I really hate bad information written in articles. The article states: "the FDA is standing behind Chantix,
which has a 12-month quit rate of 22 percent, slightly better than counseling or nicotine-replacement therapy such as the patch or gum." They get that 22% number from an article on motherjones.com which states "The
trials showed that about 22 percent of Chantix users who took the drug for
three months were able to kick the habit for a year or more."
That motherjones.com article also quotes "Lirio Covey, a professor of clinical psychology at Columbia University who worked on Pfizer's clinical trials" and "has received nearly $80,000 from Pfizer this year to study the effects of smoking cessation on mood" as saying "the key facts are these: Millions have taken Chantix, so the number of people claiming severe side effects is relatively small. (In her estimation, the drug's benefits outweigh its risks.) She also says it's still not clear whether the side effects are the direct result of the drug, or of nicotine withdrawal."
I guess some researchers don't care how many people die or get hurt, as long as they get their funding. "The drug's benefits outweigh its risks" - holy crap.
