Abstract in brief

  • This study analyzed 5,786 ecstasy tablets to determine how different chemical substances in them relate to users' reported effects, highlighting that many tablets contain a mix of drugs rather than pure MDMA.
  • MDMA was strongly linked to positive, desirable effects in users, especially at higher doses, but other substances like mephedrone and pfluoroamphetamine were also considered somewhat pleasurable, while drugs like mCPP and PMMA were associated with negative effects.
  • The findings help clarify how the variable chemical makeup of street ecstasy influences user experiences, ultimately reinforcing MDMA's central role in the ecstasy market despite the presence of other substances.]

@wanko450 @Nuyoricansoul77 @WeAreTheLoopUK @KendalCalling We are talking harm-reduction here e.g A young girl taking 2 of these tablets could easily die, so this not just a matter of opinion. Protocol in therapeutic settings sees anything over 125mg as detrimental. See https://t.co/I4p3hDDpRx and https://t.co/jRJzPwdRMt for more info
