Can a novolog flexpen be used for illicit drug use?

Any medicine delivery device can conceivably be used for illegal drug use, the Novolog Flexpen is no exception. However since it is prefilled and requires separately acquired needles specifically designed for the flex pen, it's illicit use would probably be more trouble than it's worth. Besides, you'd have to have a syringe to refill the built-in vial, as well as figure out how to reset the internal plunger. Again, more trouble than it's worth.
