flameReal talk:
Not sure of your ages and shit, but once you hit around 22-26 you start losing friends, kids you went to high school with, or your friend's siblings to drug addictions.
Sometimes you have no idea until its too late. Literally lost one of my closest friend's older brother last year to an overdose. Kid was in his 4th year of law school, dean's list, about to graduate, and I don't think anyone saw it coming.
If you're trying to become a statistic, go ahead and keep taking them. One bad batch of shrooms is enough to kill you, and once you get addicted to harder drugs than weed the road to recovery is treacherous.
For real, don't do drugs. It's not attractive, it's life ruining, and one criminal record is enough for you to never get a career out of high school/college.
I empathize with your losses. I understand what it's like to lose someone to a downward spiral of addiction.
however the thread is specifically asking about psychedelic drugs, which are an entirely different animal. I suggest you do research on this to understand the difference, but I can help out with the basic stuff -
they're virtually impossible to overdose on, no physically addictive properties, is not checked in any standard drug test, "life-ruining" is a really blanket assumption to make, because for many it is "life-saving" or "life changing". as with anything else, personal responsibility and knowledge are important.
edit: that's a compelling argument #85. although the kinds of violent elements you presented aren't usually as prevalent when dealing psyches, you make a pretty convincing point that I haven't ever considered
