The ill-effects of smoking cannot be emphasized enough. We know how harmful it is not only to the smoker but also to the person who receives second-hand smoke.
I know of people who tried to quit smoking. There were those who succeeded and are now free of that unhealthy habit; others have quit for a few months, only to go back to their vice again; and then there are others who have come up with alibis to justify why they cannot quit the habit.
I read that the best way to quit smoking is to do it cold turkey. However, not every person is strong enough to say goodbye to cigarettes. For others who, at least, have the desire to quit but are too addicted to the substance, they resort to aids like nicotine patch, acupuncture, nicotine gum, lozenges, tablets, even hypnosis. Recently, we have seen in the market 'smokeless' cigarettes which are said to taste like cigarettes, look like cigarettes but are not really cigarettes. They are called electronic cigarettes. The health issues on the user is still debatable but people around smokers who are otherwise subject to second-hand smoke may be benefited from this new product because of the absence of smoke.
