Well you guys have really made me all freaked out, talking about prison time and court cases.
You
should be freaked out about it. You've got a very serious issue that is compounded by the fact that those kids know the smell of dank bud.
You need to take a 'sick day' and resolve the problem immediately. Build a carbon filter - its cheap and easy. Good vids on youtube.
In the meantime, dont answer the door for ANYONE and tell your GF not to either. BTW, if the cops come knocking and you answer, they WILL claim they smell it. You've just given them probable cause for a search warrant.
You've got a nice little crop there... I wouldn't scrap it just yet. I highly recommend you add ducting through your wall or ceiling and exhaust outside ASAP. Pull all your exhaust air through the carbon filter and utimately vent it outside the house. As someone else mentioned, maintaining negative pressure in your grow room is critical. Everything you need can be had at your local home depot, or whatever. You can also save your cutouts to patch the holes with some joint mud when you're done. Its simple, its worth it, and you will sleep a lot better.
I run a couple big DIY carbon filters in my grow... One takes care of general room exahust and vents out into my backyard through what would appear to be a simple dryer vent. The other one pulls stinky air from my flowering sub-room through the filter, then through a 1000w hps light, and into an adjacent utility room where it ties into my HVAC exhaust ducting, through which it exits my roof.
I use this and a combination of other air fresheners, pucks, and sh!t.
I sleep pretty good.
Good luck!
