If you find these instructions impractical, you probably never finished a high school chemistry course, let alone one in a Jr. college, and Fester says in the first chapter that the recommended level of knowledge for following these methods is at least completion of a college level organic chemistry course.
He only presents 1 theoretical method of LSD production, his deduction of the method pioneered during the 1980s by a lab in the United Kingdom based on chemicals which were added to the international watch lists shortly after said bust.
If you're so adept with the chemical extraction & refinement of Lysergic Acid into LSD, why is it you're not out spreading love across the country?
The methods he presents are for a serious production operation, not for you to make a batch for yourself and your friends, this is the entire point, this chemical can be produced in huge amounts by a very small lab, enough for virtually the entire country, this isn't a "Oh wow, look how I can spend an afternoon!" document, this is a document meant to spread proven methods of LSD production to the masses in the hopes that it will fall into the hands of those with the knowledge & inclination to return us to the swinging 60s.
