Pharmaceutical researchers have realized that smoking weed gives people the munchies, so logically they decided that deactivating the receptors in the brain responsible for getting high would give you anti-munchies. They took a long time to think this up. They tested a drug that took the action of reverse munchies and found that it was incredibly effective. The drug was approved in Europe and appeared to be one of the best weight-loss drugs in history.
Rimonabant is inexpensive, effective, and totally nonaddicting. Unfortunately, in addition to giving users anti-munchies it was found to have a prominent side effect called anti-happiness, aka suicidal depression. In the months following the drug’s clinical trials, there were over 70 patients displaying signs of suicidal thoughts, two completed suicides, a host of seizures, precipitated multiple sclerosis, domestic abuse, and a man who strangled his daughter. All in all, the “side effects” weren’t really worth people losing a few pounds.
