when I smoked crack, I used the foil to wrap the crack up in. It comes in little rocks, and most dope boys sell them by the rock, so you put the crack in the foil to "protect" it from crumbling. My cigarette packs NEVER had foil.
I would also take the plastic "bag" off the cigarettes for the same purpose, but it made too much noise when I was trying to hide it from the cops by rattling.
Sorry, but this doesn't sound good.
Hugs and prayers!
