while in the military, in the barracks we would put a towel down to seal the bottom of the door and we'd duct tape the cracks all around the door. you'd be sitting in your room and hear this ripping sound from somebody opening their door. not very stealthy but it worked. you couldn't smell reefer outside of the door. we never thought to check the windows. lol...that's an affirmative... It's smoke, it will seep through anything porus, and squeeze through any crack... you can use some weather strips to seal the interior, but it's going to smell...
...my advice - go to higher ground, and maybe even the attic or rooftop if you are worried about neighbors... if going up isn't an option, then try masking it behind lavenders, honeysuckle, jasmines, etc or have some heavy fragrant candles burning...
