Long Description***This paperback edition has a new introduction by the author and updated content. This is the third and final volume of North Atlantic Books’ updated paperback edition of Dale Pendell’s Pharmako trilogy, an encyclopedic study of the history and uses of psychoactive plants and related synthetics first published between 1995 and 2005. The books form an interrelated suite of works that provide the reader with a unique, reliable, and often personal immersion in this medically, culturally, and spiritually fascinating subject. All three books are beautifully designed and illustrated, and are written with unparalleled authority, erudition, playfulness, and range. Pharmako/Gnosis: Plant Teachers and the Poison Path includes a new introduction by the author and as in previous editions focuses on plant-based and derivative psychedelic “teachers” (including ayahuasca, peyote, LSD, and DMT) and on the “poison path” of substances such as belladonna, ketamine, and ibogaine. Each substance is explored in detail, not only with information on its history, pharmacology, preparation, and cultural and esoteric correspondences, but also the subtleties of each plant’s effect on consciousness in a way that only poets can do.The whole concoction is sprinkled with abundant quotations from famous writers, creating a literary brew as intoxicating as its subject. The Pharmako series includes the predecessor volumes Pharmako/Poeia (which covers tobacco, alcohol, cannabis, opiates, salvia divinorum, and other substances) and Pharmako/Dynamis (focusing on stimulants and empathogens).

This symbology was developed by the Plessey Company in England. A variation of Plessey was used by the ADS Company and is known as Anker Code. Anker Code was used in European point of sale systems prior to the advent of EAN. Another variation is known as the MSI Code.

Plessey offers a full range of HEX digits 0-F. The bit pattern of the bits sets the high order bit at the right which is reverse of how we normally think of bits these days. (MSI puts the high order bit on the left).

The start bar is always "D" (1101) and the terminator can be two binary 1's (11) if the barcode is to be read from left to right only. If the barcode can be read in either direction the terminator will be a single binary 1 (1) and is followed by a reverse of the start character or the "B" (1011).

You can use the stripe bits can be used to generate the graphic pattern. If you want to see this trick, check out the MSI Code page. Plessey uses a cyclic (or polynomial) check code technique which is applied to the reading of barcode labels and transmission of data. This technique is a fair compromise between the extra redundancy and the error detecting power. Roughly one undetected error per hundred million 6 digit transactions.
