I totally agree that if it helps folks quit smoking cigarettes, it's a life-saver! The concept is brilliant, really, and I have no idea why it wasn't developed sooner. I almost wonder if Big Tobacco didn't work real hard to suppress pharmaceutical research in that area.

The drug was "fast-tracked," which means it didn't have the same amount or same length of testing that most drugs do. So the FDA and Pfizer are just now learning about some of the reactions they might have learned about earlier. My guess is that the benefits probably still outweigh the risks, and that's why it was fast-tracked. But it's been interesting to read about the reports of nightmares and hallucinations some patients have had. Anything that affects the neurochemicals in one way can affect them in others, clearly.

That's just awesome that it worked for you and your husband, Weedhound!
