it was meant in jest because the CIA directly participated in the drug trade as uncovered by investigative journalist Gary Webb (who died from two gunshot wounds to the head...).
"Michael Cuesta’s movie 'Kill the Messenger' tells the story of Gary Webb, whose August 1996 investigative series “Dark Alliance,” published in the San Jose Mercury News, uncovered ties between the Central Intelligence Agency and massive drug peddling by the right-wing, mercenary Nicaraguan Contras. Webb’s three-part series established that in the 1980s the CIA-backed Contras smuggled cocaine into the US that was widely distributed as crack. The drug profits were then funneled by the CIA to the Contras in their war against the left-nationalist Sandinista government in Nicaragua.
