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.

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 in Colorado, more than 70 percent of voters in the tiny ski town of Breckenridge voted to remove city-level criminal penalties for possession of up to one ounce of marijuana for adults over 21. While possession of any amount is still illegal under state law, the citizens of Breckenridge have undoubtedly sent a message to lawmakers in Colorado—and around the country—by taking this first and necessary step toward the end of marijuana prohibition.

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 California-based Center for Juvenile and Criminal Justice (CJCJ) took a long look at trends for marijuana arrests in the state and revealed some disturbing information. In its recent report to the California Legislature, CJCJ showed that the arrest rate for marijuana possession has skyrocketed in California – up 127% – between 1990 and 2008. But during the same period, arrests for all other offenses in California decreased by 40% – including other drug possession, which sank by nearly 30%. The arrest rate for marijuana sales and manufacturing even decreased 21% during this period.

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. [Read more →]

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 that “officials must make sure that San Diego’s medical marijuana patients have convenient access to their medicine in the city.” 70% support regulating the city’s medical marijuana collectives in some way, while only 9.5% support banning them (3% said they didn’t need any regulations). The poll also collected other interesting information about how San Diegans view medical marijuana sales. Read more about it here.

This poll should send a firm message to San Diego County District Attorney Bonnie Dumanis, who just last month ordered a series of shocking raids on local medical marijuana patients and suppliers.

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 terpenoids, that are actually of interest.

A second possible flaw is that the researchers considered all “byproducts” – defined as substances other than cannabinoids –  together. They didn’t analyze precisely what they were, lumping bad stuff like the toxic combustion products contained in smoke with potentially beneficial plant compounds like those terpenoids mentioned above. That puts the finding that fewer byproducts were produced at 230 degrees Celsius than were produced at lower temperatures in a somewhat different perspective: We don’t know if the same byproducts were produced at 230 degrees as were produced at lower temperatures – and what’s in that mixture could be just as important as how much of it there is.

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. [Read more →]

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 judge James P. Gray and former San Francisco district attorney Terence Hallinan – both of whom have seen the futility of marijuana prohibition firsthand from inside the criminal justice system. [Read more →]
