Glossary

You’ve heard people say “Just Say NO!” to drugs because they’re addictive and can hurt your health. But how much do you really know about drugs and other things that can mess with your mind and body?

The list below can help you understand what’s out there. It includes popular illegal drugs. But it also includes prescription medicines. That’s because they are okay only for the person who was given the prescription and only in the amount prescribed. The list also includes stuff that can seem pretty safe because they’re easy to get, like over-the-counter medicines, energy drinks, and household products like hairspray. The truth is, though, that these items can cause very serious problems if used in unhealthy ways. Keep reading to learn about how drugs can slam your health both now and down the road — long after any good feelings wear off.

Caffeine and “energy” drinks top

In reasonable amounts caffeine is safe for most people. But consuming a lot of caffeine can cause serious problems no matter what form it comes in, from extra espresso shots to caffeine pills (like NoDoz). And energy drinks that have become popular can pack a huge punch. In fact, some brands have as much caffeine as 5 cups of coffee! You’d never know it, though, because the labels don’t have to include that information.

Also called: Cat,Aall,Bout,Teaser,Tip

What it looks like: Energy drinks can look like soft drinks, but often have a lot more caffeine. They also can look like sports drinks such as Gatorade, but don’t help your body refuel in the same way.

What it can do to you: Caffeine can make you feel awake and full of energy, but when it wears off, your energy can come crashing down.

Some dangers of too much caffeine:

  • Nervousness
  • Feeling irritable
  • Trouble sleeping
  •  Fast heartbeat
  • Stomach problems
  • Withdrawal symptoms, like headache and dizziness

Caffeine drinks combined with alcohol can cause even bigger problems. You could be drunk and full of energy. That could get you into some very dangerous situations.

Club drugs top

These drugs are most often found at events like parties, dance clubs, raves, and concerts. They include date rape drugs, methamphetamine, ecstasy, and LSD. All of these drugs can possibly make you very sick. These drugs can have a big effect on your mind and can cause you to make poor decisions.

Cocaine/Crack top

Some users will need more of it with each time they get high.

  • Death

Date rape drugs top

Date rape drugs such as Rohypnol, GHB, and Ketamine can be used to sexually assault a person. The drugs often have no color, smell, or taste and are easily added to drinks without the victim’s knowledge. These drugs can cause a person to become physically helpless, so they are not able to protect themselves from being hurt. They can also cause the person to forget what happened while they were under the effect of the drug. They also can affect the body in different problematic ways, depending on the drug. In rare cases, and particularly when combined with alcohol, these drugs can cause death.

If you think you may have been the victim of a sexual attack, learn more and get help.

You can’t know how hallucinogens will affect your mood or your senses, which means you could wind up doing something dangerous or having an accident.

It also is linked to problems in school, in relationships, and in overall life satisfaction. If you have heard of “medical marijuana,” you may think that means it’s safe. It’s not. Although some states let doctors prescribe marijuana for patients with certain medical problems, the Food and Drug Administration has not approved it as a medication.

PCP has very unpredictable effects, but it often does not make people feel good. PCP is addictive, which means it is hard to stop taking it. People who abuse PCP for a long time may have memory loss and trouble speaking and thinking.

Prescription medicines top

Some people think using prescription medicines to get high is safer than using street drugs. But if you take someone else’s medicine — or take more of your own than the doctor says — you can get addicted or have very serious health problems.

One type of prescription medicine that people sometimes misuse is depressants. These medicines “depress,” or slow down, your brain and body. They include tranquilizers, sedatives, and sleeping pills that can calm your nerves and relax your muscles. These include Ativan, Valium, and Xanax, which are sometimes called by slang names like “candy” and “tranks.”

Another type of prescription medicine that is sometimes misused is stimulants. They can “stimulate” you, or make you feel very awake or happy. These include the ADHD medicines Ritalin, Concerta, and Adderall.

Other prescription medicines that are misused may be pain relievers, like codeine, which come as brand-name medicines like Vicodin, OxyContin, and Tylenol with codeine. They can make you feel happy or sleepy.

Prescription depressants, stimulants, and pain relievers all are addictive and can cause death, especially if taken at high doses or combined with other medications or drugs.  Also, depending on the medication, they may cause problems like changes in heartbeat, slowed breathing, seizures, anxiety, and a dangerously high body temperature.

Ritalin top

Also called: R-ball, Rits, Smart Drug, Vitamin R, West Coast

What it is: Ritalin is a prescription medicine used to treat attention-deficit hyperactivity disorder (ADHD). It can be swallowed, crushed, snorted, or injected. Another prescription medication, Concerta, is used in similar ways.

  • Severe confusion

What it looks like: Steroids are pills taken orally, injected into the muscle, or rubbed on the skin (gels or creams).

Girls sometimes use these steroids because they want to improve their athletic performance. They make girls start to develop male physical characteristics, like facial hair.

  • Irregular menstrual cycle (periods)
  • Aggression (acting violently)

Stimulants top

Stimulants can make you feel in a good mood, full of energy, and less hungry. They include the illegal drugs cocaine and crack. There also are prescription stimulants, like Ritalin that can be safe if used as directed but that are dangerous if misused. Ecstasy/MDMA is an illegal stimulant that tends to be found at parties or clubs. Methamphetamine is a very addictive stimulant that has some uses as a medicine but that is often made in dangerous labs.

Abuse of stimulants can cause a variety of health effects, depending on the drug. These include heart problems, anxiety, seizures, and paranoia.
