The materials discussed in this book are legal despite the fact that they have psychotropic properties. Some are far more potent than many controlled substances. They have not been designated as illegal by any state or federal codes, because they are relatively obscure and have never been subjected to abuse. Although chemicals such as mescaline and lysergic acid amide are controlled by Title 21 of the United States Code (1970 edition), their plant sources (except for ergot and peyote) are not so controlled. It is therefore legal to possess San Pedro cactus, morning glory seeds, Hawaiian wood rose, etc., as long as there is no indication that they are intended for other than normal horticultural or ornamental purposes. The materials listed here are legal at the time of this writing. They may be outlawed at any future date. It may be of some interest to some readers that the Church of the Tree of Life has declared as its religious sacraments most saubstances in this book. Because these substances were legal at the time of the Church's inception and incorporation, their use cannot be denied to members through any future legislation without directly violating the Constitution's guarantee of religious freedom. Those interested should send a stamped self-addressed envelope to the Church of the Tree of Life, 405 Columbus Avenue, San Francisco, California 94133. Although there exist both state and federal laws against Psilocybe mushrooms and peyote, we have included these in our book of legal highs. We do so because of the glaring weaknesses in the legislation regarding these. Peyote is allowed to members of the Native American Church, because it was in use by the Plains Americans as a religious sacrament long before the caucasian immigrants and their progeny devised laws against it. Even today, a number of legitimate cactus nurseries still ship cuttings and seeds of this cactus to all parts of the country with apparent impunity. Many species of psilocybin-bearing mushroom grow wild throughout most parts of the United States, and can in no way be controlled. Since the original publication of this book, there has been a virtual mushroom revolution. Head shops and mail order houses now sell complete kits for home cultivation of Psilocybe cubensis (spores included). The flagrant ignorance of the law-makers is reflected in the fact that in Title 21 the alkaloid psilocin is misspelled as psilocyn. This small error is a product of the same mentality that classified cocaine as a narcotic in the 1922 Amendment to the Narcotic Drugs Import and Export Act and deliberately retains the error to this day. The purpose of this book is to provide the user with concise reference information on various legal psychotropic materials. These include plant materials in their crude hebal form, and chemicals either synthesized or extracted from natural minerals. For each item there is a brief description of the material, the method of preparation, dosage and use, analysis of active constituents, effects, contraindications (side effects, dangers, etc.), and names of commercial suppliers. The latter are given as letter codes. The corresponding names and addresses are to be found in the section titled "Suppliers." Because of increasing interest in horticulture of psychotropic plants, sources of seeds and live plants are also given. Some of the materials discussed are very dangerous and are strongly disrecommended. They are included because many people have already shown an interest in experimenting with them. We feel that it is important to discuss them while clearing indicating their dangers. Although we feel confident in the accuracy of the information in this guide, we can in no way assume responsibility for the experiences of persons following these data for personal drug use. This book is intended as a contribution to the world of information and general knowledge. It must not be construed as encouragement or endorsement, by the author or publisher, of the use of any of the materials herein described.
