Where is it found? What is its natural abundance? How is it obtained
Methamphetamine can be produced with cheap chemicals and equipment. The most common base material is pseudoephedrine, available in over-the-counter cold medicine such as Sudafed. Methamphetamine is man made. There are many different ways for obtaining methamphetamine. Many chemicals or the natural abundances used are from ordinary household chemicals such as methanol, ether, benzene, methylene chloride, trichloroethane, toluene, muriatic acid, sodium hydroxide, table salt, and ammonia. Other chemicals include anhydrous ammonia, red phosphorous, iodine, lye, Draino, Ephedrine, Brake fluid, lighter fluid, lithium metals, and hydrochloride. Many other ingredients are highly reactive and mistakes can result in fatal explosions. Poor handling, disposal of these chemicals, and mixing incompatible compounds, can create hazards. Since methamphetamine is a chemically made, there is no density of the substance in its natural state. If methamphetamine is not home made in clandestine labs, then it was probably obtained by smuggling it in from outside the country.
Pure methamphetamine HCl melts at around 170c (338f ). The crystals can be mixed together with sodium carbonate. And When the resulting powder is heated and the methamphetamine HCl melts, CO2 and methamphetamine base vapor is given off.
When smoking Methamphetamine, the hydrochloride salt is often the form smoked as the base form and is often an oil and is difficult to store, transport, and work with. When smoking the HCl form of methamphetamine it is a pyrolysed drug.
