Study reveals other smoking cessation aids are tied to more successful quits

Findings seen for both discontinuation overall and discontinuing daily smoking

Combining varenicline with nicotine patch, extending treatment from 12 to 24 weeks did not increase smoking cessation rates

0.5-mg and 1-mg tablets may contain levels of N-nitroso-varenicline at or above levels approved by the FDA

Significantly fewer adverse reactions reported by those in the cytisine group versus the varenicline group
