It must have been a slow news day.

According to Google News, more than 750 media outlets — that’s 7-5-0, folks — have now weighed in on this week’s pot scare story du jour: “Smoking marijuana causes testicular cancer.”

So is there any truth behind the provocative headline? Some, but hardly enough to justify the media’s feeding frenzy.

Researchers at the Fred Hutchinson Cancer Research in Seattle matched 369 men with of testicular germ cell tumors (TGCTs) with 979 healthy controls. Here’s what they found.

Men who self-reported having “ever used” marijuana had no statistically significant risk of testicular cancer compared to healthy controls who never used pot.

Men who reported currently using marijuana at least once per week, and who had started smoking pot prior to age 18, had an elevated risk compared to controls of contracting a type of testicular cancer known as nonseminoma.

Sounds scary, huh?  Well here’s the catch.

According to the federal government, millions of people smoke marijuana regularly. By contrast, diagnoses of nonseminoma, which typically affects males between the ages of 15 and 34, are extremely rare.

How rare?

Nonseminomas account for fewer than one half of one percent of all cancers among American men.

Further undermining the study’s hypothesis is this: Since the 1970s, the percentage of American males smoking pot has climbed dramatically. By contrast, incidences of nonseminoma have risen only nominally during this same time period.

Of course, this is hardly the first time the mainstream media has jumped ugly on cannabis. Around this same time last year, news outlets from Reuters to Fox News declared that marijuana posed a greater cancer risk than cigarettes. Only problem was that the study they were reporting on actually demonstrated the opposite.

So why does the mainstream media continue to get the story wrong when it comes to pot? Good question. You can read my abbreviated answer here. And while you’re on NORML’s site, get the skinny on what the scientific literature really has to say about any potential links between marijuana and cancer here, here, and here.

For over a decade now I’ve been telling folks that compounds in cannabis can selectively target and kill malignant cancer cells. It seems like some media outlets finally starting to get the message.

Today, the good folks at HuffingtonPost.com published my latest essay on the subject, “What Your Government Knows About Cannabis And Cancer — And Isn’t Telling You.”

Since the Huffington Post is an online medium, I made it a point to include nearly a dozen links to pertinent research and clinical/pre-clinical trials demonstrating that cannabinoids possess anti-cancer properties.

Fortunately, in the past 10 years scientists overseas have generously picked up where U.S. researchers so abruptly left off, reporting that cannabinoids can halt the spread of numerous cancer cells — including prostate cancer, breast cancer, lung cancer, pancreatic cancer, and brain cancer. (An excellent paper summarizing much of this research, “Cannabinoids for Cancer Treatment: Progress and Promise,” appears in the January 2008 edition of the journal Cancer Research.) A 2006 patient trial published in the British Journal of Cancer even reported that the intracranial administration of THC was associated with reduced tumor cell proliferation in humans with advanced glioblastoma.

For most visitors to the Huffington Post, my essay will be their first exposure to this information, but ideally, not their last. Hopefully, readers of the site — which is one of the most visited on the Internet — will join us in our calls to end the US government’s multi-decade long denial of this potentially groundbreaking research.

Please feel free to leave a comment and/or circulate this article widely (Digg it, reddit, buzz up, etc.) My last Huff Post essay, “Don’t Buy The ‘Potent Pot’ Hype,” received nearly 100 comments, a personal response from the Drug Czar’s office, and earned me a guest spot on Dr. Drew Pinsky’s live nationally syndicated radio show. That said, in my opinion, the government’s cover-up of pot’s anti-cancer abilities is a far more important topic; hopefully we can get a similar buzz started.

PS: Those interested in learning more about this topic can download an audio file of my recent guest appearance on the radio show, “Sex, Drugs, and Civil Liberties,” (KOPN: Columbia, Missouri) here.

Take a closer look at how the mainstream media lies about cannabis.

Full Story

Smoking pot, even long-term, is not associated with an increased risk of developing cancers of the head and neck, according to the results of a just-published case-control study from New Zealand.  

“This population-based study did not find a statistically significant increase in the risk of head and neck cancer in adults [under age 55] from cannabis,” authors concluded. “[Even] the risk associated with the highest tertile of cannabis use (defined as one joint per day for more than eight years) was not statistically significant after adjustment for cofounding variables including tobacco smoking, alcohol consumption, and level of income.”

So for the second month in a row we have researchers from New Zealand telling us that pot smoking has little-to-no association with cancer. But perhaps you missed the first study. That would be understandable because the mainstream media deliberately obscured its findings with alarmist headlines like “Cannabis Bigger Cancer Risk Than Cigarettes” and “Experts Warn of Cannabis Cancer ‘Epidemic’” — headlines that, in fact, were nearly the opposite of what the study actually said.

International media headlines reporting that heavy marijuana smokers have a six-fold risk of coming down with lung cancer are, predictably, a whole lot of hot air.
