Both terms adopted and used in naming the class of therapeutic drugs for [[MDMA]] and related compounds were chosen with the intention of providing some reflection of the reported psychological effects associated with drugs in the classification and distinguishing these compounds from classical [[psychedelic drug]]s such as [[LSD]], [[mescaline]], and [[psilocybin]] and major [[stimulants]], such as [[methamphetamine]] and [[amphetamine]].<ref name="NicholsYensenMetzner1993" /> Chemically, MDMA is classified as a [[substituted amphetamine]] (which includes stimulants like dextroamphetamine and psychedelics like [[2,5-dimethoxy-4-methylamphetamine]]), which makes MDMA a [[substituted phenethylamine]] (which includes other stimulants like [[methylphenidate]] and other psychedelics like [[mescaline]]) by the definition of amphetamine. While chemically related both to psychedelics and stimulants, the psychological effects experienced with MDMA were reported to provide obvious and striking aspects of personal relatedness, feelings of connectedness, communion with others, and ability to feel what others feel—in short an empathic resonance is consistently evoked.<ref>{{cite journal|last1=Metzner|first1=Ralph|title=Letter from Ralph Metzner|journal=Newsletter of the Multidisciplinary Association for Psychedelic Studies MAPS|date=1993|volume=4|issue=1|url=http://www.maps.org/news-letters/v04n1/04143met.html|access-date=8 January 2015}}</ref> While psychedelics like LSD may sometimes yield effects of empathic resonance, these effects tend to be momentary and likely passed over on the way to some other dimension or interest. In contrast, the main characteristic that distinguishes MDMA from LSD-type experiences is the consistency of the effects of emotional communion, relatedness, emotional openness—in short, empathy and sympathy.<ref name="NicholsYensenMetzner1993" />
