Did Chantix Cause Man to Kill Himself?

A British television executive committed suicide two months after he started taking the smoking cessation drug Champix, which is marketed as Chantix in the United States.

Omer Jama, 39, of Bolton, England, was a Sky Sports video editor who was taking the drug to try and kick his pack-a-day habit; it is being reported by London's Daily Mail.
