LSD (Molecule of the Month for January 2006)

d-lysergic acid diethylamide, acid

LSD (d-lysergic acid diethylamide), commonly called "acid," is the most powerful known hallucinogen - a drug that radically changes a person's mental state by distorting the perception of reality to the point where, at high doses, hallucinations occur. Even in very minute doses 0.05g LSD can significantly alter one's perceptions to the point of hallucination. Although it is derived from a fungus that grows on rye and other grains, LSD is semi-synthetic and has to be chemically manufactured in illicit laboratories.

Pure LSD is a white, odorless crystalline powder that dissolves in water. Because an effective dose of the pure drug is almost invisible, it is mixed with other substances, such as sugar, and packaged in capsules, tablets, or solutions, or spotted on to gelatin sheets or most commonly on pieces of blotting paper.

LSD is ingested orally. A microdot tablet or square of the perforated LSD paper is placed in the user's mouth, chewed or swallowed. Paper squares are most common because their small size makes them easy to conceal and ingest. Also, because LSD is not injected or smoked, paraphernalia are not required.
