LSD is LSD-25 a chemical synthesized by Albert Hoffman in the 40's. It was the 25 of the LSD's. It didnt have the properties that they were looking for(some sort of medicine) and was put in storage. Supposedly Hoffman began having dreams about LSD-25 where he was seeing the chemical structure and thought it was worth another look. He began running studys and accidentally ingested some, probobly through the skin from handling. He began tripping and when he came down he began thinking about it and later did an experiment. He ingested a large amount thinking it was a small dose because since this was the 2nd LSD trip in history the potency was not known. Much research on LSD has been preformed and it is known to be one of the safest drugs in the world. Used responsibly and sparingly LSD is safer than smoking weed. It doesnt make your brain bleed, it doesnt collect in your spine, it wont make you go crazy unless there is already an underlying mental illness. I believe it is here for a reason why else was it discovered during the worst time in history? Its the cure to the atomic bomb, they came out at the same time.
