A person who is a non-chemist needs someone who has successfully performed said reaction before to show them the correct steps to take. Otherwise, it's not safe. Don't forget to add a tablespoon or two of 3% OTC hydrogen peroxide to the reaction mixture to active it, and also you should filter your final product with anhydrous acetone to remove many of the impurities inherent in the shake and bake reaction. Without that filtration, which can remove 50% by weight of your impure product, the shake and bake method produces only averagely good methamphetamine hydrochloride. The readily available fertilizer known as ammonium nitrate should be used in place of anhydrous ammonia, which is now hard to obtain. The HCl gassing step to convert the freebase to its water soluble HCl salt should be carried out in a well ventilated area, such as outdoors. The most common dangers involving this clandestine operation are that you'll blow yourself up, burn yourself with HCl vapors, or go to prison, but hey, methamphetamine gives you a great high!
