History of Methamphetamine
Methamphetamine is chemically similar to amphetamine, but more potent and easier to manufacture. Amphetamine was first synthesized in Germany in 1887 while Meth was developed in Japan in 1919. As it is water soluble, this drug is highly injectable.
中国A级毛片Meth was highly used by military combatants of the Allied and Axis forces during WWII to keep them awake. Japanese Kamikaze pilots were given high doses of this drug before a suicide mission. The use of injectable methamphetamine became rampant after the war when military supply of this drug became accessible to the Japanese civilians.
Methamphetamine became the wonder drug of the 1950’s. It was prescribed for weight reduction purposes and mental disorders such as depression. Its availability made this drug a popular choice among athletes, truck drivers and college students as a non-medical stimulant. Thus abuse of meth spread in the 1960’s.
By the 1970’s the United States Federal government made it illegal to use methamphetamine. At about this time, the production and distribution of the drug were controlled by motorcycle gangs across the US. Meth became the poor man’s cocaine.
Mexican drug cartels set up large laboratories in California in the 1990’s. At the same time small home labs proliferated across the US, spreading into Europe. Currently, this drug is mostly manufactured in Thailand, Myanmar and China.
