If you want to quit, you should.
Smoking can be hard to quit. However, we believe it is important that smokers who decide to quit realise they can, provided they have the motivation to quit and the belief that they can. Many smokers are said to be dependent on cigarettes, because although they know the real risks of disease involved they still smoke frequently.
However, millions of smokers have quit without any medical help and millions have modified how often, where and when they smoke in the light of differing social norms. In some countries, such as the UK, there are now as many ex-smokers as smokers.
Various ways have been suggested to help people quit, including using nicotine replacement therapy (e.g. patches and gums). While all these forms of assistance may be beneficial, the most important factors in successfully quitting are having the motivation to quit and the self-belief that you can do so.
