Commentary: Progress on nicotine replacement therapy for smokers

摘要

Four preparations for nicotine replacement therapy-chewing gum, skin patch, nasal spray, and buccal inhalator—have each been shown to approximately double a person's chance of stopping smoking. Success rates are modest, however, with typically about 10-30% of smokers continuously abstinent for 1 year, depending on the quantity and quality of behavioural or counselling support.
