Street names for stimulants on the DEA’s list include speed, uppers, crank, ice, coke, snow, and Vitamin R. Slang changes often, so hearing one of these words proves little on its own. Still, it is a good reason to start a calm talk with your son and ask what he knows.
What Does Adderall Do to a Teenager?
Taken as prescribed for ADHD, Adderall can help a teen focus and control impulses. Side effects can include poor appetite and trouble sleeping. When misused, it can cause a racing heart, anxiety, and very little sleep. High doses or long-term misuse can lead to paranoia, dependence, and addiction.
Can a Teen Overdose on Stimulants?
Yes, and a stimulant overdose is an emergency. Signs can include chest pain, a very high body temperature, seizures, or signs of a heart attack or stroke. The risk rises with high doses and with alcohol or other drugs, and hidden fentanyl adds an opioid risk. Call 911 right away.
If you have questions about stimulants and your son, you do not have to sort them out alone. Our team can talk through what you have seen and whether residential care fits his needs. You can read about the first steps on our admissions page. Call our confidential admissions team.
