It sounds more likely they would like it to be illegal for one to force others to be subject to second hand smoke.

Correct. As I wrote in my earlier comment, I have zero problem with people choosing it for themselves, as long as it's kept personal and I don't get opted in to anyone's smoking choices.

Ah I see.

I feel that it's unreasonable to equate second hand marijuana smoke with second hand tobacco. It's really hard to consume weed to the same extent as tobacco, so the smoke is in much lower quantity.
