The US Federal Government has long been accused of doing far more to assist the global drug trade than fight against it. They were caught assisting the Sinaloa drug cartel, they helped save Afghanistan's opium production, and the DEA may be little more than a spy agency in disguise. Well now there's even more hard evidence from Bolivia:

Drug dealing now represents less than 1% of the Andean country's GDP, in a sustained reduction ever since the expulsion of the United States DEA agency.

According to data from the United Nations, Bolivia achieved a reduction in the amount of coca fields — the plant which is used as a raw material for the elaboration of cocaine — approximately in an 11% since the year 2014, and in over a 30% since 2010, which amounts to four consecutive years of decline, from over 30 thousand to some 20 thousand hectares.
