In the last few decades, smoking and its effects on health and society have been examined at length. We have all seen multiple ads by the government enumerating the risks of smoking, every time you watch a movie there is a warning that warns of the harmful effects of smoking. In fact, cigarette packets now have to carry images of the cancerous effects of smoking. However, information on passive smoking is still vague, many people still believe that being exposed to smoke can’t be as harmful as smoking itself.

Today we are trying to examine passive smoking in more depth to get a better understanding of what its effects are and how deep do they go.

What is passive smoking?

Passive smoking is inhaling another person’s tobacco smoke. It is usually a combination of mainstream smoke exhaled by a smoker and smoke that drifts out from the lighted end of the cigarette or sidestream smoke. Passive smoking is a lot higher in families of smokers. However, everyone is at risk. Passive smoking doesn’t only mean inhaling cigarette smoke; it also includes pipes, cigars or hookah. If a person next to you or a family member is smoking, you inhale the second-hand smoke without realizing it.

Why is passive smoking considered more dangerous?

Passive smoking involves inhalation of harmful chemicals that are directly released from the burning end of a cigarette, in addition to the exhaled smoke by a smoker.  Since the cigarette’s burning end doesn’t have a filter it releases more toxins into the air. The combination of both types of smoke contains higher concentrations of cancer-causing chemicals. It contains smaller particles, which can easily enter the lungs and body cells and cause more harm. So, while the filter saves the smoker, the same isn’t true for the people around him..
