Hashish oil

The name is used by illicit drug users and dealers but is a misnomer in suggesting any resemblance to hashish other than its objective of further concentration. Hashish oil is produced by a process of repeated extraction of cannabis plant materials to yield a dark viscous liquid. In terms of its psychoactive effect, a drop or two of this liquid on a cigarette is equal to a single "joint" of marijuana.

LSD (LSD-25, lysergide)

LSD is an abbreviation of the German expression for lysergic acid diethylamide. LSD was first synthesized in 1938. Its psychotomimetic effects were discovered in 1943 when a chemist accidentally took some LSD. As he began to experience the effects now known as a "trip," he was aware of vertigo and an intensification of light. Closing his eyes, he saw a stream of fantastic images of extraordinary vividness accompanied by a kaleidoscopic play of colors. This condition lasted for about two hours.

LSD is usually sold in the form of tablets, thin squares of gelatin ("window panes"), or impregnated paper ("blotter acid"). The average effective oral dose is from 30 to 50 micrograms, but the amount per dosage unit varies greatly. The effects of higher doses persist for 10 to 12 hours. Tolerance develops rapidly.

HEROIN

First synthesized from morphine in 1874, heroin was not extensively used in medicine until the beginning of this century.

Pure heroin is a white powder with a bitter taste. Illicit heroin may vary in both form and color. Most illicit heroin is a powder which may vary in color from white to dark brown because of impurities left from the manufacturing process or the presence of additives, such as food coloring, cocoa, or brown sugar. Pure heroin is rarely sold on the street. A "bag"-slang for a single dosage unit of heroin - may weigh about 100 mg usually containing about five percent heroin.
