What does "Cone" mean?
Definition: A cone is a style of joint that is wider at the end you light and narrower at the end from which you draw. Cones are easiest to roll using a paper crutch or filter on the narrow end, because they provide sometimes-necessary support for the paper to hold large amounts of weed. In Australia, "cone" is slang for bowl. In Europe, cone joints are widely used, but are usually rolled as spliffs (with tobacco mixed in with the weed).
