Frequent Cannabis Use Not Associated With Cognitive Declines In Working Memory, Selective Attention

Utrecht, Netherlands

Utrecht, the Netherlands: Frequent cannabis use is not associated with cognitive deficits in memory or attention, according to trial data published in the forthcoming issue of the journal Psychopharmacology.

Investigators at the Rudolf Magnus Institute of Neuroscience assessed brain function in "frequent but relatively moderate" cannabis users in the domains of working memory and selective attention using functional magnetic resonance imagining (fMRI).

"No evidence was found for long-term deficits in working memory and selective attention in frequent cannabis users after one week of abstinence" compared to non-using healthy controls, authors concluded. "Furthermore, cannabis users did not differ from controls in terms of overall patterns of brain activity in the regions involved in these cognitive functions."

Previous trials on cannabis use and cognition have reached similar conclusions. An October 2004 study published in the journal Psychological Medicine examining the potential long-term residual effects of cannabis on cognition in monozygotic male twins reported "an absence of marked long-term residual effects of marijuana use on cognitive abilities."

A 2003 meta-analysis published in the Journal of the International Neuropsychological Society also "failed to reveal a substantial, systematic effect of long-term, regular cannabis consumption on the neurocognitive functioning of users who were not acutely intoxicated," and a 2002 clinical trial published in the Canadian Medical Association Journal determined, "Marijuana does not have a long-term negative impact on global intelligence."

Ya know, we all ought to send a copy of that first NORML report to all of our doctors-especially those who don't recognise cannabis' benefits. I seem to recall someone was recently asking how to become an activist- here's a easy, yet potentially mind-changing way. Wouldn't that be fun- hundreds of doctors all getting this paper and learning that cannabis can help grow nerve cells, is neuroprotective, kills brain cancer, stops or slows nerve degeneration and does NOT mess with cognition! And with all those nice studies at the end of each section, they can't argue it's just a single study! I just printed out the first 4 pages( the rest is just comments). I'm sending mine anonymously. My doctor gets enough hassle from me as it is. Might send a few more to some other doctors, too. LOL

hehehe good idea SC. hehehe sending yours anonymously... to funny.

my cardiologist basically told me not to come back to see him anymore ... seems after smoking pot, my blood pressure dropped almost to normal, WITHOUT the 14-per-day prescription pills he had me on ... (must have messed up his Drug Company-provided trips to the Bahamas, or something) ... oh well, plenty of cardiologists where he came from ... :rolleyes:
