It appears that Uruguay has beaten Nicaragua to the punch. In today's AP news on Yahoo, "Uruguay is drawing up plans to sell government-grown marijuana. ... President Jose "Pepe" Mujica ... openly declar(ed) that the drug war has failed. Smoking pot — if not growing and selling it — is already legal in Uruguay, and supplying the weed is a $30 million business, the government said."
Of course, little, poor Nicaragua lay in the shadow of the super-meanie waging the drug war (while US Big Pharma & local governments pump kids full of amphetamines - Ritalin & Adderall.) But, should Nicaraguan ever truly feel they're got a sovereign right to act independently, for their own benefit . . . (Fuggetaboutit - just look at the results of the US drug war in Honduras.)
Still just imagine a regular flow of aging/ailing hippies driving down the PanAm for those final puffs in tropical sunshine. And all that revenue pumped into Nicaraguan coffers! (Only aging/ailing rock stars & moguls can afford to fly to Uruguay.)
