1. This was the website that used to find out what drugs street children take. I found out that drugs are placed into categories. Stimulants are types of drugs that give a short, energetic effect. These are just recreational drugs. Drugs such as Ecstasy and Crack Cocaine are stimulants.
2. Depressents are drugs that give a relaxing and sensational feeling, as well as reducing the intensity of pain and of emotions such as fear, anger or anxiety. Examples are Morphine.
