Today i smoked a joint and a bunch of bowls in my room, my rents are back on sunday night i had a fan in there with the window open. But when i left it still smelt of weed and it was starting to spread throughout some of the house. I left three windows open. How long will it take untill it doesnt dank???
You'll be fine dude, spray air freshener if you're a little paranoid, that always puts my mind at ease when I smoke and I'm worried about the smell.
Incense only if you normally burn it with them around, definitely use a sploof in the future; just a couple dryer sheets stuffed in a toilet paper roll, smoke through a fan facing a window. Holding your tokes longer also means less to exhale
