How do you smoke in your room without getting caught?

Your best chance would to be lock the door, open the window and just make sure the smoke blows out the window and doesn't blow back towards you into the house. You can also get the brown circular cardboard thing after you have used all the paper towels or toilet paper and stuff about four dryer sheets into the tube and when you exhale exhale through the tube. the smoke will smell like fabric softener. and will overwhelm the little bit of smoke coming off the bowl or blunt..... and towel under the door. hehe that brought me back to my teenage years. lol
