Former President Bill Clinton says in a new documentary that his administration’s attempts to limit drug trafficking from Colombia "hasn’t worked." Politico reports. Clinton joined other world leaders, including former President Jimmy Carter,in filmmaker Sam Branson’s "Breaking the Taboo," which charges that the global war on drugs is a failure.

"What I tried to do was to focus on every aspect of the problem. I tried to empower the Colombians for example to do more militarily and police-wise because I thought that they had to. Thirty percent of their country was in the hands of the narcotraffickers," Clinton says in the film, which is available free online. He says, "Well obviously, if the expected results was that we would eliminate serious drug use in America and eliminate the narcotrafficking networks — it hasn’t worked."
