Persistent cannabis use linked to neurophysiological decline??

Here's the study: http://www.pnas.org/content/early/2012/08/22/1206820109

Any comments? Seems fishy to me.

Wouldn't doubt it for a second. Perhaps not low-dose users though.

Quite a few stoners I know are not mentally sharp to say the least. Perhaps this is only because they are constantly stoned.

Anybody have any further links to studies regarding neuroprotective or neurotoxic effects of cannabinoids?
