yahhhh i like to turn the a/c on when im hotboxing, i got 2 12s in the trunk and we be bumpin and you can see the smoke move lol
spray a bit of ozium or febreeze after a hot box and just it air it out. unless you drive a car with that very thin soft fabric you don;t really have a problem. even w/ a car with the fabric i just described the smoke smell will only last a couple days depending on how wrecked you got. unlike cigs weed doesn't have nasty additives and chemicals so unlike cigs weed smoke is a lot less nasty and eventually, at least in my experience, the smell will go away.
don't a lot of those air freshener products have suuuuper harmful ingredients? I think i was reading somewhere about that - will have to look into it again and repost to backup my claim unless somebody knows what i am talking about....
