How do you hide the smell of marijuana smoke?

First off never burn insence to try and cover it up. While it does cover it up, to most that's an auntomatic sign ur smoking pot. Candles and oil burners can be helpful but wont completely cover it. Heres and idea Ive seen it used and it worked. In addition to candles and oil burners do this. may be a bit of a headache but it helps if ur serious about hiding the smell. use an empty carboard roll(from tp, paper towels, plastic wrp etc. In one end stuff a few(3 or 4) fabric softners(I recommend some kind that smells like or close to febreeze or air freshner.)
In the opposite end blow the smokethrough it will scent the smoke and the side stream(2nd hand) should be covered up by the candles. in addition to this close the vent in the room you in so the smoke smell wont drift to oher rooms or if u live in one other apartments. keeping those plug inb air freshners on hnd could be good to. And always make sure to spray your clothing before going anywhere.
