Here's the deal, if you are a legal patient, then keep everything in the trunk. DO NOT CONSENT to a search, DO NOT ANSWER ANY ?S. You are not doing anything wrong unless you have done some kind of traffic infraction. In which case you need to ask them "why did you stop me". They can lie, threaten you, do what ever they want. But you do not need to tell them anything. If you feel as though the cop is not going to just write you a ticket and send you on your way, then ask him, "AM I BEING DETAINED". You also do not have to tell them you are a patient, and it is illegal for them to ask you why you are a patient, or ask anything about your medical condition. (If you do tell them that you are a patient) Make the fuckers do their job. If they want to blow a couple hours messing with you and trying to get a warrant, in the end you will have the last laugh when and if they find your medicine, because they would have gone through all the trouble for nothing! Also keep your original rec with you but hidden, make a copy of it and if needed give that to them. I know first hand that some of those fuckers will actually take the original rec and make it "disappear". But if they make a copy disappear, then you can retain the original for court. You could also just get your doctor to issue you another one. Bottom line, I drive around hoping to be pulled over, just so I can piss them off. It's actually kind of fun, and so far to date, my record is spotless, and I have been pulled over a handful of times with no negative outcomes.
