My  recent post about medical marijuana and  young patients got picked up by the folks over at OpposingViews.com. And that prompted writer Katherine Ellison, whose New York Times story I’d taken issue with to post the following response:

a couple corrections for you

Hi, Bruce –

For the record, my byline is Katherine, not Kathy. And I guess I can understand your frustration at not having a story that reflects your advocate’s view of marijuana as a safe , cure-all drug, appropriate for all ages. However, I stand by my reporting, which I think was a responsible effort to bring awareness to an increasing problem of irresponsible doctors given way too much leeway with an untested drug on adolescents.

Oh dear. I generally don’t like to get into fights with reporters, but I’m grateful that Opposing Views allowed me to post the following response:

First, Katherine, I apologize for using your name as you signed it on your emails to me rather than as published in your byline. Nevertheless, I find it frustrating that you appear to be deliberately misinterpreting both what I’ve written here and what I said on the phone during our lengthy conversation.

You know full well that I don’t consider marijuana a cure-all and that I do not expect you to endorse my opinions in print. I do expect you, in reporting a scientific issue, to actually address the relevant science in a way that will enlighten readers.

Your story failed to explain meaningful scientific evidence provided to you by both me and Paul Armentano suggesting a positive effect of marijuana on ADHD as well as the biochemical basis for such an effect being plausible. You included a scientifically nonsensical quote from Stephen Hinshaw calling marijuana for ADHD “one of the worst ideas of all time” because marijuana disrupts attention and memory in normal people. But we know that the brains of ADHD patients don’t work like those of normal people — which is why stimulants like Ritalin have a calming effect, the exact opposite of their effect on most of us. Did you even bother to ask Hinshaw this obvious followup question?

You also included a cavalier quote from Edward M. Hallowell claiming that marijuana use “can lead to a syndrome in which all the person wants to do all day is get stoned, and they do nothing else” — without bothering to note that this so-called “amotivational syndrome” has been debunked again and again. One example that I sent you, and which you apparently ignored, was the 1999 Institute of Medicine report commissioned by the White House, which states on pages 107-108, “When heavy marijuana use accompanies these symptoms, the drug is often cited as the cause, but no convincing data demonstrate a causal relationship between marijuana smoking and these behavioral characteristics.” Many other expert reviews have come to the same conclusion.

I am not asking you to agree with me or to tout marijuana as a cure-all, which it manifestly is not. As a longtime health journalist myself, all I am asking is for you to do your homework as a reporter.

Lately there has been a small burst of media fascination with what by most accounts is a rare occurrence: Use of medical marijuana recommended by a physician by patients under 18. Any psychoactive drug, including marijuana, should be used with caution in children, but there is no reason that these infrequent cases should be shocking. Indeed, they should be taken as signposts on the road to urgently-needed research. [Read more →]

In case anyone needs proof of the mass media’s tendency to repeat government pronouncements without bothering to check their accuracy, here’s a small but telling example:

Inexplicably, when the U.S. Department of Justice issued a memo last month explaining that it would generally refrain from prosecuting medical marijuana activities that are clearly legal under state law, it mistakenly indicated that there are 14 medical marijuana states. DOJ’s goof was to include Maryland, where medical marijuana is not actually legal, but where state law provides for reduced penalties to patients who successfully present a medical-necessity defense.

DOJ’s goof has now traveled though most of the known universe, repeated by credulous news media. The Associated Press, after talking to MPP, at least included an explanatory note about the discrepancy, but others just repeated the mistake with no explanation, including Katie Couric of CBS, the  Washington Post, Voice of America, the Guardian of London, and even the editorial page of the New York Times.

C’mon, guys, tell me that fact-checking isn’t entirely dead. Kudos to those media outlets that got it right, including CNN.

Before Michael Pollan’s best-selling books about food and the food industry, he wrote a fascinating volume about humanity’s symbiotic relationship with plants, called “The Botany of Desire.” That book is now a PBS special, airing for the first time this week, on October 28 at 8 p.m. If you have friends, family, coworkers, etc., who’ve never thought about our relationship with marijuana beyond the latest hysterical news story, this is the show they need to see.

About the same time as I was posting about the Washington Post’s refusal to run  MPP’s response to Charles Lane’s preposterous anti-medical-marijuana diatribe, the Post allowed Lane to strike again, with yet another online column filled with distortions and misstatements. I’m old enough to remember when the Post was a great newspaper. Yesterday I was angry; now I’m just sad.

On Oct. 20, the Washington Post published an inaccurate and arguably libelous anti-medical marijuana diatribe by Charles Lane on its Web site. After a deluge of complaints, the version now posted is cleaned up slightly: shorn of an offensive reference to Supreme Court medical marijuana plaintiff Angel Raich as a hypochondriac and with a feeble “clarification” appended. But it’s still a cascade of distortions and inaccuracies. Since the Post declined to print MPP’s reply, we thought we’d share it with you:

Setting the Record Straight on Medical Marijuana
by
Bruce Mirken and Mike Meno

Charles Lane’s column, “Medical marijuana is an insult to our intelligence,” (Oct. 20) was riddled with inaccuracies. Had Mr. Lane bothered to review the medical literature, he would have found not “hokum” and “snake oil,” as he calls it, but a small mountain of published, peer-reviewed research documenting that medical marijuana is a safe, effective, and sometimes even life-saving medication for many seriously ill Americans.

Just two days after the prestigious Columbia Journalism Review proclaimed that the mainstream media are “are acting less childish about pot,” along comes the New York Daily News to prove that childishness is alive and well.

On Wednesday, MPP began airing two new TV ads around New York state in support of medical marijuana legislation. The spots feature real patients talking about the severe pain they suffer every day and how medical marijuana helps them. Amazingly, these serious and sober ads were rejected by three New York City TV stations.

The Daily News found it all quite amusing: “Just say yes! That’s the message a national pro-pot group is taking to New York’s airwaves,” the paper wrote. After quoting me about why we did the campaign, the story concluded, “The city’s ABC, CBS and Fox affiliates harshed the group’s buzz by declining to run the ads, Mirken added.”

Uh, no, I actually didn’t say anything remotely like that. But what I really said wasn’t nearly as cute.

At least some in the international news media have belatedly discovered a study casting doubt on the purported link between marijuana use and schizophrenia. I say “belatedly” because the study was published online back in June, although the print version came out this month.

A group of British researchers examined a rather basic notion: If marijuana use  causes schizophrenia, then a major increase in marijuana use should lead to an increase in schizophrenia diagnoses in the following years. In an enormous sample of some 600,000 Britons, no such thing occurred – indeed, a spike in marijuana use beginning in the mid-1970s was followed by rates of schizophrenia that either remained stable or declined.

Of course this is not the first time that a lack of connection between marijuana use rates and schizophrenia incidence has been noted in the scientific literature. For example, a 2006 review in the Canadian Journal of Psychiatry noted that “the treated incidence of schizophrenia did not obviously increase during the 1970s and 1980s when there were substantial increases in cannabis use among young adults in Australia and North America.” (Alas, that rather important discussion isn’t mentioned in the summary linked above, which is all you can get for free).

Overall, the evidence strongly suggests that marijuana may worsen or trigger schizophrenia in a few individuals with a pre-existing vulnerability, but that it is not a significant cause of mental illness in healthy people. That rather nuanced reality tends to be a bit too complicated for many in the media.
