AWOL,
I have been employed by MediCann for 3 years. These cases almost always get thrown out. The Highway Patrol will recognize a MediCann card, what you had was a jerk cop.
If the officer confiscated your paperwork, and your card, you should immediately get into your nearest MediCann office and get a re-write, and card. You can also contact our call Center 866.632.6627 and ask for the Card Department, they should be able to mail one out to you.
Honestly I do not believe that you have anything to worry about, other than a big headache and a big waste of time.
Sorry about your car,
MediCann Admin
