These people don't know what they're talking about.

What you do is spray some Ozium (avilable at Kmart, Walmart, Internet, etc.)
and you'll be all set. That stuff works wonders with weed because it's glycol-ized
I guess.

I use Ozium all the time to cover up the smell, it smells good, kills bacteria,
and is meant for the air so you don't spray it and it just lands on the ground.
It actually looks like you are spraying a cloud of smoke out but it just mixes
really well and blocks pot smell well.

Also I use a window fan that I fit in my window blowing the smoke out the
window. This way even if my room smells like smoke, if you walk outside my
room you'll smell nothing. This is because the room is pressurized and no air
is really going into any other parts of the house. I'm always paranoid about
doing it on windy days though. Definitely try Ozium, I was hooked the first
time I gave it a try. :thumbsup:
