Marijuana Use By The Numbers

FYI: Feel free to also comment on this commentary (and digg it) at the Huffington Post here and at Alternet.org here.

The U.S. Department of Health and Human Services has once again released their annual survey on “drug use and health” — you know, the one where representatives of the federal government go door-to-door and ask Americans if they are presently breaking state and federal law by using illicit drugs. The same survey where respondents have historically under reported their usage of alcohol and tobacco — these two legal substances — by as much as 30 to 50 percent, and arguably under report their use of illicit substances by an even greater margin. The same survey that — despite these inherent limitations — “is the primary source of statistical information on the use of illegal drugs by the U.S. population.” Yeah, that one.

So what does the government’s latest round of ‘statistical (though highly questionable) information’ tell us? Nothing we didn’t already know.

Despite 70+ years of criminal prohibition, marijuana still remains widely popular among Americans, with over 102 million Americans (41 percent of the U.S. population) having used it during their lifetimes, 26 million (10 percent) having used it in the past year, and over 15 million (6 percent) admitting that they use it regularly. (By contrast, fewer than 15 percent of adults have ever tried cocaine, the second most ‘popular’ illicit drug, and fewer than 2 percent have ever tried heroin — so much for that supposed ‘gateway effect.’) Predictably, all of the 2008 marijuana use figures are higher than those that were reported for the previous year — great work John Walters!

Equally predictably, the government’s long-standing prohibition and anti-pot ‘scare’ campaigns have done little, if anything, to dissuade young people from trying it. According to the survey, 15 percent of those age 14 to 15 have tried pot (including 12 percent in the past year), as have 31 percent of those age 16 to 17 (a quarter of which have done so in the past year) — percentages that make marijuana virtually as popular as alcohol among these age groups. By age 20, 45 percent of adolescents have tried pot, and nearly a third of those age 18 to 20 have done so in the past year. And by age 25, 54 percent of the population has admittedly used marijuana.

Question: Does anyone still believe that marijuana prohibition is working — or that all of these people deserve to be behind bars? (more…)

Who Are You? US Government Statistics on Adult Marijuana Users

[UPDATE: The portion of my post relating to race and ethnicity data was missing one of the pie charts.  The text has been changed to reflect the correct data from the missing chart.  My apologies for any confusion. -- Russ Belville]

The US Government’s Substance Abuse and Mental Health Data Archive (SAMHDA) is a treasure trove of information from the National Surveys on Drug Use & Health 2001-2007. I’ve always been uncomfortable discussing most marijuana statistics from this and other reports because the data so often cover marijuana use from age 12 and older. NORML stands for the responsible adult use of marijuana, so I wanted to know the facts on age 18 and older (some may wish for numbers age 21 and older; I only picked 18+ because the first data column is age 18-25).

The essential caveat: these are the people who will tell these things to a stranger for a government survey.

First of all, how many adults in the United States have ever smoked weed? The Survey breaks down the data by age categories and gives the percentage of the sample (Unweighted N) that answered yes or no to the question. Then they extrapolate, based on US adult population demographics, how many people in the United States (Weighted N) would answer yes or no.

US Adults Who Have Ever Used Marijuana by Age

That’s 95 million folks who’ve smoked herb.  The percentage is how many within that age group have used – a majority of 18-25s and 35-49s and real close on the 26-34s.  Or look at it this way: If you see someone under age fifty, flip a coin. Heads, they’ve smoked pot, tails, they haven’t.

When you look at the population of adults who have ever used marijuana, we find that young people (18-34) and middle-aged people (35-50) are equally represented at 36% of the population.

More fun with government numbers and Excel 2007 after the break…
