Quitting Smoking Timeline
When quitting smoking, there are numerous physical and emotional effects the body experiences. These effects are both short-term and long-term.
Short Term Effects
However, with this absence comes greater symptoms of withdrawal, which is why it is good to have something like nicotine gum or a vaporizer around to help manage your cravings.
- The short-term effects of quitting smoking begin within 20 minutes. Cigarettes contain ingredients and produce chemicals that speed up your heart rate, and also raises your blood pressure. These effects also occur when using even the best vape, since most, but not all, e-liquids contain nicotine, which is responsible for raising your heart rate. According to the CDC, within 20 minutes of not smoking an analogue cigarette, your heart rate will already begin to drop down to normal levels.
- Within two hours of not smoking, your heart rate and blood pressure will have returned to almost completely normal levels. Your peripheral circulation may also begin to improve during this time. This means you may begin to feel warmth in your fingertips and other extremities. This is due to your circulation improving. However, during this time you may also begin to experience some of the adverse effects of quitting smoking: withdrawal symptoms. These symptoms may include anxiety, increased appetite, irritability, sleeplessness, and intense cravings.
- After only 12 hours of not smoking analogue cigarettes, your blood oxygen levels raise to near normal levels. As stated by the CDC, carbon monoxide is released from a lit cigarette and inhaled with the smoke. At high levels, carbon monoxide is considered to be toxic to the human body. Carbon monoxide also bonds effectively to blood cells, prohibiting them from bonding successfully with oxygen. This can lead to serious cardiovascular complications. After 12 hours of not smoking, these carbon monoxide levels decrease, allowing your blood cells to once again bond effectively with oxygen.
- Since the risk of heart attack is 70% higher than those who do not smoke, after 24 hours the risk of heart attack begins to decrease.
- The sense of smell and taste rely on nerve endings. Smoking deadens these nerve endings. However, according to the Cleveland Clinic, these nerve endings begin to regrow within 48 hours of not smoking. This means that your sense of smell and taste will begin to increase, allowing you to experience more flavor and aromas.
- Approximately three days after quitting, the nicotine levels in your system will have been depleted. However, with this absence comes greater symptoms of withdrawal. Increased tension, cravings, irritability, and other symptoms may be strongly present. [There are several methods used to combat these symptoms which will be addressed at the end of this article.]
- After two to three weeks after quitting smoking, numerous regenerative processes begin to take place in the body. Some of which are very noticeable. According to the American Heart Association, your lung capacity and performance will begin to regenerate and improve, as will your circulation. This will allow you to perform intense activities such as exercising, running, and various other physical activities that rely on endurance and stamina.
- Between one and nine months after quitting smoking your lungs dramatically begin to repair themselves. One of the adverse effects of smoking analogue cigarettes is the damage to the cilia. Cilia are the small hair-like organelles which assist in reducing your risk of infections by pushing mucus out of your lungs. The regenerative process your lungs undergo include the repair of the cilia. This increases the lung function and performance, as well as reducing the risk of infection.
Long Term Effects
- The risk for any type of coronary heart disease is much greater for a smoker. According to the CDC, approximately one year after smoking your overall risk for coronary heart disease decreases by half.
- Another primary adverse effect smoking has on your health is the constricting of blood vessels. The constricting of the blood vessels greatly increase the chance of stroke. A primary factor which causes this is carbon monoxide. Between five and 15 years after quitting smoking, the chance of stroke decreases to that of an average non-smoker, according to the CDC. This restorative process takes time, but results in an overall decrease in an ex-smoker’s mortality rate.
- The CDC further states that after 10 years of not smoking, the risk of lung cancer, cancer of the throat, mouth, esophagus, and major organs also decreases by approximately half that of a traditional cigarette smoker. Medical practitioners report that nearly 90% of all lung cancer-related deaths are a result of smoking traditional cigarettes.
Within 15 years of quitting smoking, nearly all of the restorative processes are complete. Your risk of heart disease is no greater than someone who has never smoked an analogue cigarette. According to the American Heart Association, on average, non-smokers live 14-15 years longer than those who smoke cigarettes. With restored lung function, circulation, and cardiovascular health, those years are spent being active and healthy.
