I find different methods of smoking have different levels of smoke output. Smoking a joint would be way worse than hitting a pipe, because it would smoke constantly into the air.

I find the least smoke escapes the champer or your lungs if you use a small waterfall/gravity bong.
Although the apparatus is a little cumbersome, this technique will cutdown on your smelly emissions, and at the same time conserve your weed.

During the lighting process less than 1% of the smoke will be outside the chamber, and depending on how long you hold it in your lungs and where you blow it, as little as 5% of the total smoke will be in the residence air to smell.

Using the dryer sheet tube method should make this smoke smell almost negligible, and completely deniable.

But seriously, just smoke outside, and don't get your roommates in [censored].
