Nicotine is the addictive drug in tobacco smoke that causes smokers to continue to smoke. Addicted smokers need enough nicotine over a day to ‘feel normal’ – to satisfy cravings or control their mood. How much nicotine a smoker needs determines how much smoke they are likely to inhale, no matter what type of cigarette they smoke.

Along with nicotine, smokers inhale about 7,000 other chemicals in cigarette smoke. Many of these chemicals come from burning tobacco leaf. Some of these compounds are chemically active and trigger profound and damaging changes in the body.

Tobacco smoke contains over 60 known cancer-causing chemicals. Smoking harms nearly every organ in the body, causing many diseases and reducing health in general.

Effects of smoking on the respiratory system

The effects of tobacco smoke on the respiratory system include:

irritation of the trachea (windpipe) and larynx (voice box)

reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages

impairment of the lungs’ clearance system, leading to the build-up of poisonous substances, which results in lung irritation and damage

increased risk of lung infection and symptoms such as coughing and wheezing

permanent damage to the air sacs of the lungs.

Effects of smoking on the circulatory system

The effects of tobacco smoke on the circulatory system include:

raised blood pressure and heart rate

constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature

less oxygen carried by the blood during exercise

‘stickier’ blood, which is more prone to clotting

damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)

reduced blood flow to extremities (fingers and toes)

increased risk of stroke and heart attack due to blockages of the blood supply.

Effects of smoking on the immune system

The effects of tobacco smoke on the immune system include:

greater susceptibility to infections such as pneumonia and influenza

more severe and longer-lasting illnesses

lower levels of protective antioxidants (such as vitamin C), in the blood.

Effects of smoking on the musculoskeletal system

The effects of tobacco smoke on the musculoskeletal system include:

tightening of certain muscles

reduced bone density.

Effects of smoking on the sexual organs

The effects of tobacco smoke on the male body include an increased risk for:

lower sperm count

higher percentage of deformed sperm

genetic damage to sperm

impotence, which may be due to the effects of smoking on blood flow and damage to the blood vessels of the penis.

The effects of tobacco smoke on the female body include:

reduced fertility menstrual cycle irregularities or absence of menstruation

menopause reached one or two years earlier

increased risk of cancer of the cervix

greatly increased risk of stroke and heart attack if the smoker is aged over 35 years and taking the oral contraceptive pill.

Other effects of smoking on the body

Other effects of tobacco smoke on the body include:

irritation and inflammation of the stomach and intestines

increased risk of painful ulcers along the digestive tract

reduced ability to smell and taste

premature wrinkling of the skin

higher risk of blindness

gum disease (periodontitis).

Effects of smoking on babies

The effects of maternal smoking on an unborn baby include:

increased risk of miscarriage, stillbirth and premature birth

low birth weight, which may have a lasting effect of the growth and development of children. Low birth weight is associated with an increased risk of heart disease, stroke, high blood pressure, being overweight and diabetes in adulthood

increased risk of cleft palate and cleft lip

paternal smoking can also harm the fetus if the non-smoking mother is exposed to second-hand smoke.

If a parent continues to smoke during their baby’s first year of life, the child has an increased risk of ear infections, respiratory illnesses such as pneumonia and bronchitis, sudden infant death syndrome (SIDS) and meningococcal disease.

Diseases caused by long-term smoking

A lifetime smoker is at high risk of developing a range of potentially lethal diseases, including:

cancer of the lung, mouth, nose, larynx, tongue, nasal sinus, oesophagus, throat, pancreas, bone marrow (myeloid leukaemia), kidney, cervix, ovary, ureter, liver, bladder, bowel and stomach

lung diseases such as chronic bronchitis and chronic obstructive pulmonary disease, which includes obstructive bronchiolitis and emphysema

coronary artery disease, heart disease, heart attack and stroke

ulcers of the digestive system

osteoporosis and hip fracture

poor blood circulation in feet and hands, which can lead to pain and, in severe cases, gangrene and amputation.
