It is a synthetic drug usually sold as small tablets which come in a variety of colours and sizes. It is also available as powder and can be snorted or injected.
Ecstasy is a stimulant because it speeds up the functions of the central nervous system.
Effects can also depend on the quality and purity of the drug. The effects can start after about an hour and can last up to six hours, but may last as long as 32 hours. As ecstasy may cause the body's temperature to increase it is important to keep sipping water to prevent dehydration. Drinking water does not reduce the effects of ecstasy, it only prevents dehydration. Drinking too much water, however, may lead to serious health complications in some people.
