You say he was a Sheriff's Deputy. You're lucky. Most SO's in CA do not do DUI (or general traffic) enforcement as they sign MOUs with the CHP for that. So, the deputy may not have been all that confident with the laws concerning drugged driving.
Hopefully you grow out of this need for dope, or, since I doubt that you will heed any advice based upon the real risks of marijuana you will at the very least you will keep it at home next time.
