As much as I fully endorse recycling in this way, in America, even though smell isn’t enough to convict you, it’s still enough to get dragged through the court systems until your life is beyond wrecked.
Anyone can walk by an apartment/trailer, smell it, and call the cops on you. Once that’s done, there’s nothing to stop them from assuming your neighbors word over your own. Especially if it turns out they were right and the cops find cannabis in your home.
Lol wondering the same thing myself now
