It'd be a lot easier to make cheap, pure heroin available to people who choose to use it. Switzerland does just that and it seems to benefit their society while taking money out of the pockets of the drug cartels: http://drugwarfacts.org/region/switzerland

Physically easier yes, politically easier debatable.

Politically easier than destroying the cash crops of a foreign country? Seems unlikely. :-)

Proof is in the pudding. People generally come around.
