Effects of Smoking Cessation

Around 70 percent of all the smokers in the world want to give up the habit, because they know that smoking is bad for their health. If you’re reading this, you’re probably one of those people – and this plan should make it possible for you to achieve that gold.

Health Benefits

The immediate effects of smoking cessation include:

• Within 20 minutes, blood pressure decreases, pulse returns to its normal level
• After 8 hours, carbon monoxide levels in the blood return to normal, oxygen level increases
• After 24 hours, chance of heart attack starts to decrease; breath, hair and body stop smelling like smoke
• After 48 hours, damaged nerve endings begin to recover; sense of taste and smell improve
• After 72 hours, the body is virtually free of nicotine; bronchial tubes relax, breathing becomes easier
• After 2–12 weeks, lungs can hold more air, exercise becomes easier and circulation improves

Longer-term effects include:

• After 1 year, the risk of coronary heart disease is cut in half
• After 5 years, the risk of stroke falls to the same as a non-smoker
• After 10 years, the risk of lung cancer is cut in half and the risk of other cancers decreases significantly
• After 15 years, the risk of coronary heart disease drops, usually to the level of a non-smoker

Many of tobacco's health effects can be minimized through smoking cessation. The British doctors study showed that those who stopped smoking before they reached 30 years of age lived almost as long as those who never smoked. Smoking cessation will almost always lead to a longer and healthier life. Stopping in early adulthood can add up to 10 years of healthy life and stopping in one's sixties can still add three years of healthy life. Stopping smoking is associated with better mental health and spending less of one's life with diseases of old age.

Some research has indicated that some of the damage caused by smoking tobacco can be moderated with the use of antioxidants. Upon smoking cessation, the body begins to rid itself of foreign substances introduced through smoking. These include substances in the blood such as nicotine and carbon monoxide, and also accumulated particulate matter and tar from the lungs. As a consequence, though the smoker may begin coughing more, cardiovascular efficiency increases.

Many of the effects of smoking cessation can be seen as landmarks, often cited by smoking cessation services, by which a smoker can encourage himself to keep going. Some are of a certain nature, such as those of nicotine clearing the bloodstream completely in 48 to 72 hours, and cotinine (a metabolite of nicotine) clearing the bloodstream within 10 to 14 days. Other effects, such as improved circulation, are more variable in nature, and as a result less definite timescales are often cited.

All of this happens no matter how old you are, no matter how many cigarettes a day you smoke or how long you’ve been doing it for. It really is never too late to give up smoking, so why not make today the day you decide to stop?
