Setting - How long does weed smoke get out of a room

[snowfield]

hello. swim needs to be tus all the time. "tus" is a word widely used in the philippines meaning like, when the cops or other people come and swiy is smoking some dope, friends say "tus" and swiy automatically hides any evidence. maybe swiy can use that term. or can swiy suggest any tus words? sorry for swerving there. anyway, how long does weed smoke get out of the room smoke exhaled in the room AND the comparison of the smoke being exhaled outside the window, even the pipe slightly outside the window so any form of virtual smoke is seen fly away from the window. swim needs to know this because swim lives in a stupid missionary house for rehabilitation purposes for doing drugs
