oh thats right, forgot that the RA has hours until 12am or some shit.
Check their work hours.
Toke at midnight carefree and shit and you'll never get caught.
However due to the poor typical structures of dorms and the space.. you'll probably stink up your place.
No choice but to cover the smell somehow no matter what.. but at least you'll smoke all chill and happy knowing you won't get caught which is much better anyway!
