It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...
Diagnostic impurities are the naphthalenes 1-benzyl-methylnaphthalene and 1,3-dimethyl-2-phenylnaphthalene, [108] arising in the Nagai and Leuckart routes, and cis-or trans-1,2-dimethyl-3-phenylaziridine, ephedrine, or erythro-3,4-dimethyl- 5-phenyloxazolidine, arising in the Nagai and Emde routes; these are absent in the reductive amination ...
Toxic chemicals resulting from methamphetamine production may be hoarded or clandestinely dumped, damaging land, water, plant life and wild life, and posing a risk to humans. [15] [10] Waste from methamphetamine labs is frequently dumped on federal, public, and tribal lands. The chemicals involved can explode and clandestine chemistry has been ...
In 2012, 16,000 prescriptions for methamphetamine were filled, approximately 1.2 million Americans reported using it in the past year, and 440,000 reported using the drug in the past month. [2] Until the 1980s, the methamphetamine market in the United States was dominated by outlaw motorcycle gangs, namely the Hells Angels.

STP was first synthesized and tested in 1963 by Alexander Shulgin, who was investigating the effect of 4-position substitutions on psychedelic amphetamines. [3]In mid-1967, tablets containing 20 mg (later 10 mg) of STP were widely distributed in the Haight-Ashbury District of San Francisco under the name of STP, having been manufactured by underground chemists Owsley Stanley and Tim Scully.
In most countries, the drug is a controlled substance and its possession and sale are illegal. MDA is rarely sought as a recreational drug compared to other amphetamines; however, it remains widely used due to it being a primary metabolite, [3] the product of hepatic N-dealkylation, [4] of MDMA. It is also a common adulterant of illicitly ...
