Marijuana's Impact On Brain Function "Minimal," Study Says
Quote:Marijuana's Impact On Brain Function "Minimal," Study Says

London, United Kingdom: The consumption of cannabis, even long-term, has a "minimal" impact on brain function, according to a systematic literature review published online this week by the journal Psychological Medicine.

An international team of investigators from the United Kingdom, Spain, Brazil, Australia, and Switzerland conducted a systematic review of the effects of cannabis on brain structure and function.

Authors wrote, "We reviewed literature reporting neuroimaging studies of chronic or acute cannabis use published up until January 2009. ... Sixty-six studies were identified, of which 41 met the inclusion criteria. Thirty-three were functional (SPECT/PET/fMRI) and eight structural (volumetric/DTI) imaging studies. ... Only three of the structural imaging studies found differences between users and controls."

Investigators concluded, "Minimal evidence of major effects of cannabis on brain structure has been reported," noting that cannabis users and controls perform similarly on cognitive tasks.

According to a 2001 study published in the journal Archives of General Psychiatry, long-term cannabis smokers who abstained from pot for one week "showed virtually no significant differences from control subjects (those who had smoked marijuana less than 50 times in their lives) on a battery of 10 neuropsychological tests." Investigators added, "Former heavy users, who had consumed little or no cannabis in the three months before testing, [also] showed no significant differences from control subjects on any of these tests on any of the testing days."

For more information, please contact Paul Armentano, NORML Deputy Director, at: paul@norml.org. Full text of the study, "Neuroimaging in cannabis use: a systematic review of the literature," will appear in the journal Psychological Medicine.

Good find. I don't smoke pot but have plenty of friends and kin that do and I haven't noticed anything negative on their thinking. Just a little more chilled and munchie.I bet they can't say the same for booze and "legal " drugs.

Yup. It's hard for the state to control non-violent introspective, creative and giggly people, so they make the plant and it's possessions and cultivation illegal to control them. The same authorities cite that the "drug" is dangerous and that's why it's illegal. Well, this study is just one of many that show the complete opposite is true. There are minimal lasting cognitive effects on top of the tons of medical uses for cannabis.

The idiocy of the authorities and the general public make me feel like a pot toking alien that's stuck on the wrong world.
E.S. phone hoooome!!!

True. God forbid we have chilled out people using something that is 100% natural with thousands of uses that is easy to replenish. They want to go green, now theres a way to go green.
