Because the smell is slowly making it's way into my house I've now had to give some thought to what to do about it. At some point I will need to talk to the source, or the owner of the house who lives in Maryland (I think). I was hoping that the build up would go away as the weather got colder, because I would smell this stench when a visitor would hang out in the basement stairwell smoking or opened up the basement door when the occupants were smoking away. The occupant hosts get togethers at least once a week or several times a week where he and his friends sit out in the back. The noise was one thing, but the smell, just makes my back yard unusable.
Have I called the police? In the past we called the Fire EMS because one time the strong smell got into the house. By the time the firemen arrived, the smell had gone. There was that time when one of the occupant's guests was dividing up pot in the back yard into smaller baggies, but by the time I could figure out what was going on the guest had a "legal" amount of marijuana (or marijuana looking like stuff) that he was mixing with an unknown white-ish pebble like substance.
Yes, I have to get around to speaking with my neighbor the occupant when I run out of candles and air freshners.
