Good and Bad acid

Can there be good or bad acid? As long as its actually LSD isnt the only varible the amount? I have heard people say to me and on various web sites that they got bad acid and tripped out bad.

There is no such thing, as long as it is LSD the only difference would be the potency. I hear this alot, many people blame bad trips on the fact that they got "bad acid" Whats really to blame would be the set, setting, or dosage.

There are some who believe that all black-market acid is impure, being contaminated by ergot alkaloids. It was discussed here



I am not sure about the validity of this argument...
