San Diego, CA: Compounds in cannabis may offset some of the adverse effects of alcohol on the adolescent brain, according to clinical trial data published online by The Journal of Studies on Alcohol and Drugs.

Investigators at the University of California at San Diego assessed the cognitive performance of 130 adolescents (65 with histories of heavy marijuana use, and 65 non-marijuana-using controls), ranging in age from 15.7 to 19.1 years. Authors reported that the use of marijuana appeared to moderate the adverse effects of alcohol on verbal learning and memory.

Researchers determined, "Regression models revealed that greater alcohol hangover symptoms predicted worse verbal learning and memory scores for non-marijuana users, but alcohol hangover symptoms were not linked to performance among marijuana users."

They concluded: "Results confirm previous studies linking adolescent heavy drinking to reduced verbal learning and memory performance. However, this relationship is not seen in adolescents with similar levels of alcohol involvement who also are heavy users of marijuana."

A previous study published in 2009 reported that binge drinkers who also used cannabis experienced significantly less white matter damage to the brain as compared to subjects who consumed alcohol alone.

"Binge drinkers who also use marijuana did not show as consistent a divergence from non-users as did the binge drink-only group," investigators concluded. "[It is] possible that marijuana may have some neuroprotective properties in mitigating alcohol-related oxidative stress or excitotoxic cell death."

Commenting on the findings, NORML Deputy Director Paul Armentano said, "Alcohol and cannabis appear to have contrasting effects on the human brain," he said. "Ethanol is clearly toxic to healthy and developing cells whereas moderate doses of cannabinoids appear to be relatively non-toxic and possibly even neuroprotective."

Why is it always California pushing for legalization yet no other country / state is really that interested to

California has always been the cornerstone of counterculture and introducing new things to our society. It (CA) does something than over a prolonged period of time other, more liberal states follow suit, while the more conservative states do everything in their power to do the opposite of California. If you want new and exciting things thats the place to be.

well, the Czech republic recently de-criminalized cannabis, and it's been de-crim in Holland for quite a while, as with Portugal.

California does have a conservative underbelly though, which may end up showing come election time.
