I have to disagree with SporesDirect. Smoke only in your room. It's probably the safest place. You could roll all your weed into joints and smoke them outside, but why waste all that weed and why risk getting caught smoking in public? Get one of those fans that you can put in your window. Seal the entire window around the fan and have it blowing out. Do not seal the cracks in your door or put towels under it. Why? Because you want to control the airflow in your room. You want the air to come in from the hallway, through your room, to the fan and out the window. When you turn your fan on you should be able to feel a breeze coming in from under your door. It is now impossible for anyone outside the room to smell it, since that requires air to leak out of your room into the hallway. If all the air is going out the fan, you don't have to worry about the smell. Take all your hits near the window and blow them into the fan. Cap your bowl when you're done. Try to keep the amount of smoke inside the room to an absolute minimum, especially if you have a smoke detector. Oh, and keep your door locked whenever you're toking. It's just common sense.
