does chantix contain nicotine
Chantix does not contain nicotine. It contains varenicline which acts on nicotinic receptors in the brain and controls the craving. Chantix will not cause a positive test for nicotine. I also do not expect either nicotine or its metabolites to be detected after nine days of abstinence in the usual drug tests, though there are highly sensitive tests available which can detect the presence of nicotine for up to three months after use.
