Does Chantix make people crazy? Two new studies failed to turn up a link between the antismoking drug and psychiatric problems like depression and suicidal thoughts, government health officials said, but the findings are not definitive. The FDA has been looking into reports of mood disorders and erratic behavior among Chantix users since 2007. The agency said in a statement that two federally funded studies involving more than 26,000 people did not show an heightened rate of psychiatric hospitalizations among Chantix patients, compared with those using nicotine patches and smoking cessation treatments.
