Cannabis reverses aging processes in the brain
I'm not sure its wise to say "Cannabis" as a shorthand for "Low doses of THC."<p>The headline of the paper is: "A chronic low dose of Δ9-tetrahydrocannabinol (THC) restores cognitive function in old mice.<p><a href="https://www.nature.com/nm/journal/v23/n6/full/nm.4311.html"" rel="nofollow">https://www.nature.com/nm/journal/v23/n6/full/nm.4311.html"</a><p>Which is interesting, but you shouldn't take it to mean smoking is good for your brain. We already have some data to suggest that smoking cannabis, at least while young, is linked to cognitive decline.<p>"Persistent cannabis users show neuropsychological decline from childhood to midlife" (2012)<p><a href="http://m.pnas.org/content/109/40/E2657.full" rel="nofollow">http://m.pnas.org/content/109/40/E2657.full</a>
