Can you become perma-fried if you take LSD too much? Is there a limit to how many times you should take it? One of my buddies is starting to take it pretty excessively (twice a week) and I'm curious/worried if anyone else is starting to notice a change in there friends, and what kind of change.
There doesn't seem to be a set limit to the amount of LSD an individual can take, physically or psychologically. "Acid casualties" from the 60s and 70s do seem to suggest that repeated chronic use of LSD can have long term effects on your brain and your mental well being. At the same time, however, practitioners like Timothy Leary took LSD over one thousand times in their lifetime with no apparent long term physiological damage?
Perhaps what is important is less how much you take, but more how you take it. People like Leary were very careful about set and setting when taking LSD.
I'm just curious what this will do to my friend in the long run, someone fill me in with experience.
