January 12, 2011 -1 New studies suggest that two smoking cessation drugs may help reduce craving-related brain activity in smokers. In one study, smokers were randomly assigned to a placebo or to bupropion for 8 weeks. Results showed that those who used the medication showed reduced craving activity in the brain as well as lessened self-reported craving. In the second study, researchers used neuroimaging to determine brain responses to varenicline, a medication designed to reduce withdrawal symptoms and nicotine reinforcement. Results showed that those who received the drug also experienced reduced brain activity in drug motivation areas and lessened cravings when exposed to smoking cues.
