I would humbly suggest that we are missing the point of marijuana prohibition in this thread. Just follow the money. Who profits from prohibition? Let's just call them the Drug War profiteers. This would be local police departments who get federal grants for drug enforcement efforts, and who can fund their department through [unconstitutional] confiscated property from drug busts. These profiteers would also include government functionaries whose careers depend upon prohibition, such as the DEA,ONDP, FBI and their para-military units that track down MJ users,sellers, growers, even critically-ill users. Then of course their are the politicians who have made a grandstanding career out of the Drug War, too many to mention here. Finally, there is international organized crime that would stand to lose considerably if MJ where suddenly allowed to be grown and sold legally. So put the profiteers together: police, federal government, organized crime. What a happy troika!

Put simply, not a f**king chance in hell that MJ will be legal in my lifetime.
