It's actually quite beneficial for the lungs. Edit- thanks for the downvotes people who can't read/research (the cool thing about science is it's true whether or not you believe it)

Burden of proof.

Usually when one makes a claim, they provide evidence to support what they are saying. I understand it’s easier for you to take the time to accuse users of being illiterate or lazy than support your position.....but it’s not their responsibility to investigate and verify your claim. (Keep in mind I’m not speaking on the nature of or agreeing/refuting your claim).

It’s more constructive for the discussion if you share the science to support your claim, instead of bitching about downvotes.
