A new study suggests cannabis compounds show early promise for healthy aging, though more research is needed. Reviewing 18 studies over 15 years, researchers found some strong anti-aging results in animal tests, but more mixed findings in human participants. While cannabis compounds like CBD and THC demonstrated links to longer lifespans, improved learning, and reduced inflammation in animals, the human data was less clear. Cannabis has shown potential to both protect against cognitive decline and impair memory function in people. The researchers caution against over-optimism, noting that overall health in old age depends on many factors beyond cannabis use, including diet, exercise, sleep, and stress management. They emphasize the need for larger, longer-term human studies to better understand the specific effects of cannabis on aging. (Science Alert)
