Study: Marijuana May Protect Against Alcohol Brain Damage

WASHINGTON, D.C. -- 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 describe as "unexpected," the binge-drinking/marijuana group had lower FA scores than the controls in only three of eight regions, and in seven regions the binge-drinking/marijuana group had higher scores -- indicating less damage -- than the binge drinkers who did not use marijuana.
    Brain white matter tracts were "more coherent in adolescents who binge drink and use marijuana than in adolescents who report only binge drinking," the researchers wrote. "It is possible that marijuana may have some neuroprotective properties in mitigating alcohol-related oxidative stress or excitotoxic cell death," as has already been shown in lab and animal studies.
    "This study suggests that not only is marijuana safer than alcohol, it may actually protect against some of the damage that booze causes," said Steve Fox, Marijuana Policy Project director of state campaigns and co-author of the new book, "Marijuana Is Safer: So Why Are We Driving People to Drink?" (which hit number 17 on the Amazon.com bestseller list). "It's far better for teens not to drink or smoke marijuana, but our nation's leaders send a dangerous message by defending laws that encourage the use of alcohol over marijuana."

Dear friends,
Earlier this month, we told the Obama administration to stop sending mixed messages on medical marijuana. The drug czar has responded, but he still has his facts wrong. Let's ask President Obama to set his drug czar straight on medical marijuana. In a recent news interview, drug czar Gil Kerlikowske tried to amend his claim that "marijuana is dangerous and has no medicinal benefit,â saying that he was referring only to smoked marijuana. That's not good enough, because itâs still not true. The science is clear: marijuana can be highly effective as a medicine when itâs smoked. For some patients, thatâs the easiest and most effective way to consume it, and the harms of smoking it pale compared to the benefits. The president has repeatedly said that science should trump politics. Heâs also acknowledged that marijuana can be an effective medicine. We hoped this drug czar would be different from his predecessors. We still hope so, but he needs to abandon the falsehoods and rhetoric of the past. Our job is to hold the White House and its appointees accountable both to fulfill the promises made by candidate Obama and to ensure that the lies of the drug war become a thing of the past. Write to the president today and ask him to make clear that politics will no longer trump science when it comes to medical marijuana. Sincerely, Bill Piper  |
