What is the methods can make one abstain from smoking?

i have never let a person who smoke stop his smoking. and i will take a try . if he stop the smoke i will tell you. if you want him stop smoke , he will stop smoking. and you should stay with him every minute .and see whether he is smoking.

I would suggest that a habitual smoker realizes firstly that he/she is an addict, then join a self-help group to get him to quit the habit permanently, but slowly. It's not easy to quit smoking instantly, but with a lot of support from people and family members would help him/her overcome the habit.
