I had a thought the other day. Cannabis is part of the Cannabaceae family along with Humulus (hops) which is a key ingredient in lager type beer. Considering the two are close in their genetic makeup could you cross breed the two and make a plant that has properties of cannabis and also hops so you could use it in beer? I'm not a botanist but this seems like its plausible. I was at the grocery store a while back and they were selling a cross between a apple and a grape they called it a "Graple".
