Study: Pot tied to ... er, I forgot
From Reuters:NEW YORK (Reuters Health) - People who regularly smoke marijuana may find their memories growing hazy over time, a study published Monday suggests.
In a study of long-term and shorter-term marijuana users, researchers in Greece found that both groups performed more poorly on tests of memory, attention and other cognitive abilities than a comparison group who'd only occasionally used the drug.
Long-term users - who'd smoked four or more joints per week for at least 10 years - showed the greatest deficits.
The findings, published in the journal Neurology, add to the conflicting body of research on the effects of marijuana on the brain. While many studies have suggested that long-time pot smoking dulls memory, attention span and mental acuity, some have found no large differences in these skills between marijuana users and non-users.
