New research shows nearly half of smokers who try to quit manage to last only a week or less before taking up smoking again. It found that 85 per cent of smokers had tried to quit smoking in the past with 25 per cent having tried to quit two times and 15 per cent trying three times.

The most common reason smokers gave for being unable to quit was a lack of willpower with 52 per cent saying they didn't have the motivation.
