Yep, they will weigh composite dosage units and then charge the individual with the full weight as applied to the controlled substance(s). I've seen it done once many years ago to some deadhead ex-friends of mine that got popped with hallucinogens on thick paper dosage units.... pretty low regardless of how deserving the perp is. According to an attendee, his trial also did not allow the weight disparity to be presented at ANY time, despite repeated attempts including blurting it out to sow the seed at a minimum. Hey, at least they have our best interests at heart right ?

Edit: Just read Trampy's reply, makes a bit more sense now. Still, paper seems a bit questionable (do you spit the paper out, do you swallow it, etc.). Moot point but whatever, best to just not get busted for possession.
