(NORML) A rise in the self-reported consumption of cannabis during the years 2006 to 2010 corresponds with a significant decline in Americans’ use of cocaine and methamphetamine during this same time period, according to a new RAND study commissioned by the White House Office of National Drug Control Policy (ONDCP).
Researchers estimate that Americans increased their consumption of cannabis by approximately 30 percent during the years 2006 to 2010. During this same time, authors estimated that the public’s use of cocaine and methamphetamine declined, with Americans’ use of cocaine falling by half.
Americans’ consumption of heroin remained largely stable throughout the decade, the study reported. According to statistics compiled by the US Substance Abuse And Mental Health Services Administration, an estimated 4.5 million Americans have tried heroin in their lifetimes. By comparison, an estimated 12 million Americans have tried methamphetamine, 37.5 million have tried cocaine, and 111 million have consumed cannabis.
