Big news: The American Medical Association adopted a new policy position today calling for the review of marijuana’s status as a Schedule I drug. The revised policy "urges that marijuana’s status as a federal Schedule I controlled substance be reviewed with the goal of facilitating the conduct of clinical research and development of cannabinoid-based medicines, and alternate delivery methods.” While it goes on to explain that the AMA is not stating support for state medical marijuana laws, the new…

There has long been reason to think that marijuana may be helpful to some patients with bipolar disorder, as certain cannabinoids have been shown in lab and animal studies to have effects that ought to be beneficial. Now, a new study from the University of Oslo finds that marijuana use is associated with better neurocognitive functioning in bipolar patients. In various tests of memory, learning, etc., bipolar patients who used marijuana did better than those who didn’t use it – the exact opposite…

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…

Last night’s election produced two noteworthy victories for the marijuana policy reform movement. In Maine, an estimated 58 percent of voters approved Question 5, making Maine the third state in the nation (along with Rhode Island and New Mexico) to establish state-licensed non-profit dispensaries that will provide medical marijuana to qualified patients. This is also significant because it is the first time such a system was enacted by voters. (The other two were approved by state legislatures.) And…

A frequent claim made by opponents of marijuana policy reform is that hardly anybody is ever really arrested for low-level marijuana offenses. But like most prohibitionist arguments, that's a lie. In California, where marijuana possession was “decriminalized” in 1976 and medical marijuana legalized 20 years later, the state Department of Justice reports that law enforcement conducted a record 78,492 marijuana arrests in 2008. About 80% of these (61,366) were for mere possession – not sale or cultivation. The…

Two members of Britain’s Advisory Council on the Misuse of Drugs have resigned in protest after the group’s chairman, Professor David Nutt, was fired last week for criticizing the UK government’s decision to strengthen penalties for marijuana offenses. Chemist Les King and pharmacist Marion Walker said that the government wrongly dismissed Nutt and violated his freedom of expression. Several other advisers on the once 31-member group are rumored to be “planning collective action” against British…

Last week, I posted the results of the MPP-commissioned poll showing that despite outrageous claims being made by local officials, there is wide support for medical marijuana among Los Angeles County voters. A new poll now shows that support for medical marijuana access isn't confined to Los Angeles. A poll released Wednesday in San Diego found super-majority support for medical marijuana in that city. The poll -- commissioned by addiction recovery Web site keepcomingback.com -- found 77% agreement…

Yesterday I posted a brief summary of a new study of vaporization of marijuana as an alternative to smoking. Since that original post, I’ve spoken to a couple of researchers about this study, and they raised a few points that seem worth sharing: First, for reasons that aren’t clear, before performing the tests of smoking and vaporization, the researchers put the marijuana through a drying procedure that ordinary marijuana consumers don’t do. This might have eliminated some plant compounds, such as…

Professor David Nutt, chairman of Great Britain’s advisory council on the misuse of drugs, was forced to resign today after he criticized the British government’s decision to toughen penalties for marijuana possession. Just a few hours prior to his sacking, Nutt had publicly condemned British politicians for “distorting” and “devaluing” scientific research used in the debate over illegal drugs. In an article published Thursday by the Centre for Crime and Justice Studies, Nutt said that illegal drugs…

Yesterday, I had the pleasure of attending a first-of-its kind hearing on the “legalization and regulation of marijuana,” held in the California Assembly Committee on Public Safety. The three-hour hearing included testimony from experts who told the legislature that arresting adults for marijuana is a gross waste of police resources and that the only way to control marijuana is to end prohibition and institute regulations for its sale. Witnesses advocating for reform included retired superior court…
