Rob Clarke, author of Marijuana Botany, illuminates the world of hashish from growing the marijuana plant to collecting its valuable resin and making hashish, a concentrated form of marijuana's active ingredients. His serious study demystifies hashish and debunks long-held misconceptions.

Clarke traces the history of hashish and surveys both ancient and contemporary hashish-using cultures. In clear, understandable terms, he discusses the ingredients that make up hashish and the biochemistry of the psychoactive constituents and their actions in the human body. Readers learn the how-to of informed purchase and consumption. Smoking techniques and cooking recipes emphasize healthful means of ingestion for recreational and medicinal users.

After depicting the how-to of traditional manuffacturing methods, Hashish! describes and illustrates innovative high-tech production techniques that improve on traditional practices. Readers learn how to combine simple tools with a basic understanding of potency --which Clarke imparts in everyday terms-- to perform the new art of making extremely potent hashish. The author concludes by showing how kitchenware found in any home can be used in novel ways to make hashish for personal consumption. All the hashish-making techniques are practical, non-chemical, and easily performed.
