No, if you’re in an apartment complex, you think partying potheads won’t spread their smoke down the halls? It’s been smelled in larger and more open environments than that.

That you can smell it does not mean you are going to get high from inhaling the aroma of it. I can assure you of that, and if that's all you fear, lay this fear to rest and fear no more.

Yes, but if you’re subjected to it for an hour? Come on.

And as the tobacco ninnies state, it can’t be good for you, long term, putting that in anyone’s lungs. (I don’t care as much about that - I’m worried about SHORT-term effects; they can suffer with their emphysema years down the road if they wish.)
