MDMA is an empathogenic drug of the phenethylamine and amphetamine classes of drugs. MDMA has become widely known as 'ecstasy' (shortened to 'E', 'X', or 'XTC'), usually referring to its street pill form, although this term may also include the presence of possible adulterants. The term 'molly' or 'mandy' colloquially refers to MDMA in powder or crystalline form, usually implying a higher level of purity. MDMA can induce euphoria, a sense of intimacy with others, and diminished anxiety. Many studies, particularly in the fields of psychology and cognitive therapy, have suggested that MDMA has therapeutic benefits and facilitates therapy sessions in certain individuals, a practice for which it had formally been used in the past. Clinical trials are now testing the therapeutic potential of MDMA for post-traumatic stress disorder (PTSD) and anxiety associated with terminal cancer.
