Chantix is a new drug from Pfizer that helps smokers quit their addiction and has been getting plenty of positive reviews since it was released back in 2006. Hardly a Chantix review is written without the ex-smoker stating it to be a miracle drug. However, despite the glowing positive reviews, as with most pharmaceuticals, there are major negative side effects. Like depression leading to suicide. Yes, it has happened and their are a few Chantix lawsuits out there to prove it. In other words, Chantix is not for everyone, ecept now maybe for attorneys. No one ever really wins in a legal battle but the lawyers!
