Most of the adverse reactions associated with Chantix are not life threatening, and not all users will experience any side effects when taking this drug. Commonly, Chantix can cause upset stomach (nearly a third of users will experience this), gas, constipation, altered taste, and sleeping issues. Other relatively minor side effects are also possible.[3]

In addition, there is a risk of losing consciousness or blacking out on Chantix, which is why bus drivers, truck drivers, pilots and air traffic controllers are typically barred from taking the drug.[2]
