Combine that with the fact that you aren’t just putting it in your body but the body of anyone within breathing distance of you,

That’s part of responsible use. I’m ok with only letting smokers smoke in specialty ventilated & filtered areas. Easy for me to say, I don’t smoke. But if any adult wants to make an informed decision to, that should be their choice.

Put it another way, if cigarettes are legal then marijuana, LSD, MDMA, and a whole host of other drugs should be legal too.

I emphatically agree.
