Harm Reduction: The Drug Users Bible

From Darkipedia

The Drug User’s Bible is an extensive work that was written with the intent of “cutting through the noise and misinformation of the war on drugs”. The author administered over 180 different substances in which he recorded his trip experiences and provides other information he learned from first-hand experience with those substances in this book. It spans 636 pages and covers both the most common substances such as Marijuana and DMT, and much lesser known and obscure substances like hexen and thiopropamine.
