Who could have known that smoking chemicals could lead to respiratory disease?

  It's not smoke, like in a cigarette (from combustion), it's vapor from heating a liquid into a gas (boiling).

      You do that every time you breathe anyway, unless you make a habit of breathing argon or the like.

      You do that everything you stand in front of a BBQ or a camp fire. Exposure alone doesn't guarantee a harmful effect.

        If you spend every day in front of a camp fire, things aren't going to go well.

        Camp fires do produce harmful particles and I'm pretty sure that BBQs do as well. Purposefully breathing the smoke generated by either of them is a bad idea.
