What is active and passive smoking?

Active smoking is the act of inhaling tobacco smoke directly from a lit cigarette, cigar, or pipe. This type of smoking is the most harmful, as it exposes the smoker to the highest levels of tar and nicotine.

Passive smoking is the inhalation of tobacco smoke by a non-smoker. This type of smoking can occur when someone is in the same room as a smoker, or when smoke seeps into a room from another room. Passive smoking can also occur when someone comes into contact with clothing or furniture that has been exposed to tobacco smoke.

Passive smoking is harmful to non-smokers, as it can cause a number of health problems, including:

* Heart disease

* Stroke

* Cancer

* Respiratory problems

* Sudden infant death syndrome (SIDS)

Passive smoking is especially harmful to children, as they are more vulnerable to the effects of tobacco smoke. Children who are exposed to passive smoking are more likely to develop respiratory problems, such as asthma and bronchitis. They are also more likely to start smoking themselves.

The best way to avoid the harmful effects of passive smoking is to avoid contact with tobacco smoke. If you do come into contact with tobacco smoke, try to move away from the source of the smoke and get some fresh air.
