چکیده
Background Approximately 25% of adults in the UK are smokers. Smoking is associated with numerous diseases including cancer and heart disease and smokers have reduced life expectancy. Nicotine in cigarettes renders them addictive so that smokers generally find it extremely difficult to give up their habit. Most smokers (~70%) say they would like to stop but some express an unwillingness or inability to do so in the near future. Nicotine replacement therapies attempt to substitute the nicotine obtained from smoking with that derived from gum, inhaler or patch, so that smokers are enabled to quit smoking and then gradually become independent of nicotine.
