Re: howto keep the smoke in my room
I think he means keep the smoking from spreading to other rooms. If so, you could shut the door (obviously lol) and place a towl/blanket/shirt or something at the bottom crack of the door to keep the air from going out. You can also open a window and possibly even place a fan facing out the window to keep the air circulating out instead of in. A good way to test this is to grab a lighter, light it and go around the cracks of your door and see if the air is moving the flame towards or away from the door, or even no movement at all.
Hope this helps =]
