Tracking down the reference for the process of making meth with pseudoephedrine and red phosphorous led me to stumble upon the above video interview with Uncle Fester, author of books like Secrets of Methamphetamine Manufacture and Practical LSD Manufacture.
Uncle Fester also has a website, which includes a PDF of an interview done by the staff Loompanics and an article on meth production in which he is quoted. I recently finished watching the first three seasons of Breaking Bad, so I find this stuff interesting.
I might as well also plug my friends (and past EsoZone sponsors) Last Word Books and Earthlight Books, who have a wide variety of old Loompanics books in stock.
