Ecstasy

More commonly known today by the street name Ecstasy, MDMA (Systematic name:3,3-methylenedioxy-N-methylamphetamine) is a synthetic drug of the phenethylamine family whose primary effect is to stimulated the brain to rapidly secrete large amounts of serotonin, causing a general sense of openness, energy, euphoria, and well-being. Tactile sensations are enhanced, making general physical contact with others more pleasurable, but contrary to popular mythology it generally does not have aphrodisiac effects. Its ability to facilitate self-examination with reduced fear has proven useful in some therapeutic settings, leading to its 2001 approval by the United States FDA for use in patients with post-traumatic stress disorder.

Though there are no known overdoses from MDMA specifically, acute dehydration is a risk among users who are highly physically active and forget to drink water, as the drug may mask one's normal sense of exhaustion and thirstiness. Another danger comes from other more dangerous chemicals (such as PMA or methamphetamine) which are often added to ecstasy tablets to increase manufacturer profits. Long-term effects in humans are largely unknown and the subject of much controversy.
