Can secondhand smoke cause cancer?

You can work out daily and eat perfectly, but breathing in secondhand smoke will still damage your lungs and can lead to cancer. It is highly toxic. Try to train in clean-air zones and avoid hanging out around people while they are smoking.

Back in our days, people used to smoke everywhere—buses, offices, homes. But now we know better, and the link between secondhand smoke and cancer is very real. Don't worry if you had minor exposure in the past, but definitely try to avoid smoky places from now on.

It definitely does. I read a lot about this because my dad used to be a heavy smoker, and passive smoke is basically like smoking yourself. The risk of lung cancer is real, so I had to strictly ask him to smoke outdoors only.
