Wise up? Really? I'm wise enough to know that a greedy middle man is not needed. If the dispensary is on the up and up...then thats a different story. But I'll bet donuts to dollars 80% or more are crooks taking advantage of a system ripe for then taking.
...and what's your solution? Many people enjoy the dispensary model. You can't take advantage in a open market - dispensaries offer a variety of strains to help people find the meds that work best for them. Also, I don't understand any problem - worst case scenario someone buys weed for recreation, which would happend regardless of med-MJ except in a legal market the city and state sees taxes to help a devastated economy.
