As long as the room has a window you are ok. Make sure to use a pipe to minimize the smoke. Take a paper towel roll and stuff each end with a fresh smelling fabric softener. Make sure to use a paper towel roll not a tp roll because the extra lenght allows for an extra filter.
Just exhale all hits through the tube toward the window and you should be just fine! As soon as you light the pipe cover the top to stop it from smoking.
Oh and put a towel on the baseboar of the door. You should be good.
Good luck!
