LSD, the most powerful known hallucinogen, is derived from a fungus that grows on rye and other grains. In its pure form, a tablet the size of an aspirin would be equivalent to 3,000 doses. This drug radically changes an individual’s mental state by distorting the perception of reality and producing behavioral changes that are often multiple and dramatic.

Pure LSD may appear as a fine white powder poured into capsules or may be pressed into tablets. This odorless and tasteless drug can be diluted into a liquid and then dropped into the eyes, absorbed into blotter paper, postage stamps, sugar cubes, gum, candy or cookies that can be licked or eaten.
