Smoking is a major health problem with a direct link to elevated heart- and lung-related
problems. Nicotine is highly addictive, which makes quitting difficult and relapse after
quitting highly probable. Any type of sleep disturbance may make quitting even harder. The
purpose of this study is to evaluate the effect of bupropion and nicotine replacement
therapies (NRT) on sleep disturbances. In turn, this might show how such medications affect
attempts at smoking cessation.
