I have a friend who suffers from glaucoma, and he says that medical marijuana is one of the few drugs that really reduce the pressure in his eyes. He really does have a prescription for the stuff, and he lives close to several medical marijuana dispensary locations. I went with him one time to do some comparison shopping before filling the prescription.
Some of these dispensaries really did remind me of traditional drugstores. They had other items on the shelves, and the pharmacists wore white coats. They were the kinds of places where you turned in your prescription and came back when it was filled and bagged up. I think the previous poster (AnswerMan) would have been impressed, but I thought it was a little too sterile.
The other dispensaries were a lot looser. They had other supplies and devices for smoking marijuana, like wrapping papers and bongs. One medical marijuana dispensary had a menu board, and it was just like ordering a meal from a fast food restaurant. My friend ended up buying his pot at one of those places, since he needed something stronger than the standard government-approved marijuana.
