well when i smoke in my bathroom sometimes i notice that using bowls make it smell a lot less then blunts/joints. Open all your windows, make sure that you won't be disturbed at random (like waiting til your rents go to sleep or w/e), if you got a fan turn that on and spray the room a couple times just to hide the odor a bit. Or you can just try to go outside and smoke out there its real peaceful especially at night time.. hope that helped
