I took a ton of acid (blotter) in the late 70's and early 80's as a teen, and then again in the late 90's (window pane and liquid eyedrops), and I just have to say, I, personally, have mixed feelings about this sort of thing being heralded as some sort of metaphysical panacea.
As I mentioned in a previous post, I became addicted to opiates in the mid 2000's and lived as a zombified-but-somehow-functional heroin addict for about 4 years.
There is no doubt, in my personal case, that acid and mushrooms (that I often hand-picked in cow pastures after rainstorms here in central Florida) gateway-ed me into harder, destructive "escapes", and for that reason, I cannot fully endorse this sort of thing.
