Better breathing: your lung capacity can increase by as much as 10% within one year of quitting smoking. This allows you to perform more daily tasks without becoming out of breath. You may also eventually lose your ‘smoker’s cough’, and any breathing conditions, such as asthma, should improve.

Hypnosis treatment also aims at addressing the subconscious motivations for smoking. These are often solutions for boredom, stress, loneliness, or the desire to fit in. While in the trance state the therapist repeats suggestions that offer alternative behaviors to smoking when those needs or situations come up.

Financial benefits: the average cost of a pack of cigarettes in the US is $6, which can add up over time. A pack-a-day habit will cost around $180 per month or $2200 per year. Quitting smoking could save as much as $22,000 over ten years.

Hypnosis can help by replacing things that in the past would trigger you to smoke with healthy alternative methods for quiting 

More youthful skin: smoking accelerates the aging of the skin. A smoking habit can leave the skin dull, dry, and prone to wrinkles, but quitting smoking can reverse these effects and allow the skin to receive the nutrients it needs. Over time, the appearance of the skin should also improve. 

Hypnosis aims to turn your negative outlook on smoking, into a Positive outlook and give you the "Will Power" to quit.
