I can pretty much guarantee you Medbox will not have a monopoly on Marijuana Vending machines. if there is real money to be made with these things you better believe someone BIG will come along and know exactly how to change the system enough so it can't be challenged. After all - vending machines have been around for centuries and fingerprinting Identification has also been around and used in many other situations. and drug dispensing machines have been around for awhile as well. He just put the two together with some software and managed to get a patent.
Too bad their pps and market cap are so out of control - maybe someone would actually buy them out. But not at these prices.
