A new report finds that the use of cocaine dropped sharply across the United States from 2006 to 2010, but the amount of marijuana smoked increased significantly.
Researchers discovered that the amount of pot consumed by Americans increased by more than 30 percent from 2006 to 2010, while cocaine consumption fell by about half.
Meanwhile, the use of heroin use was fairly stable from 2000 to 2010. The findings come from a report compiled for the White House Office of National Drug Control Policy by researchers affiliated with the RAND Drug Policy Research Center.
They say their analysis shows that Americans likely spent more than one trillion dollars on cocaine, heroin, marijuana and methamphetamine between 2000 and 2010,
Researchers say the report does not address the recent reported spike in heroin use or the consequences of marijuana being legalized in Colorado and Washington.
