Very sound advise. I know a number of people who regularly took psychedelics/smoked a ton of weed in the 90's and who could now be regarded as casualties. Maybe some form of psychosis would have happened to these people anyway, but IMO psychedelics is not a "one size fits all" type thing. Many people do clearly get something out of taking psychedelics, but other people with genetics tending on the psychotic end of the spectrum clearly should not, in my opinion. Also I think we have survivor bias in many of these conversations on HN - in that people who are in a bad place are not positing on hacker news. Those people are surviving and trying to get their shit together.
