The latest review, published in Philosophical Transactions of the Royal Society B, suggests that activating the brain’s cannabinoid system may trigger a sort of anti-oxidant cleanse, removing damaged cells and improving the efficiency of the mitochrondria, the energy source that powers cells, ultimately leading to a more robustly functioning brain.

Previous studies have linked cannabinoids to increased amounts of brain-derived neurotrophic factor (BDNF), a substance that protects brain cells and promotes the growth of new ones. Since new cell growth slows or stops during aging, increasing BDNF could potentially slow the decline in cognitive functions.
