I could give a fuck if people misuse the medical marijuana system to get high and i'm far from a pothead. If that's their measure to get their weed without fear of being criminal prosecuted, then so be it. You say "try harder to get it legalized", i'm pretty sure marijuana legalization and decriminalization is on ballots to be voted on all the time in California, so it's not like people aren't out there trying.
I know there are people who legitimately need it for medical issues such as aids and cancer, but why connect them to other people? Actually have some sort of evidence that other people are going to cause them to lose their medicine before bashing them instead of coming up with fake hypothetical situations that have never happened and won't happen as a basis to bash people, that's pretty stupid.
