I live in cali and have my card. Knock on wood, I have been pulled over multiple times by cops for other reasons like speeding or tinted windows and they smelled the weed with no legal action taken upon me. Cops have asked me where the weed is at and I pull out the meds and my card from my center console. They look at it smell it and give it back everytime. I hand a caregiver the first year I got my card. Cops saw the plants my friend was growing for me with my script hanging, they just took pictures and left. We harvested a few weeks later, never heard from the cops again. Hell I have even smoked weed in the parking lot of a bar in my car and the cop just said stop. Cop pulled me over multiple times, never got arrested, meds never confiscated. Just be honest and dont be a dick and cops be coo to you.
