all i know is i used to smog up my apartment a couple times a day and anyone who came inside that didnt smoke weed, would say damn smells like pot in here???then give dirty looks.....and i had an ionic breeze, can of ozium lime smelling shit,and febreeze as well as scented candles.... and non smokers could still smell the weed.....i say smoke outside, or try to open windows if you can
