Of course people are still being convicted of weed and firearm, but it gets recorded as gun law violation and nobody cares, cuz left hates guns and right hates weed, so they'll never repeal it.
So imagine you're in a car, get pulled over, it smells of weed so the cop executes a search, and he finds a pipe in the glove compartment. You're getting arrested for PDP there 100%. Even if it genuinely wasn't yours, you stand very little chance of acquittal. Beyond a reasonable doubt doesn't mean 'is there some other viable explanation' because there literally always is. It means is it reasonably likely that one of these other explanations is what really happened.
