According to a new White House-commissioned report, the number of chronic marijuana users increased by 84.3 percent between 2000 and 2010.
Defined as those who using the drug on four or more days in the past month, the report, conducted by the RAND corporation, found a sharp spike in chronic pot use in the 10-year period, according to Cybercast News Service.
“In January 2012, the U.S. White House Office of National Drug Control Policy (ONDCP) asked RAND to generate national estimates of the total number of users, total expenditures, and total consumption for four illicit drugs from 2000 to 2010: cocaine (including crack), heroin, marijuana, and methamphetamine (or meth),” the report explains.
Called What America’s Users Spend on Illicit Drugs: 2000-2010, the report states that chronic marijuana users climbed from 7,000,000 in 2000 and to a high of 12,900,000 in 2010.
The numbers indicate a number of dips and spikes in marijuana use during that decade, but a general upward trend and a steady rise from 2007-2010. RAND also found an increase in users who do the drug weekly, more than weekly, or daily.
The report asked respondents a new question about “blunt use,” finding that some people don’t put “blunt” and “marijuana” use in the same category.
“The counts of marijuana users (and, later, marijuana-use days) include not only those who indicate directly that they have used marijuana, but also a modest number who deny using ‘marijuana’ when asked about it in the standard battery of questions but who nonetheless do indicate later in the survey that they have used blunts, a particular form of marijuana use,” says the report.
And in a measure of the amount of pot used and the money spent on it, the report concluded that 4,734 metric tons of pot were used in 2010, totaling $40.8—up from 3,024 metric tons and $21.6 billion in 2000.
