Pfizer Inc. said it’s pausing worldwide distribution of its smoking-cessation drug Chantix after finding elevated levels of nitrosamines, a likely carcinogen, in the pills.

The drug giant is also recalling certain lots of Chantix but didn’t say how many. The distribution halt is out of an abundance of caution, pending further testing, the company said in an email.
