In some cultures, it’s traditional for elders to smoke weed, a practice said to help them pass on knowledge. A study done by Andreas Zimmer at the university of Bonn, Germany seems to add truth to this tradtion. The investigators are studying the endocannabinoid system, which helps balance out our bodies’ response to stress. Mice whose endocannabinoid system don’t work properly age faster, leading Zimmer to investigate if stimulating the system may have the opposite effect. Zimmer’s team is now planning trials to see if these observations can be replicated in humans.
