If you smoke a blunt you will smell like a blunt no mater what you try to do for a while.
i f you use a pipe just air you or the room out, or you could smoke out side and be smart. I hate tokeing in peoples rooms that have parents that aren't cool with it. hiding it up with fabreeze makes them suspicious.
roast a bowl while having the shower shower on covering the cracks of the door and having the vent on. I do this a lot. My friend was at his house doing this and all the smoke ended up going out his window into the neighbors house and he heard a woman complaining to her husband and wanted to call the police. all ways be carful about where the smoke is going.
or "hawaiian hotbox". I recently did this with some buddies on a band field trip hahah. we just shoved a towel under the door in our hotel room's bathroom, put alot of shampoo in the shower and cranked the heat up all the way. works like a charm, clothes/hair don't smell either.
i smoke on my friends porch all the time his other neighbor even walked out on us and waved haha. The other neighbors are like 40 and all the bong smoke was going out the window into the neighbors house lol.
i trained a german shepard to walk around with me and bark when he smells something. but i trained him to like weed so he doesnt bark when he smells it. when people are like "do i smell weed?" i just look at the german shepard and say since the dog doesnt smell anything, nothing smells. and then the other guy is like okay.
Take a toilette paper roll and stuff it with bounce sheets. Blow out your tokes through that. Helps alot. Also can just put some holes in the end of a waterbottle and stuff it with bounce sheets and do the same. Works wonders
Sploofs, Ozium, Fabreeze, but nothing protects against that super sticky icky. I sealed off my bedroom door, had a fan blowing OUTSIDE to pull smoke out, used sploof, had fabreeze sprayin and a couple people smoking cigs, walked down stairs for some Arnold Palmer and the first thing my roomate said was "it smells like a fucking skunk died in here"....woops
