During an undergrad research project in a hospital, I had access to a medical library and found a few articles on persistent visual tracers following LSD use. I can't find them now, but I turned this up in the British Journal of Psychiatry
"A chronic impairment of colour vision in users of LSD." http://bjp.rcpsych.org/content/140/5/518.short
Do you have numbers and studies on this? Was it just LSD or have they been chronic multi-drug users for multiple years?
Because your statements directly conflict with the state of the art of current research.
>> There are a few writers that have tried drugs and are completely honest about them, but they are very few. It is very hard for a drug user to be honest about drugs. I would recommend Philip K Dick. If anyone wants to try hard drugs, please read "A scanner darkly", and then read a Philip K Dick biography to see that he knew what he was talking about.
PKD and his friends were indeed into all sorts of things, and got into all sorts of trouble.
His main complaint seems to have been that nobody told them what was safe and what was not, and that through innocent experimentation all sorts of bad things happened.
Hysterical disinformation, which is all we've had from government for around 30 years now, does nothing to help this. Nothing.
