Back in the early 80's my friends and I did ALOT of microdot. Problem is we were told this was mescaline but I've read a bunch of stuff saying that it couldn't have been that. They were called strawberry (red) or yellow (sunshine). Most were asprin shaped but tiny about 2 or 3 mm. some were about the same size but were more barrel shaped. The high was very intense, speeding, colors, trails, laughing until our faces hurt etc. Smoking pot was usually a must to take the "edge" off. We also drank beer with it but it seemed like a waste of beer since you could drink large amounts without much effect.
We didn't have the internet to get info on it and so since the "dealer" was a very close friend of mine, she said mescaline, I believed her, but I see now this couldn't have been the case.
So, LSD or mescaline, it was awsome even though at 57yrs. old, I don't think I would do it now. After all these years I still wonder about the contents of these tiny pills that would last 8 to 12hrs+
Any input would be nice.
