psychedelics are not physically addictive (shrooms, LSD). MDMA is, but the comedowns can be pretty nasty which keeps many people off. Biggest danger with pills these days is that, unless you test, you got no fucking idea what's in them. Binging every week doesn't help either, rule of thumb for MDMA is once every 3 months; every week is just fucking asking for serotonin syndrome. do not.
be smart about your drugs and they will not hurt you.
