I smoke inside my closet. And, I exhale into a pillowcase, which contains the smoke. Once I exhale, I close the closet door till the smoke inside dissapates. The weed smell doesn't even enter my room, it just stays in the closet.

Here's a link to a thread where I explained in even more detail how I keep the weed smell away.
