Usage Note: Native American is now fully established in American English as an equivalent of Indian, being acceptable in all contemporary contexts and preferred in many. It is especially appropriate as a term of respect used by outsiders, who may have concerns that Indian could cause offense by its association with longstanding cultural stereotypes.
In Basel, Switzerland, Albert Hoffman, a Swiss chemist working at the Sandoz pharmaceutical research laboratory, accidentally consumes LSD-25, a synthetic drug he had created in 1938 as part of his research into the medicinal value of lysergic acid compounds.
LSD is non-addictive. However, acute adverse psychiatric reactions such as anxiety, paranoia, and delusions are possible. LSD was first synthesized by Albert Hofmann in 1938 from ergotamine, a chemical derived by Arthur Stoll from ergot, a grain fungus that typically grows on rye.The short form LSD comes from its early code name LSD-25, which is an abbreviation for the German Lysergsaeure-lysergsÃ¤ure diethylamid followed by a sequential. number single dose of LSD may be between 40 and 500 microgramsâan amount roughly equal to one-tenth the mass of a grain of sand. Threshold effects can be felt with as little as 25 micrograms of LSD. Dosages of LSD are measured in micrograms (Âµg), or millionths of a gram.
