Did you know that mental illnesses are brain disorders? There are differences in the structure and the way the brain functions in people with a mental illness. Researchers are still trying to understand the exact causes of mental illnesses, but it’s most likely that a combination of biological, genetic, environmental, and social factors play a part.
Research shows that brain development continues throughout the teen years and into a person’s twenties. Alcohol can alter this development, possibly affecting both the brain’s structure and how well it processes information. In addition, drinking during the teen years could interfere with normal adolescent brain development and change the brain in ways that raise the risk of developing an alcohol use disorder later in life.

Some people take prescription stimulants—without a prescription of their own—thinking the drugs will help them do better on a test. But there's no clear evidence that this works at all. Some research suggests that stimulants may actually dull creative thinking, though more studies are needed. teens.drugabuse.gov/blog/post/can-pill-improve-your-grades
Drinking alcohol is NOT a healthy way to cope with stress.

Some people who use MDMA (Ecstasy) might feel so alert and "hyper" that they could keep dancing at a club for hours, losing their sense of time and dangerously raising their body temperature. However, others can experience anxiety, agitation, faintness, sweating, or chills.
Marijuana is linked to problems in school. Marijuana’s negative effects on attention, memory, and learning can last for days and sometimes weeks—especially if you smoke often. One major study suggests it can even lower your IQ (a measurement of how smart you are).
Research tells us that most teens who misuse prescription drugs get them from friends or relatives and, to a lesser degree, from their own prescriptions. Is this a problem at your school? Ask our scientists about Adderall® and other commonly misused prescription drugs, such as Ritalin®, Xanax®, and Vicodin®.
People who smoke hookahs may be at risk for some of the same diseases as those who smoke cigarettes. These include lung cancer, oral cancer, and stomach cancer.
A menthol cigarette is still a cigarette—complete with all the chemicals and addiction risk that you'll find with any other tobacco product. Flavoring isn’t going to make it any safer. In fact, research shows that menthol cigarettes may be more addictive than nonmenthol cigarettes, which could make quitting even harder.
A lot of big changes happen to your brain when you’re a teen. Learn more about these changes: nimh.nih.gov/health/publications/the-teen-brain-still-under-construction/index.shtml#pub1

Heroin often contains toxic chemicals or additives that, when injected, can clog blood vessels leading to the lungs, liver, kidneys, or brain, causing permanent damage to vital organs.
Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increases the lungs' exposure to chemicals in the smoke, resulting in irritated lungs.
Stimulants such as cocaine cause the body’s blood vessels to narrow, constricting blood flow, which forces the heart to work harder to pump blood through the body. The heart might work so hard that it temporarily loses its natural rhythm. This is why people can die suddenly from a heart attack after using cocaine. teens.drugabuse.gov/drug-facts/stimulants
Alcohol misuse contributes to more than 200 diseases and injury-related health conditions, most notably, alcohol dependence, liver cirrhosis (loss of liver cells), various cancers, and injuries.
