As we can see, the ingredients in the table above can be found in many common household items. Organic compounds such as methylamine, ethyl ether, benzene, methanol and lithium aluminum hydride are extremely flammable, so there is always a great risk of explosion. Many meth labs in California and Missouri have used the anhydrous ammonia method or the Shake and Bake method, a simple one-step recipe where the meth yield is approximately 95% and a reaction period of 10 minutes and it will take up to about 2 hours for the total. preparation, production and clean-up time once the process is complete (Garriott, 2011). The main ingredients in this production are pseudoephedrine (cold medicine), lithium, water, Coleman fuel, ice packs and an explosive device. In addition, there are two other methods mainly used in the production of methamphetamine: the 2-phenyl-propanone (P2P) method and the red phosphorus (red P) method (Scott & Dedel, 2006). However, the anhydrous ammonia method is more popular because pseudoephedrine can be easily obtained in cold medicine and the production progress is quite simple and rapid, so this method can be applied in most clandestine methamphetamine laboratories on a small scale (Scott and Dedel, 2006). and the baking or "one pot" method involves mixing anhydrous ammonia extracted from fertilizer, pseudoephedrine from cold tablets, water and lithium in a small bottle of soda. These chemicals will react with each other to create a crystalline powder called methamphetamine (Scott and Dedel, 2006). This method is quick and easy, but it is also extremely dangerous because if oxygen gets into the bottle it can cause a big explosion. It is mainly used in small-scale laboratories where individuals can...... middle of paper....... They also create significant public health risks for people in surrounding areas because waste from methamphetamine production is dangerous. Therefore, it requires specialized training, detection and security measures that are lacking in most clandestine meth laboratories, as the cleanup and disposal steps can be very expensive. The property may not be able to be properly decontaminated to limit the risk of dangerous odors spreading to the surrounding area (Garriott, 2011). The amount of hazardous material waste produced is six times the amount of methamphetamine after each production cycle. Manufacturers often dump their waste in the yard or open spaces in surrounding areas, such as rivers or streams (Scott and Dedel, 2006). In doing so, the groundwater in these areas is contaminated and this leads to serious effects on public health...
