This thread is a joke right? A person who has never smelled pot and hippies inviting you to live in a meth lab?
Nobody with a meth lab wouldn't shoot you for coming near the house.
Pot? These days has become so potent it all smells a bit like a skunk. I don't smoke (well maybe once a year or so) but my brother does and it all has that smell.
Try to relax - if it's pot is it really that big a deal? If you don't want to be near it then move - but don't panic. They won't get the munchies and eat you.

Though they may ask for a ride to get fast food.
