The Center for Medicinal Cannabis Research (CMCR), based at the University of California, San Diego, published a report today summarizing the results of clinical trials studying medical marijuana’s efficacy in treating pain. The studies, funded by CMCR under the mandate of a 1999 legislative action, found that marijuana is particularly helpful in relieving pain associated with nerve damage and in treating the muscle spasticity from multiple sclerosis.

The summary CMCR presented to the California legislature today brings together data from 15 clinical studies – six of which have been published in respected medical journals.

In 2002, then-drug czar and rabid medical marijuana opponent, John Walters said, “The Center for Medicinal Cannabis Research is currently conducting scientific studies to determine the efficacy of marijuana in treating various ailments. Until that research is concluded, however, most of what the public hears from marijuana activists is little more than a compilation of anecdotes.”

Well, the proof is in. Now it’s time for Congress to bring federal medical marijuana policy into line with the science.

I posted the story a couple weeks ago about a medical marijuana lab in Denver being raided by the DEA, but it turns out the lab inadvertently led agents to their doors.

According to Betty Aldworth, the lab’s director of outreach, employees were caught off guard by the Drug Enforcement Administration’s visit because they did everything they could to be in compliance with DEA requirements, even formally applying for an analytical lab license.

“We didn’t need to do that, but we thought it was the right thing to do,” Aldworth told the Denver Westword. But as it turns out, doing the right thing isn’t always the best solution, at least not with the DEA. Since the lab did in fact apply for a license through the DEA, the law requires the DEA to follow up on the suitability of applicants for permits, including investigating whether the applicant is in violation of any federal laws.

So, technically the lab was not raided. But should it really be a priority of the DEA to investigate an organization whose sole purpose is to test the potency of a legitimate medicine to help legitimate patients?

Yet another myth about marijuana takes a beating thanks to some splendid research out of Scandinavia. Although it’s no surprise to MPP’s fans, marijuana use has no link to suicide. A thorough study of Swedish military men confirms that those who use marijuana are no more likely to take their own lives than those who don’t. Prohibitionists often grab results like these and squeal “the sample is too small to mean much,” but this research focused on more than 50,000 people. If you can’t get marijuana to link to suicide in 50,000 people, you can’t get marijuana to link to suicide.

Prohibitionists also often shout “Well, you didn’t follow them up long enough. They would have killed themselves eventually.” This study followed the participants for 33 years. If you can’t link marijuana to suicide after 33 years, you can’t link marijuana to suicide.  If there’s no smoke, there’s no fire. This study also showed markedly smaller links between marijuana and depression than folks thought.

Clearly, the biggest bummer about marijuana doesn’t stem from its use; it’s from arrests. At 800,000 per year, our current rate,  we’d have 26,400,000 more arrests for the next 33-year follow-up. Let’s not let that happen. It’s just too depressing.

Dr. Mitch Earleywine is Professor of Clinical Psychology at the University at Albany, State University of New York, where he teaches drugs and human behavior, substance abuse treatment and clinical research methods. He is the author of more than 100 publications on drug use and abuse, including “Understanding Marijuana” and “The Parents’ Guide to Marijuana.” He is the only person to publish with both Oxford University and High Times.

Back in October, the British government fired its chief drug adviser, Prof. David Nutt, for saying that marijuana is less dangerous than many legal drugs and that British laws should be changed to reflect this reality. Many other members of the United Kingdom’s Advisory Council on the Misuse of Drugs resigned in protest

Then this week, Les Iversen, a former pharmacology professor at the University of Oxford, was announced as Nutt’s interim replacement as the council’s chairman. And guess what? He’s also said that the UK’s marijuana laws should change.

The federal government just released the latest ‘Monitoring the Future’ survey of teen drug use, and the results do not bode well for current policies. More high school seniors report smoking marijuana in the past 30 days than smoked cigarettes: 20.6 percent vs. 20.1 percent. And marijuana use is up (albeit in the same general range it’s been in for several years) while teen cigarette smoking continues to decline, and has dropped markedly since the early ‘90s.

Regulation of tobacco, combined with solid educational campaigns, has clearly cut youth access to cigarettes. It’s time for officials to take off their blinders and apply those same proven policies to marijuana.

Oh, and just in case someone tries to blame medical marijuana laws for the rise in teen marijuana use, use by teens has actually gone down in the medical marijuana states.

The Journal of Neuroscience just published a new study that is particularly interesting in light of recent reports that marijuana may effectively substitute for abuse of more dangerous drugs.

In the new study, rats were taught to self-administer heroin and conditioned to associate that behavior with a light that flashed on above the lever that dispensed the heroin. At various stages in the procedure, some of the rats were treated with cannabidiol (CBD), a cannabinoid that doesn’t make you high, but which has a number of really interesting properties.

David Nutt, removed as chair of the British government’s Advisory Council on the Misuse of Drugs for daring to speak the unwanted truth that marijuana is safer than alcohol, is speaking out again, this time in the pages of The Lancet, one of the world’s top medical journals. Unfortunately, you can read only the first few lines of Nutt’s column unless you pay for full access (correction: you have to register but don’t have to pay — thanks to Just Legalize It for pointing this out), but he makes a critical point that many politicians surely won’t like: “The control of cannabis use through regulation rather than criminalisation has proved safe and effective in the Netherlands, and was indeed suggested in The Lancet as far back as 1963.”

Maybe someday governments will base policy on facts and data. It sure would be nice.

For some time we’ve been pointing out the massive pile of evidence that THC and other cannabinoids have potential as anticancer drugs. A new study out of Thailand demonstrates that THC can fight cholangiocarcinoma – cancer of the bile duct. This is a rare but deadly form of cancer, with only 30 percent of patients still alive after five years, according to the  Cholangiocarcinoma Foundation. Based on these new lab results, the Thai researchers conclude, “THC is potentially used to retard cholangiocarcinoma cell growth and metastasis.”
