Obviously no one can vouch for this topic, but consider the vulnerability associated with intense psychedelic use. If someone wanted to make you die in real life, black mail you, etc, this would be very good leverage. I've been told that the government likes leverage like this for maintaining control/order of the people who work for it. But who really knows, could all be conspiratorial mumbo jumbo. What is known is that the government invested a lot of time into studying psychedelics for purposes of mind control, IE, something that is not in the interest of the practitioner whatsoever.
Me personally... If I had to choose between being a psychedelic user on my own with my own tribe, or durring a government evaluation of my character, I think it's probably safer to choose the former not the latter.
Also, not super interested in barbed wire lunches, being used for psychological experiments, armed guards behind me while I write if statements, etc. Not my thing, but I know some people are fine with the trade.
