The Ultimate Winner
I'm throwing this out there because I have no answer, just going by what I have learned.
You cannot fail a drug test breathing in second hand marijuana smoke.
Knowing this, I question second hand cigarette smoke.
I have never smoked either and have stayed away from those that do either, so I am not real sure what the difference would be.
You can fail a drug test by inhaling 2nd hand marijuana smoke. That's the most common defense.
For me, the argument about 2nd hand smoke comes down to this question; Would I rather live in an authoritarian utopia with pure air, or would I rather live in a free world where I might have to tolerate a little smoke? I prefer the latter.
My main source of heating is wood. I've always had a wood stove. Not only that, but I run a dirty 2-stroke chainsaw to cut the wood. It's dirty. I get that. But that's outweighed by the positive ideal of being able to produce my own heat source.
I was told by a DOT physician that 2nd hand smoke would not create a positive test for marijuana, unless you are directly in front of the person exhaling and they were exhaling in to your mouth and even that is questionable.
