Ecstasy is a psychostimulative drug (ab)used mostly by teenagers and young adults in discotheques and on the "rave" parties. Older adults ecstasy abusing cases are very rare. Among four cases of ecstasy abuse with fatal outcome noticed and examined in Slovenia, two were examined at our Institute of Forensic Medicine in Ljubljana. The first case was the accidental intoxication with 3,4 methylenedioxymethamphetamine (MDMA) on "rave" party, the second case was suicidal intoxication with combination of insulin and MDMA. Because of the increasing popularity of MDMA, it is important for all emergency physicians to be well educated in prompt recognition of MDMA intoxication symptoms. It is important that emergency physician carefully examines the death scene.
