Ultimately, it's a question of the proofs. Everyone involved is presumed innocent until proven guilty beyond a reasonable doubt. Each "friend" has a right to council, should exercise that right, and needs their own lawyer for their particular circumstances. I would never recommend that co-defendants in a pending criminal matter be represented by the same attorney because it is arguably a conflict of interest. Speaking generally, there is a lesser-included charge of "use" of marijuana.
