1.2 Types of drugs - 1. Get high Some drugs make you feel more alert and energetic. They increase your heart rate and blood pressure – e.g. cocaine, crack, ecstasy, speed, tobacco. 2. Calm down Some drugs slow you down. They can make you feel calm and sleepy – e.g. alcohol, cannabis, gases, glues and aerosols (also known as volatile substances), tranquillisers. 3. Trip out Some drugs affect your mind. They distort the way you see, hear, feel and smell things – e.g. cannabis, ketamine, LSD, magic mushrooms. 4. Get knocked out Some drugs block out physical and emotional pain – e.g. heroin. (www.dh.gov.uk)
