> Where will they get the cannabis from? they don't have enough lands, import from the US/Canada i bet? ;)

"they don't have enough lands"? Are you sure about that? Given that less than 10% of Germans consume cannabis on a regular basis, I don't think you'd need all that much land to supply them all with generous amounts of weed. Also, since weed is going to be quite a profitable crop, I'm pretty sure some farmers will be eager to cease their corn/wheat/whatever production for it.
