Drugs are chemicals that change the way a person's body works. You've probably heard that drugs are bad for you, but what does that mean and why are they bad?
If you've ever been sick and had to take medicine, you already know about one kind of drugs. Medicines are legal drugs, meaning doctors are allowed to prescribe them for patients, stores can sell them, and people are allowed to buy them. But it's not legal, or safe, for people to use these medicines any way they want or to buy them from people who are selling them illegally.
Cigarettes and alcohol are two other kinds of legal drugs. (In the United States, adults 18 and over can buy cigarettes and those 21 and over can buy alcohol.) But smoking and excessive drinking are not healthy for adults and off limits for kids.
When people talk about the "drug problem," they usually mean abusing legal drugs or using illegal drugs, such as marijuana, ecstasy, cocaine, LSD, crystal meth and heroine. (Marijuana is generally an illegal drug, but some states allow doctors to prescribe it to adults for certain illnesses).
Illegal drugs aren't good for anyone, but they are partic
ularly bad for a kid or teen whose body is still growing. Illegal drugs can damage the brain, heart, and other important organs. Cocaine, for instance, can cause a heart attack — even in a kid or teen.
While using drugs, a person is also less able to do well in school, sports, and other activities. It's often harder to think clearly and make good decisions. People can do dumb or dangerous things that could hurt themselves — or other people — when they use drugs.
Sometimes kids and teens try drugs to fit in with a group of friends. Or they might be curious or just bored. A person may use illegal drugs for many reasons, but often because they help the person escape from reality for a while. If a person is sad or upset, a drug can temporarily make the person feel better or forget about problems. But this escape lasts only until the drug wears off.
Drugs don't solve problems, of course. And using drugs often causes other
problems on top of the problems the person had in the first place. A person who uses drugs can become dependent on them, or addicted. This means that the person's body becomes so accustomed to having this drug that he or she can't function well without it.
Once a person is addicted, it's very hard to stop taking drugs. Stopping can cause withdrawal symptoms, such as vomiting (throwing up), sweating, and tremors (shaking). These sick feelings continue until the person's body gets adjusted to being drug free again.
