When I smoke a joint I take extra smell precautions. I'll change my shirt and run water through my hair (the smoke clings) as well as eat some mints.

You don't need visine. If your eyes get red, just rub water into them. Works like a charm.

My favorite way of smoking, though, is to come home after a long day at school (I get home at like 6:45--it's a long fucking day), hurry up to the shower, lock the door, turn the water on so it sounds like I'm showering, and then blaze.

After that, you can take a real shower and get rid of the smell.
