U.S. policy on drug trafficking is not consistent with the need to put an end and actively repress the consumption of drugs. The solution is not based on the destruction of a native plant, coca, in the continent, but on an active fight against the Colombian drug mafia, which has created a great money and crime empire in Colombia with powerful ramifications outside its borders.
There is no need to repress the consumption of drugs, and there is no crime in Colombia.
