for dorms.

I'd say a key factor to any indoor smoking endeavor is Febreze air effects. It's febreze for the air for fuck's sake. I was never caught in the dorms once, pretty much thanks to febreze air effects.

Special thanks go to:
controlled air flow via a window box fan,
and either a fan by the door pointed at the window to control the air or a towel.
and of course a zoob tube.

if desperation hits, put duct tape over every crack on the door to make a permanent air tight buffer. It'll be noisy and weird when you open it but it makes your room air tight.

always check the air flow from the door with a lighter before the smoking commences. Flow is vital. If all the air is being sucked into the hall, there's no point in even trying.
