The Institute for Safe Medication Practices monitors the reports of adverse drug events that FDA receives each quarter. In its most recent Quarter Watch report, patient safety analysts noted that the stop-smoking drug Chantix has a higher likelihood of triggering suicidal or homicidal thoughts than any other medication.
Comparing Chantix to drugs like Singulair, Paxil or Seroquel revealed that Chantix outnumbered the others nearly 3 to 1 when it came to suicidal or self-injurious thoughts. There was a five fold difference between Chantix and other drugs with respect to homicidal plans.
The authors of the report call for stronger, clearer warnings about the potential risks of this stop smoking drug, especially its tendency to trigger aggression and violence. The drug has also been linked to blackouts and impaired vision and probably poses risks for people such as pilots, air traffic controllers, fire fighters and other first responders.

There are many others. Chantix has helped many people quit, but others have found out too late that the drug can have disastrous side effects.
