Cocaine is currently one of the world’s worst and biggest problem drugs and much of it is coming from South America. And now some very game travelers to Sierra Nevada in Colombia are going on trips to see this evil drug being manufactured. For as little as $9 a guide takes them deep into the La Ciudad Perdida or Lost City on a trail to a cocaine lab. Here farmers show how the leaves are grown then mashed together with a deadly cocktail of petrol, acids and other nasty ingredients to make a paste which becomes the base of cocaine. Many of the farmers and manufactures remain poor with much of the profits of this drug going to drug lords and fund the country’s unrest where corrupt paramilitary soldiers, and guerrillas has claimed so many lives in recent decades with massacres and killings of many innocent people.
