What is secondhand smoke
Secondhand tobacco smoke is a mixture of the smoke given off by the burning end of a cigarette, pipe or cigar and the smoke breathed out by smokers.
Secondhand smoke has more than 4,000 different chemicals. At least 250 of these chemicals are known to cause cancer or be toxic, including:
Breathing secondhand smoke is also called passive smoking.
Secondhand smoke can be harmful to:
Smokers are also more likely to have a fire in their home.
The way that smoke stays in the air and moves from room to room means that the risks on you and your family remain.
Smoke in your home
There's no hiding from secondhand smoke in your home.
If you smoke at home it can quickly lead to children breathing in harmful levels of air pollution. Worse than those found on the streets of big polluted cities.
Secondhand smoke can move invisibly into or out of open windows or doors. Even when a cigarette is stubbed out the invisible poisons in the smoke can stay around for up to 5 hours.
Smoke in your car
There's no safe level of smoking in a car even when your windows are down. If you smoke in your car, the pollution levels can be 35 times greater than levels the World Health Organization consider safe.
Since 1 September 2015, it's illegal to smoke in a vehicle carrying children and young people under the age of 18. You could be fined up to £2,500.
Smokers can also lose up to £2,000 when they part-exchange their car at a dealer.
Refer to restriction on smoking in motor vehicles for more information about this law.
Risks on babies and children
Tobacco smoke can harm your baby even before they are born. Pregnant women exposed to secondhand smoke are at higher risk of having:
- premature babies
- low birth weight babies
Secondhand smoke also has a number of bad effects on children's health. Children and infants are more vulnerable to tobacco smoke than adults because they have smaller airways, breathe faster and their immune systems are still developing.
If your baby or child is exposed to secondhand smoke they will be at higher risk of:
- sudden infant death syndrome (SIDS), also known as cot death
- breathing problems, coughing, wheezing, croup, and chest infections
- having asthma symptoms all year round. Exposure to secondhand smoke doubles this risk
- having meningitis or middle ear infection, also know as glue ear
Adult smoking can have serious impacts on children. Children with parents or carers who smoke are 4 times more likely to start smoking when they are older.
Risks on adults
Short-term effects on adults from exposure to secondhand smoke include:
- eye and nasal irritation
- sore throat
Long-term effects include increased risk of:
- coronary heart disease, with a risk increase of 25% to 30%
- lung cancer, with a risk increase of 20% to 30%, and other cancers
- stroke, with a risk increase of 20% to 30%
- chronic obstructive pulmonary disease (COPD) and other breathing problems
Breathing in secondhand smoke makes the blood stickier, meaning there's an increased risk of blood clots forming, even with brief exposure.
A clot can block blood vessels and cause:
- heart attacks
- heart failure
How to protect yourself and others
You may already take some steps to protect your family, such as opening windows or smoking in a different room. This might get rid of some of the smoke, but there is no safe level of exposure to secondhand smoke. Even short exposure can be harmful to those around you.
The best way to protect those you care for is to make your home completely smokefree. Take any smoking outside and close doors and windows behind you.

Secondhand vapour from e-cigarettes or vapes
The long term effects of vaping on health are not yet known as research is still developing.
It's recommended that you do not use e-cigarettes in a home where children live. However, if you're using an e-cigarette means that you have a smokefree home, this is likely to be safer than smoking.
If you choose to use a vape to stop smoking you can find support and advice on Help2Quit stop smoking.
