As we can see, the ingredients in the table above can be found in many common household items. Organic compounds such as methylamine, diethyl ether, benzene, methanol and lithium aluminum hydride are extremely flammable, so there is always a large possibility of an explosion occurring. Many meth labs in California and Missouri have used the anhydrous ammonia method or the Shake and Bake method, a simple one-step recipe in which the meth yield is approximately 95% and a reaction period of 10 minutes and it will take up to approximately 2 hours for the total. time for preparation, production and cleaning at the end of the process (Garriott, 2011). The main ingredients of this production are pseudoephedrine (cold medicine), lithium, water, Coleman fuel, ice packs and an explosive device. Besides that, there are two other methods mainly used in methamphetamine production: the phenyl-2-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 process is quite simple and quick, so this method can be applied in most small-scale clandestine methamphetamine laboratories (Scott & Dedel, 2006). and the Bake or "one pot" method is prepared by mixing anhydrous ammonia extracted from fertilizer, pseudoephedrine from cold tablets, water and lithium in a 2 small soda bottle. These chemicals react with each other to create a crystalline powder which is methamphetamine (Scott & 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 large explosion. It is used primarily in small-scale laboratories where individuals can...... middle of paper......on. They also create significant public health risks for people in the surrounding areas because the waste from methamphetamine production is dangerous. Therefore, it requires specialized training, detection and safety precautions that are lacking in most clandestine meth labs because the cleanup and disposal step can cost a lot of money. It may not be possible to adequately decontaminate the property to limit the risks of spreading hazardous odors to surrounding areas (Garriott, 2011). The amount of hazardous material waste produced is six times greater than the amount of methamphetamine after each production cycle. Producers often dump their waste in backyards or open spaces in surrounding areas such as rivers or streams (Scott & Dedel, 2006). In doing so, the groundwater in those areas becomes contaminated and causes serious effects on public health.
