LSD is one of the most potent, mood-changing chemicals . Found in the ergot fungus that grows on rye and other grains, lysergic acid is manufactured. Laboratories mostly in the USA produce it in its crystalline form . Distribution liquid is then obtained from the crystals. It is odorless, colorless, and has a slightly bitter taste. Known as “acid” and by many other names, LSD is sold on the street in small tablets (“microdots”), capsules or gelatin squares (“window panes”).
