Think back, who was it that told you psychedelics were harmful? Your teacher? Your government?
Keep shilling your paranoid delusions. Psychedelics, used in moderation, can be beneficial.
Just like sungazing, right?
"Psychedelics, Helps depression.", "Psychedelic drugs helps people face death."
New Scientist, 10 December 2016, p 8.The trouble is that government over-reaction has made drug problems worse and given drug cartels and dealers enormous wealth.
With one side-effect being a blanket ban on medical research on these substances. This very slowly changing.
There is undoubtedly a massive drug problem at present, but just trying to cut-off supply has done even a more damage than the prohibition of alcohol.
People are human and don't react kindly to bans of this sort by governments and many rebel. All that can be done is to try to educate people into the dangers of excesses in all areas.
Personally, I am against mind-altering drugs and excessive alcohol (the most damaging mind-altering drug around), but people are human individuals.
