it took my I smoked in my room all weekend while my parents were away and it only took a day to get all the smoke out. but if you wanna do It I say smoke at from 3 till 4 30 that way you can smoke for 4 20. Then while you're high try and get the smoke out.

Open the window and door. turn your ceiling fan on and spray oust or whatever you have cologne anything. Then just keep spraying shit every couple of minutes. If you have carpets run a vaccum. cause it'll make the room smell like it just got vaccumed.

A good way to test and see if the room still smells is by walking in to it. If you smell it then someone else will.
