incense.. stoners greatest accessory... get the good ones tho i like the ones you can get at headshops or this wiccan store that used to be in syracuse that you put together a bag of them.. they burned for a long time and smelled insanely good and covered up the weed smell amazingly, i was burnin incense all night this one time when the cops showed up and they didn't know anything

air conditioners are pretty sweet.. all the smoke gets sucked into mine.. or open a window and use a fan

also cigg smoke covers up weed smoke and vice versa
