Cannabinoid Receptor, Type 1 (CB1) antagonists were supposed to be the next big thing.
They're weight loss drugs, and with obesity rates rising and the diet craze showing no signs of abating, that's a large and growing market(...sorry). They worked, at least in the short term, and they were at least as effective as existing pills. They may even have had health benefits over and above promoting weight loss, such as improving blood fat and sugar levels through metabolic effects.
