Vaporizing pot still smells like pot and do you guys realize how many other chemicals you're getting with that (even the clear bulbs)? Do yourselves a favor and build a doob tube (TP tube with dryer sheets in it), put a fan in the window and invest in some Ozium. You might also consider smoking in the bathroom (unless you have common bathrooms), they usually have industrial vents in there (might need to be cleaned), feel if the air is coming in under the door. I know it's a hassle but your lungs (and your brain) will thank you!
