This thread is about getting rid of the smell from a room not how to eliminate smoke odour whilst smoking, the risk of getting caught has to be taken into consideration, whereas this thread is about getting rid of the smell after you smoke, I'm sure you can use a doob tube but In my own opinion it's a bit risky that's all.

Please feel free to explain the doob tube, because for some people it might not work and it may jeapordise the whole session if people are present in the home and catch you
