How did amphetamines become a popular weight loss drug?
When it got approval from the MA to market it as a diet drug. Dieting was actually the main market of these generic imitators because the fad doctors had picked up on this stuff even though it was not being advertised, it was sort of represented as a dodging medical use of amphetamine in the early 40's. It was known that amphetamine would restrict people's eating and help them lose weight. So there was a big booming business in those generic knockoffs that caused weight loss but could not be advertised by a legitimate drug company. They used nothing approved by the MA's counsel and pharmacy. The MA's counsel and pharmacy is this body experts that would look at clinical trial results to show that a drug was safe and effective and if they were convinced that it was safe and effective for a particular use, it could be advertised for that use under this voluntary system of regulation. Now by this time actually the federal system of regulation had started to kick in, Federal Government now required evidence that a product was safe before it could be marketed. The efficacy regulation was not in place, but was still the MA's responsibility.
