what i do.

To get rid of the odour go to the supermarket and buy some spray, incense is a little too obvious, good if you are by yourself in that house but not good if you have suspicious/paranoid or both parents. Get the stuff that is advertise to kill odors because you want that not ones that cover it up.Also don't get something obvious like lemon etc you can get ones like mountain air or some crap.I got a can for about $4.00 and stash that away, because that will look suspicious esp if you are not renown for a clean room.

Wait until parent/parents go to bed.
Switch on a DVD or whatever on just in case so they wont hear a noise.
Open the window
Mull up.

Once you have finished pack away spray alot of the spray,then shut the window a bit wide open window on a cold night is going to look suspicious.After stay in your room and watch DVD or whatever don't go out too soon otherwise the smell will go out.

I was thinking of buying a fan heater so in winter i can get rid of the odour without suspicious and to warm up my room. :thumbsup:

Happy smoking!.
