What I will say is that some people seem to come back from it convinced that acid will change the face of humanity and society in some sort of miraculous way. But when pressed they can't say how. I don't think it's wrong to combine this with the fact that LSD can cause feelings of the profound over the most mundane or nonsensical things and come to the conclusion that they're probably off on one...
As I said - do you need acid to see the problems in our human society?
