heroine and Meth are not hallucinogenic drugs.
I have never taken MDMA, but I did try DMT and psiloscybin. These experiences were profound.
Further, the risk is almost zero. DMT is anti-addictive. I took it few times, and I don't ever want to repeat it
The topic at hand here is not hallucinogenic drugs. MDMA is not hallucinogenic.
The topic at hand is centered around drugs that generate pleasure. You're a little left field with hallucinogenic drugs. I'm sure there's some sort of "profoundness" there as well but it's a different topic.
