Fact: you cannot overdose on LSD.
FALSE. Wtf.
Please do not take 5-7 hits. lol. I don't know what kind of diluted shit you are buying. When I was slanging that shit I would use rubber gloves or tweezers. I enjoyed my sanity when I wanted it there.
I watched my buddy eat a book, this was 15 years ago. He IS STILL tripping. He lives in a mental institution. His brain pretty much went full retard. I have seen this happen with a few different people. From different drugs, whether it be PCP, crack, meth or whatever it can really fuck up your brain.
Maybe you are talking about LSA (non chemist made)?
