Chantix Pfizer's anti-smoking medication faces new questions as Safe Medication Practices, a drug safety group, releases a report that shows 988 accidents linked to Chantix in the USA during the 4th quarter 2007. The FAA reacted to this report by banning the use of Chantix by pilots and air traffic controllers. Chantix has already been connected with psychiatric problems and this report shows links to heart trouble and diabetes.
