Cocaine is a powerful stimulant drug, commonly used recreationally and often referred to as coke. Cocaine can be snorted (the most common method of use), dissolved and injected intravenously, or smoked. There are many mental and physical side effects, though coke is most well-known for causing increased alertness, feelings of extreme happiness and hyperactivity. Physical symptoms include increased heart rate, profuse sweating, widened pupils, and increased body temperature and blood pressure. The effects of the drug will kick in almost simultaneously, and will usually not last more than an hour.
