if you can find a room nobody EVER goes in just smoke in there. luckily for me that's my room. after a few days it'll fade into a hamstercage smell, then a couple days after that it should disappear. another option is to take small-medium hits, and hold it in until no smoke comes out. that'll get you fucked up. in fact, you should practice holding your breath all the time so you can hold bigger hits longer.
