As someone said above, just turn on the shower(you don't even have to shower) and blow the smoke into the ceiling fan/air duct thing.

Not only does the fan take care of most of the smoke, but the steam from the shower helps to eliminate odor as well.

I do it in my own house sometimes even with my parents home. And my parents sent me to therapy when they caught me with a half O.. so you can see how much I trust this method
