I am addicted at cigarette and want to come back from it. but i can not leave cigarette! please help me.

There are many ways: to stop smoking, but they all MUST start with your decision to do it. If you truly believe you can never stop smoking cigarettes, then you won't. The quit rate ranges from 3-5% with cold turkey quitting up to 40% and even better with the combination of Chantix and a smoking cessation program. Nicotine replacement therapy with patches, gum or lozenges is where I would start. Talk to your chemist.

Cold turkey.: As far as quitting without any nicotine replacement, the cold turkey method is great. But plan it ahead of time. Pick a quit date in advance, maybe a meaningful date like a birthday or holiday, and gather people who are aware of your attempt that you can call upon for moral support if you start to falter. Good luck!!
