Marijuana & Memory

A daily puff of a compound like marijuana, the plant blamed for ruining
potheads' recall, might help maintain memory in old age, researchers who
tried it on rats reported today at a neuroscience meeting.

Elderly rats remembered their way around a swimming pool and could find
hidden resting spots after Yannick Marchalant and his colleagues at Ohio
State University gave them a compound that mimics the effect of marijuana on
the brain's cannabis receptors. The marijuana-like drug, known as
WIN-55212-2, spurred new brain cell growth and reduced inflammation, the
researchers said.
