Methamphetamine is made in labs. In the United States it is made from pseudoephedrine and other chemicals. In Mexico, where the drug is used the most, it is manufactured using a process known as the methamphetamine production from ephedrine and red phosphorous.  A first step is to react ephedrine with methylamine. Then phosphorous trichloride is used to separate the ephedrine from the methylamine. Finally, dimethylamine is used to neutralize the phosphorous trichloride and produce methamphetamine.
