The question was how this person is able to function not what other environmental factors play a role.

Growing coffee also has an impact on the environment, I would argue much more than growing weed - conveniently out of sight for the consumer. But that’s not really my point here.

Just so we're clear, you're talking about weed smokers like the GP?

You've gotten passively stoned?

It’s hard to do but if you would be in a locked room with a bunch of lit joints going around you probably can get moderately passively stoned.

That's a bit different than the public nuisance claims.

I suppose you'd want to avoid a cannabis sauna if you want to avoid getting passively stoned.

Yea I wrote it more to illustrate that the “getting passively stoned from smoke on the street” argument is kinda ridiculous
