Methamphetamine chemical properties

Inhalant abuse is also termed volatile solvent abuse. It should be noted that many drugs besides those classified as inhalants can be administered by inhalation, including marijuana, cocaine, heroin, methamphetamine, fentanyl patches, and nicotine. These drugs are not volatile solvents and have different physical and chemical properties therefore, they are not classified as inhalants. Inhalants are chemicals that are volatile, meaning they can readily vaporize from... 

Alan Baxter lost his bronze medal in the winter Olympics in 2000 because he used an American Vick inhaler and not a British one.1,2 Note the position of the CH3 attached to the central carbon atom (Figure 2.18). The British Vick inhaler contains a mixture of menthol, camphor and methyl salicylate the American Vick inhaler also contains L-methamphetamine. This is used as a decongestant and has no performance-improving properties, whereas its optically active isomer D-methamphetamine (commonly known as speed ) is a prohibited drug and is a performance improver. However, the Olympic Committee does not distinguish between these two isomers in its detective work and chemical analysis. It therefore reported that his urine contained methamphetamine and did not report that it was the ineffective l form. The committee took the medal away from him. If they only had known their chemistry and all about optically active isomers. 

The persistence of illicit drags or ary chemical in an aquatic ecosystem depends on its physicochemical and ecosystem-specific properties. Among these are concentration of dissolved/suspended oi nic matter, solubility, microbial population, etc. (Baughman et al., 1978 Loganathan and Kamian, 1994). Persistence of methamphetamine, MDMA, and related compounds in aqiratic systems are a function of physical (e.g., volatiUzation from, and adsorption to, suspended sohds and sediment), chemical (hydrolysis and photolysis), and biological removal (microbial degradation and uptake)...
