Do Latin Americans Do a Lot of Drugs?

I was doing research on Asia and found that even though the region produces a large amount of illegal drugs, people in the producing countries statistically dont do drugs and these countries have no drug culture. Is the same true for Latin America. A huge chunk of the world's cocain comes from Columbia, but are Columbians themselves known to be consumers of drugs on a large scale. What about the rest of the region? Thanks
