Oh, and there is smell, but you won't notice it (if you're using it). To others (in my example, my friend's parents) smell fresh herb. They (my friend's parents) said it smelled like we had a pound of bud laying out freely on a table, when in reality we just vaporized about a half gram to a gram...Needless to say, they were kinda pissed and confused when they came into the basement, finding us sucking the scent of fresh marijuana out of a wooden box plugged into the wall...
