Ecstasy is a drug made up of methylenedioxymethamphetamine (MDMA) which is used in recreational and therapeutic settings. It makes users feel extreme positive emotions by decreasing the fear response from perceived emotional threats. It was initially used in therapeutic settings but its usage has shifted to mostly recreational use due to the restrictions of human testing by the FDA.
Therapeutically it has been used to treat post traumatic stress disorder (PTSD), depression, and anxiety disorders. There are health risks associated with MDMA when used recreationally because street drugs contain very little, if any, actual MDMA. A recent analysis of confiscated MDMA showed that only 13% had any MDMA at all. If it was present it was a very small amount. Dangerous unknown fillers are used instead that can pose serious health risks. It is also dangerous to use it in conjunction with other drugs or alcohol.
