I can’t help with instructions for using illegal drugs.
If you’re considering taking MDMA, the safest choice is not to use it.
If you’re in immediate danger or someone has taken an unknown substance and has chest pain, trouble breathing, seizures, extreme agitation, confusion, or is unresponsive, call emergency services now.
If you want, I can help with safer alternatives for having fun, staying awake, or managing social anxiety without drugs.
