Surveys have consistently shown that at least 88% of adult smokers would like to stop smoking

Almost nine out of ten (88%)  of smokers state that they want to quit because of a health concern.  After health reasons, the next most common reason given for wanting to give up is a financial one.

The most important  element of the cessation process is the smoker's decision to quit, with the aid or method of secondary importance. 

Proven Methods Are

Acupuncture
Acupuncture involves needles being inserted into key pressure points on on the body. Patients are then left to relax for 30 minutes. The needles are then removed except for two tiny ones which remain in the ear. The idea is to touch an ear lobe when a craving comes on.

Cold Turkey
Stopping without any kind of aid. Although physical symptoms can be more extreme in the early few days, they fade away within the first two or three weeks. Most people give up smoking using this method.

Hypnotherapy
Although nicotine is a physically addictive drug, smoking also has many psychological associations. Hypnotherapy tries to alter the subconscious mind's dependence on smoking as a habit.
