well depends. if i know my parents will be gone for another hour, then i usually have time to get it completely aired out. i start by shutting all the doors (unless they lead to outside) and open all the windows. next turn on a fan, and blow all the air out of the window. if you don't have a fan, a blanket being flown around works just as good. once that is finished, i try and cover up the remaining smell with a bit of fragrance. it's funny that you started this topic though, cause i'm in the process of airing out a room right now lol.
I haven't faced this problem anymore since i was about your age, but back in those days i used to burn some incense to prevent from getting busted.
incense is a must.. i agree. burn it whenever your in your room.. that way they wont get suspicious.. but keep doin the airing out ritual as well.. with that combination, ya cant lose.. unless of course your parents are old stoners,,then they already know what your up to.. an the incense thing should give them a laugh.. still id rather my kids room smell like incense than weed.. ya never know who may be dropping in...
something i have found that works very well is putting one of those fans that just plugs into the wall and putting it right up against the window. This way it will suck air out of the room and blow it out the window.
i heard someone on here once say burnt popcorn covers up the smell well. but that's if ur in a real crunch. i wouldn't really wanna smell that the rest of the night.
dude just make some toast lol. If I was smoking downstairs for some damned reason I'll just make some toast and the smell of toasted and possibly slightly burnt toast gets rid of any other smells in the house.
When im smoking and theres people around, I just go to my room, and use my doob tube. A doob tube is just a paper towel tube with a dryer softener sheet taped over one end and then 6 more sheets stuffed down into the tube. Blow smoke thru the open end and the smoke comes out smelling like lavender or whatever the scent is. When ur done air out the scented smoke and ur done. If u got like really paranoid parents like i do, keep a candle that has the same scent of the dryer sheets and then if they ask you why ur room smells like lavender u can say i just lit a candle.
Since we got busted because the neighbors narced on us, we've been smoking in the bathroom with the shower on. The water particles in the air catch the smoke and pull it to the ground as the bathroom cools down.
put a bowl of spaghetti sauce in the microwave. in my dorm room, but that's presuming u have a microwave in your room.
