Smoking cessation

[Ernesto]

While often very challenging, quitting smoking is one of the most important things smokers can do for their health.

Quitting smoking brings immediate health benefits that increase over time.
People who stop smoking may become irritable, anxious, sad, and restless; these symptoms decline over time.
Quitting smoking also provides health benefits for people around them.
Most smokers want to quit and have tried doing so without success.
Counseling and support in changing behavior, nicotine replacement products, and certain drugs double the chances of quitting smoking for good.

Smoking is harmful to almost every organ in the body, and quitting smoking brings immediate health benefits that increase over time. Within 30 minutes from the last cigarette, blood pressure and pulse decline and return to normal. Within 8 hours, carbon monoxide levels return to normal. After 24 hours, the chance of heart attack declines, and within 3 years the risk of heart attack is similar to that of people who have never smoked. Over time, cancer risk decreases as well.
Most smokers who quit do so for health or economic reasons. About 70% of U.S. smokers say they want to quit and have already tried to quit at least once. Withdrawal symptoms are a major barrier to quitting (smoking cessation).

Quitting smoking improves the health and finances of those who quit and brings immediate benefits to those who are exposed to exhaled smoke and smoke emitted from the end of a lit cigarette. The Surgeon General concluded in 2006 that there is no safe level of secondhand smoke exposure. Someone who successfully quits smoking can become a role model and support to other smokers who want to quit. Quitting smoking can be challenging, but it is possible and evidence-based treatments are available.
