Symptoms such as cravings are common when someone stops using tobacco. Nicotine is the addictive ingredient in tobacco. Nicotine-replacement therapy helps ease these symptoms while the person works on changing behaviors that are associated with tobacco use.
Symptoms may include strong cravings, anxiety, increased hunger, and difficulty concentrating. They're usually the most intense in the first week or so after quitting. Most symptoms pass after a month, but cravings may ocassionally return.
Treatments include medications, nicotine replacement products, and counseling. Support groups help people deal with withdrawal and overcome their dependence on nicotine.
