Ecstasy is often known as a club drug because it is primarily used at dance clubs, bars and raves. Ecstasy is usually sold in a pill form which often times contains cartoon-like images on them and come in a variety of colors. The contents in Ecstasy can vary depending on the person who is selling them, so you never know what you are going to get until it may be too late. Ecstasy in its purest form contains MDMA which produces similar effects to those in hallucinogen drugs and amphetamine drugs like Speed. As a result, Ecstasy can have an energizing effect with a feeling of euphoria and a heightened sense of touch, smell, sight and sound.
