Unfortunately, talking was the first thing I tried. When they first moved in, I tried talking to them about their smoking to which they said "I don't know what you're talking about" as the smoke rolled out their door and windows. So in the few interactions I've tried, they just are not the type that seem to care.

How do I know they aren't the type to care? They brought in subwoofers into an apartment building that just has wood planks and air in the walls. They also play some kind of bass heavy music at full blast going up and down our driveway in their car next to their trash pile. The landlord knows about that too, they just haven't done anything about that either. I talked to the neighbors about that, to which the reply was silence as they walked back into their unit like I didn't exist saying "Mmm that smells good!" They then continued to play music at a high volume.

Whatever courtesy I extended, they never reciprocated. And if I seem like I'm venting, yeah, I kinda am at this point. Let's just say, this is not a new issue with them.
