Everyone should know by now that smoking kills (About.com). After several class-action products liability lawsuits against tobacco companies were settled for millions, smoking-cessation programs and anti-smoking aids became widespread, including nicotine patches and pills meant to curb nicotine cravings.
But one such drug manufactured by Pfizer, called Chantix, has been blamed in three separate lawsuits for allegedly causing its users to attempt suicide, with at least one success (Reuters). Chantix hit the US market in 2006.
