Tobacco use is one of the leading causes of preventable death and illness, with an estimated 443,000 people dying prematurely from smoking or secondhand smoke each year. Not only do smokers harm themselves, but they also harm others around them through secondhand smoke exposure. Children are especially susceptible to health issues from secondhand smoke. While many people find it difficult to quit due to nicotine addiction and social/habit factors, going cold turkey is the most effective method for those who successfully stop smoking.
