> Was I an opiate user? Given that they were prescribed to you, "yes" would be a reasonable assumption, barring you able to provide evidence introducing reasonable doubt (e.g. "I still have every pill I was ever prescribed"). In any case, "was" is the key word. You were given a prescription for a finite number of doses, whereas usually a medical marijuana card is more indefinite.
