False.This statement is not true in every way.
Secondhand smoke is more dangerous than firsthand smoke. This is because there
are no filters that are present in the air which makes the smoke directly enter
the lungs unfiltered. Smokers have a lesser risk because of the filter attached
to the cigarettes. These things are responsible for regulating the chemicals
(e.g. nicotine, tar) that go inside the body which secondhand smokers don’t
have. So if you are around smokers most of the time, you should start staying
away because you might be getting more smoke inside your body than your friends
who do smoke.
