Regular low doses of THC dramatically boosted memory and learning in older mice, say scientists, who plan a clinical trial in humans later this year.

Researchers have come up with an unusual proposal to slow, or even reverse, the cognitive decline that comes with old age: small, daily doses of cannabis extract.

“This plant does not harm us!’’ dagga activist Myrtle Clarke declared as hundreds of people marched through the Cape Town CBD on Saturday.

Clarke‚ who along with her partner Jules Stobbs are known as the ‘’Dagga Couple’’‚ addressed cannabis enthusiasts near the Cape Peninsula University of Technology. A video of their address has been posted to their Facebook page.
