I just know it happened. Maybe it’s not crystals forming in the brain, but that does happen, which was the point of my comment.

For something that totally happens, Google is completely unaware of it. Why can’t you just accept you’re wrong? Sounds like you confused what you heard.

LSD is one of the most potent, mood-changing chemicals. It is manufactured from lysergic acid, which is found in the ergot fungus that grows on rye and other grains. It is produced in crystal form in illegal laboratories, mainly in the United States. These crystals are converted to a liquid for distribution.

Created as a crystal, not crystals in the brain, seems like the most likely explanation.
