Summary
The investigators hypothesize that varenicline will dose dependently attenuate the subjective effects of cigarettes after a period of abstinence. Also, treatment with varenicline will dose dependently weaken the severity of nicotine withdrawal symptoms. Thirdly, we hypothesize that treatment with varenicline will dose dependently decrease cigarette self-administration in the model proposed.
