Smoking and tobacco

Tobacco smoke contains many chemicals that are harmful to people who smoke and non-smokers. Of the 7,000 chemicals in tobacco smoke, at least 250 are known to be harmful and 69 cause cancer.

Nicotine is the addictive drug in tobacco. After you’ve been smoking for a while, your body gets used to nicotine and relies on it to feel normal.

Smoking harms nearly every organ of the body and can cause 16 different types of cancer.

Smoking can also cause many other health issues, such as:

• asthma
• heart and blood circulation diseases
• lung diseases
• eye diseases
• dental diseases
• diseases of the stomach, gut and bowel.

Smoking can harm your immune system, which means you may get sick more often and take longer to recover than non-smokers.

Learn more about the health effects of smoking and tobacco on the Australian Government Department of Health website (external site).

Being exposed to other people’s tobacco smoke (known as second-hand smoke or passive smoking) is also harmful to health, especially for babies and children, pregnant women, and people living with chronic health conditions.

Second-hand smoke refers to the smoke from the end of a burning tobacco cigarette and the smoke exhaled out by the person smoking.

When second-hand smoke is inhaled by non-smokers, they are also breathing the same harmful chemicals as a person who smokes.

• respiratory diseases (such as asthma, bronchitis, and pneumonia)
• heart attacks
• developing type 2 diabetes mellitus
• infections
• plaque build-up in arteries (which can cause strokes and dementia).

Non-smokers can also experience eye, nasal and throat irritation, a cough, wheezing and shortness of breath.

Quitting smoking has major health benefits at any age, even if you already have an illness caused by smoking. The moment you stop smoking your body begins to repair itself almost straight away and you reduce your risk of developing serious health issues and diseases caused by smoking.

It is never too late to quit. Quitting smoking is one of the best things a person who smokes can do to improve and protect their health.

Even though withdrawal symptoms can be hard, remember they are a good sign. They show your body is adjusting to being free from the chemicals in tobacco smoke.

Research shows, in the long term, the average body weight of ex-smokers is similar to people who have never smoked.

Quitting smoking saves you money. If you smoke 20 cigarettes a day, you can save over $12,000 in a year if you quit smoking. Use Make Smoking History’s Quit Savings calculator (external site) to see how much you can save.

Quitting smoking is the single best way to protect family members, coworkers, friends and pets from health risks associated with passive smoking.

Smoking during pregnancy is known to effect babies even before they are born. There is no safe amount of smoking. Stopping smoking before or during pregnancy will give a baby the best start to a healthy life.

The placenta and umbilical cord play a vital role during pregnancy. Smoking reduces the amount of oxygen available to the baby through the umbilical cord. This makes the baby’s heart beat more rapidly and increases overall stress on its developing body. Smoking can also reduce the flow of blood through the placenta, which limits the amount of nutrients that feed the baby.

Smoking increases the risk of ectopic pregnancy and miscarriage, delivering a premature or low birth weight baby, or having a stillbirth.

There is also a strong link between Sudden Unexpected Death in Infancy (SUDI) and smoking during pregnancy and after birth.

A doctor, midwife or obstetrician, or Quitline (13 7848) (external site) can help support to quit smoking before or during pregnancy.
