Some teens believe drugs will help them think better, and be more popular. These days, drugs can be found everywhere. Many teens are tempted(诱惑) by the excitement or escape from reality that drugs seem to offer.

Drugs are chemicals that change the way our bodies work. When you put them into your body, drugs find their way in your blood and are taken to parts of your body, such as your brain.

The effects of drugs can be different depending on the kind of drug taken, how much is taken, how often it is used, how quickly it gets to the brain, and what other drugs or food are taken at the same time. Although drugs can make you feel good at first, they can finally do a lot of harm to the body.

There are many kinds of drugs available, and there are many reasons for trying them regularly. People take drugs just for pleasure they believe they can bring. Often it’s because someone told them that drugs would make them feel good or that they’d have a better time if they took them.

Many teens use drugs because they’re unhappy or think drugs will help them escape their problems. The truth is that drugs don’t solve problems—they simply hide feelings and problems. When a drug wears off, the feelings and problems remain, or became worse. Drugs can ruin every aspect of a person’s life.
