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.

That alcohol causes cancer isn’t really news, but how it does so hasn’t been fully understood. A new study, published in the journal Alcoholism: Clinical and Experimental Research, adds an important new piece of information. Alcohol, it turns out, stimulates a type of cell transformation that turns cancer cells more aggressive and thus more likely to spread throughout the body.

As we’ve noted before, research shows that cannabinoids (marijuana’s unique, active components) interfere with tumor growth and may actually prevent cancer.

At a Las Vegas news conference today, the Marijuana Policy Project of Nevada announced details of a $10,000 challenge to the people of Nevada. MPP-NV will pay $10,000 to anyone who can disprove three statements of fact that demonstrate that marijuana is objectively and unquestionably safer than alcohol.

The challenge, announced by MPP-NV manager Dave Schwartz with a large mock check for $10,000,  kicks off a long-term public education campaign regarding the relative harms of marijuana and alcohol, and the harm caused by marijuana prohibition. [Read more →]

A study just published online by the journal Neurotoxicology and Teratology suggests that marijuana may protect the brain from some of the damage caused by binge drinking.

The study, by researchers at the University of California San Diego, used a type of high-tech scan called diffusion tensor imaging to compare microscopic changes in brain white matter. The subjects were students aged 16-to-19, divided into three groups: binge drinkers (defined as having five or more drinks at one sitting for boys or four or more for girls), binge drinkers who also smoked marijuana, and a control group who had very little or no experience with either alcohol or drugs.

As expected, the binge-drinking-only group showed evidence of white matter damage in eight regions examined, as demonstrated by lower fractional anisotropy (FA) scores. But in a finding the researchers described as “unexpected,” the binge-drinking/marijuana group had lower FA scores than the controls in only three of the eight regions, and in seven regions the binge-drinking/marijuana group had higher scores – indicating less damage – than the binge drinkers who didn’t use marijuana (unfortunately, not all of these stats are in the summary linked above; access to the full article requires payment).

MPP’s director of state campaigns, Steve Fox, is the co-author of a new book entitled, Marijuana is Safer: So why are we driving people to drink? The purpose of this book is to educate Americans about the relative harms of marijuana and alcohol, and to force them to consider why we punish adults who use the less harmful substance.  The critically acclaimed book also provides supporters of marijuana policy reform with the information and talking points necessary to spread the “marijuana is safer” message to friends and family.

To raise awareness about the book, the authors are coordinating a “Book Bomb” that will take place tomorrow, August 20.  The goal is to have hundreds of people order the book from Amazon.com on the same day so that it reaches #1 on the online bookseller’s rankings.  As far as we know, no book advocating for marijuana policy reform has reached that milestone.  To learn more about the book and to sign up for the Book Bomb, visit http://www.marijuanabookbomb.com If you sign up, you will get an email tomorrow reminding you about the Bomb.

Thanks in advance for participating!  And please share this blog post with any friends who might be interested.

British scientists warn increasing hostility toward scientific evidence that contradicts political agendas could hinder the collaborative relationship policy and science enjoys in Britain, the Guardian reported yesterday.

Last November, the British government ignored the advice of its Scientific Advisory Board and moved marijuana into a more dangerous class of drugs, a move described by top scientists at the time as “a sad departure from the welcome trend … of public policy following expert scientific advice.”

Of course, here in the United States, government has been ignoring its scientific advisors on marijuana policy for decades, at least since Nixon first lined his bird cage with the two-year study he commissioned recommending marijuana’s decriminalization.

And that unwelcome trend continues to this very day here, as evidenced by drug czar Gil Kerlikowske’s recent lie that marijuana “has no medicinal benefit.” Not sure who Kerlikowske’s scientific advisors are, but the one we taxpayers use, the National Academy of Sciences’ Institute of Medicine, says: “Nausea, appetite loss, pain, and anxiety … all can be mitigated by marijuana.”

Then again, it doesn’t take a scientist to know that it’s wrong to deny sick people medicine that eases their pain, or to arrest responsible adults because they prefer a drug that’s safer than alcohol or tobacco.

That would seem to be the implication of a new study just published online by the journal Drug and Alcohol Dependence. But the study’s authors aren’t so sure.

The study measured drinking patterns in individuals who enrolled in treatment for marijuana dependence as part of a study designed to test different treatment methods. Participants greatly reduced their marijuana use, but 73 % also increased the number of days on which they drank alcohol by at least 10%. Most also increased the amount they drank on those drinking days. This seems like prima facie evidence of a substitution effect — alcohol being substituted for marijuana.

The researchers, surprisingly, don’t draw that conclusion, based on the fact that drinking behavior did not seem to change in proportion with marijuana use. Instead, they write, “We are left with a mystery.”

It seems to me that, in the absence of another plausible cause, substitution of booze for marijuana still looks like the most likely explanation, though more research is absolutely needed. Given what’s known about the much more serious health risks of alcohol as compared to marijuana, this ought to cause at least some unease regarding the 140,000-plus Americans forced into treatment for alleged marijuana problems by the criminal justice system each year.

An argument regularly raised by those who want to keep marijuana illegal is that because there is no equivalent of a breathalyzer test for marijuana intoxication, DUI laws would be impossible to enforce. The California Supreme Court just shot a very large hole in that argument.

It’s an odd argument anyway, given that tens of millions of Americans regularly take drugs that can impair driving — pain relievers, antihistamines, etc. — for which there is no simple, roadside test. For most of these drugs, and for marijuana, the old-fashioned field sobriety test works quite well.

Still, people have tended to regard the alcohol breath test as the gold standard. Now, the California Supreme Court has ruled unanimously that defendants can challenge the accuracy of these tests. As the Los Angeles Times reported, “Even though experts say the standard ratio used to derive a blood-alcohol concentration from breath generally approximates or even underestimates the amount of alcohol the driver consumed, they also agree that Breathalyzer results may sometimes overestimate the amount of alcohol in the blood.”

No one — repeat, no one — should ever drive while impaired by anything. But it’s time to put aside the false notion that Breathalyzer tests are infallible, or that there’s no way to enforce laws against driving under the influence of marijuana.
