How is meth made?
<|assistant|>
Methamphetamine, or "meth," is a synthetic drug that is often made by individuals in clandestine laboratories. Common methods of manufacturing meth include the following: 1) extracting pseudoephedrine or phenylpropanolamine from over-the-counter medications and then converting the drugs to methamphetamine; 2) producing meth from ephedrine or pseudoephedrine HCl with the assistance of certain chemicals and processing; or 3) using an industrial process known as the "shake and bake" method, which involves cooking anhydrous ammonia and methamphetamine over heat. Meth can also be made with the use of precursor drugs such as antifreeze and drain cleaners.
