"How many people do you want to kill before you can put down the cigarette in your hand..."

Addendum 1:

Do you know why secondhand smoke is more toxic than firsthand smoke?

This is mainly because first-hand smoke is also called "mainstream smoke". Smokers inhale it directly into their mouths, and the suction force makes the air flow. The burning temperature in the center of the cigarette can reach as high as 900°C. High temperature will cause some harmful substances to volatilize.

Secondhand smoke, also known as "sidestream smoke," burns naturally on cigarette butts at a relatively slow speed, with an edge temperature of about 200-300°C. The lower the temperature, the less complete the combustion, and more harmful substances will be produced.
