Drug

A drug is a substance that has an effect on the body or mind. Drugs have long been used as medicines to treat illness or injury, as a means of changing one's mood or perception, and as a means of obtaining religious or spiritual experiences.

Different societies have allowed or prohibited the social use of different drugs. The use of alcohol, nicotine and caffein is permitted in most Western countries. Alcohol is prohibited in many Islamic countries.

Conservatives, with typical hypocrisy, have long considered recreational drug use to be immoral, discussing the topic over a scotch and a cigarette, followed by a cup of coffee.
