Lots of people from economically developed countries continue smoking although they are aware of the harm they do to their health.

The half of the smokers who want to stop smoking have already tried to do that. For last 4-5 years the number of smokers reduced sufficiently. It is worthy of not that the aggressive promotion of tobacco goods does its “black deed” – the amount of youth that starts smoking reduces very slowly.

The curious fact – it is easier to give up smoking for a person with higher education that for that who haven’t finished school (correlation about 8%/3%).
