A drug is any substance that changes how the body works once it gets inside the body. Some examples of drugs are nicotine, cocaine, steroids, marijuana, inhalants, and caffeine.
Different drugs have different effects on the body.
Others may speed up or slow down your system. People may use drugs for a number of reasons. Some take them out of curiosity to see what they feel like or because their friends are using them. Others take them to escape painful feelings and situations. Still others use drugs because they believe in myths- that a drug can make someone more confident, get more work done, feel less sad, improve their sex life, and have more fun.
