Many of those chemicals are poisonous and at least 69 of them are linked to cancer. In the United States, the mortality rate for smokers is three times that of people who never smoked. While the effects of smoking may not be immediate, the complications and damage can last for years. The good news is that quitting smoking can reverse many effects. One of the ingredients in tobacco is a mood-altering drug called nicotine. Nicotine reaches your brain in mere seconds and makes you feel more energized for a while.
But as that effect wears off, you feel tired and crave more. Nicotine is extremely habit-forming, which is why people find smoking so difficult to quit. Physical withdrawal from nicotine can impair your cognitive functioning and make you feel anxious, irritated, and depressed.
Withdrawal can also cause headaches and sleep problems. Over time, this damage leads to a variety of problems. Along with increased infections, people who smoke are at higher risk for chronic nonreversible lung conditions such as:.
Withdrawal from tobacco products can cause temporary congestion and respiratory discomfort as your lungs and airways begin to heal. Increased mucus production right after quitting smoking is a positive sign that your respiratory system is recovering.
They also tend to have higher rates of pneumonia and bronchitis. Smoking damages your entire cardiovascular system. Nicotine causes blood vessels to tighten, which restricts the flow of blood. Over time, the ongoing narrowing, along with damage to the blood vessels, can cause peripheral artery disease. Smoking also raises blood pressure , weakens blood vessel walls, and increases blood clots. Together, this raises your risk of stroke.
Exposure to secondhand smoke carries the same risk to a nonsmoker as someone who does smoke. Risks include stroke, heart attack, and heart disease. The more obvious signs of smoking involve skin changes. Substances in tobacco smoke actually change the structure of your skin.
A recent study has shown that smoking dramatically increases the risk of squamous cell carcinoma skin cancer. Smoking increases the likelihood of fungal nail infections. Hair is also affected by nicotine. An older study found it increases hair loss , balding, and graying. Smoking increases the risk of mouth, throat, larynx, and esophagus cancer.
The Polish researchers found that obese women showed the greatest risk reduction for current smoking OR 0. This same interaction works to increase the risk among smokers of developing osteoporosis, and reaching menopause earlier than non-smokers see Sections 3. Based on the average of data from —15 and —16 we can derive theoretical estimates that smoking may prevent the loss of about 16 lives from endometrial cancer in Australia annually.
Pre-eclampsia is a potentially serious condition in pregnancy in which the woman develops high blood pressure, fluid retention and abnormal kidney function.
Smokers are less likely to develop pre-eclampsia than non-smokers. A study using Swedish birth registry data on more than , births examined the effects of snuff use and cigarette smoking on pre-eclampsia risk and found that compared with non-tobacco users, light smokers experienced a one-third reduction in risk OR 0. There is also a suggestion that pre-eclampsia may occur less frequently in smokers because smoking is associated with a greater likelihood of preterm birth as well as other complications see Section 3.
As pre-eclampsia develops in the late stages of pregnancy, smokers are less likely to be exposed the pre-eclampsia risk period.
A study has estimated that if studies controlled for the risk of pre-term birth and other biases the effect of smoking itself on pre-eclampsia risk may be non-significant.
The prevalence of smoking is higher among people with psychiatric conditions. Smokers often perceive their smoking to be helpful in relieving or managing psychiatric symptoms, 48 and many mental health workers have traditionally believed that quitting smoking will exacerbate mental illness.
Some studies have suggested that smoking may be associated with a reduced risk of developing thyroid cancer, 51 , 52 particularly for women. Early evidence suggests a protective of effect of smoking for certain types of skin cancers.
There is some evidence that smokers 56 and users of smokeless tobacco 57 are less likely to develop aphthous stomatitis common mouth ulcers.

They may enrol you in a stop smoking clinic, or prescribe nicotine replacement therapy or stop smoking medicine. Nicotine replacement therapy NRT , anti-depressants and other medication have all been shown to help smokers without mental health problems to stop smoking and they may also be helpful for people with depression or schizophrenia.
NRT appears to be more effective when combined with a talking therapy. You could also consider e-cigarettes. Talk to your doctor, a pharmacist or a health visitor about which treatments might be suitable for you.
Individual, group or telephone counselling can help people to stop smoking. Talking therapies can help people change their behaviour by thinking and acting more positively. Many counselling programmes use the techniques of cognitive behavioural therapy CBT and social skills development.
Research has shown that CBT may be particularly effective in smokers with or without mental health problems. Removing all tobacco products from your home can help lessen some of the cravings of nicotine withdrawal. Learn to recognise your smoking triggers. Identify when you crave cigarettes, such as at a party or after a meal.
Most cravings only last a few minutes.

Drinking more fresh fruit juice or water, eating more high fibre foods and reducing caffeine and refined sugar in your diet can all help you cope with withdrawal symptoms. Many people who quit smoking will relapse at some point. Use it as an opportunity to reflect on what went wrong, learn about yourself and figure out what will help you be more successful in future.
