**Considering the Issue of Secondhand Smoke from Tobacco** Although the term "secondhand smoke" is often heard, surprisingly few people may understand its exact meaning, so let's clarify it. First, "tobacco smoke" can be classified into three types: 1. Mainstream smoke: The smoke inhaled directly through the tobacco. 2. Sidestream smoke: The smoke that comes from the burning tip of the tobacco. 3. Exhaled smoke: The smoke that comes from the smoker's breath after smoking. Many people might mistakenly think that sidestream smoke refers to "the smoke that the smoker exhales," but in fact, sidestream smoke is the smoke that comes from the tobacco itself. *Secondhand smoke refers to inhaling either or both of the above two types: "the smoke that comes from the tobacco" and "the smoke that the smoker exhales."* Incidentally, it is noted that sidestream smoke contains a higher concentration of harmful substances than mainstream smoke, which means that non-smokers may be inhaling a higher concentration of harmful substances than smokers. From the perspective of non-smokers, this is a very troublesome issue. > For more, click here https://www.ergojapan.co.jp/smokeclear/column/898/
