Next door neighbour started smoking pot outside, in between our houses a few months ago. I first noticed that skunky smell in our garage. I didn't think much of it, as it was barely noticeable - I thought maybe it came from a bunch of empty beer bottles.
But then it came back on a daily basis. I'd be outside, on the other side of the house, reading and that stinky smell would interrupt me. And I
hate the smell of pot. Soon enough, what was an isolated, occasional incident became regular, everyday, all through the afternoon.
We eventually got tired of it and confronted him. He said he'd been under a lot of pressure, apologized and said he'd find another place. So he started smoking in his garage - which changes nothing because his garage door is always half-open and our houses/garages are maybe 15 ft from another.
Result - I can't spend an hour outside w/o having to put up with that frickin' smell and our garage constantly smell pot.
One odd thing I've noticed in all my years is that, quite often, people who are already pretty relaxed tend to love pot, while people who'd probably need to mellow out a bit will opt for coke and speed...
