Better yet, stop the drug war and give freedom to people who wish to screw up their lives with drugs. Taking the crime out of drugs, thereby reducing the scarcity factor in their cost, would reduce overall crime committed by addicts.
As quid pro quo, eliminate all government financial support for rehab, welfare for addicts and such. Society wins by placing accountability for drug problems on the individuals who choose to use them self-destructively. Poppy production would devolve to the most efficient, and the flow of drug money to terrorists would ebb.
