1) Methods of Methamphetamine Synthesis
Methamphetamine Manufacturing:
? Two Primary Routes for Synthesis of Meth Used by Clandestine Laboratories in the USA: ? A) Pseudoephedrine Route
? Precursor is Sudafed from the drug store and involves the use of reducing agents like hydrogen or hydrogen iodide and red phosphorus.
? B) Phenyl Acetone Route
? Precursors are phenyl acetone or P2P, methyl amine and reducing agents.
Methamphetamine Manufacturing:
Pseudoephedrine Route: ? Substances that can be found at a laboratory
that used this route: -- Pseudoephedrine or ephedrine;
-- Hydrogen iodide and red phosphorus; or -- A special metal catalyst like palladium, platinum or
rhodium and a source of hydrogen gas; -- Hydrochloric acid; -- Organic solvents like ether, benzene, chloroform,
kerosene or white gas; and -- Lye or washing soda.

Pseudoephedrine Route:
Methamphetamine Manufacturing:
Phenyl Acetone Route: ? Substances that can be found at a laboratory that
used this route:
-- Phenyl acetone; -- Methyl amine or methyl amine hydrochloride; -- Formaldehyde, ammonia; -- Hydrochloric acid; -- Aluminum foil, mercuric chloride; -- Organic solvents like ether, benzene, chloroform,
kerosene or white gas; and -- Lye or washing soda.
Methamphetamine Manufacturing:
Phenyl Acetone Route (2): ? In addition, if the phenyl acetone precursor
needs to be synthesized first, then other substances that can be found at a laboratory may include:
-- Magnesium turnings; -- Benzyl chloride or benzyl bromide; -- Sodium cyanide or acetic anhydride; -- Ether or tetrahydrofuran; or -- Phenylacetic acid and thorium oxide.
