Cocaine, also known as coke, is a strong stimulant most frequently used as a recreational drug. It is commonly snorted, inhaled as smoke, or dissolved and injected into a vein. Mental effects may include loss of contact with reality, an intense feeling of happiness, or agitation. Physical symptoms may include a fast heart rate, sweating, and large pupils. High doses can result in very high blood pressure or body temperature. Effects begin within seconds to minutes of use and last between five and ninety minutes. According to a 2007 United Nations report, cocaine is the second most widely used illicit substance in the world, after cannabis.
