Cannabis May Help Improve Cognitive Abilities As You Age

One of the biggest misconceptions about cannabis is that it makes you stupid. The way that stoners are portrayed in popular culture doesn’t do much to dispel this. Aging stoners in movies and TV are usually goofy looking old hippie types that dispense cliched one liners–think Tommy Chong’s character in That 70’s Show. He was funny, but he was a total dumb ass. It’s time to retire this stereotype because it turns out that cannabis may help you turn into a wise old sage after all. New research shows that cannabis may help improve cognitive abilities as you age.

THC can Actually Improve Memory

Researchers at the University of Bonn Institute of Molecular Psychiatry in Germany have discovered that low doses of THC have improved learning abilities and memory in aging mice. The key here is low doses, so don’t smoke yourselves into a coma. Researchers administered low doses of THC to mice of 2,12, and 18 months. The results were surprising. THC impaired cognitive abilities, such as learning and memory in the youngest mice, but did the opposite with the old (12-18 months-old) mice.

THC is not Good for Young Brains, However

According to the researchers, “The same treatment rejuvenated old brains, whereas it made the young brains old. The reason of this phenomenon is that the activity of cannabinoid system declines in aging. In old animals, THC treatment restored the failing cannabinoid system activity, whereas it overactivated the normally functioning cannabinoid system in young animals.” Can we retire that goofy old stoner stereotype, yet?

Wait, it gets more interesting. Apparently what THC did to the brains of the older mice was it “restored hippocampal gene transcription patterns such that the expression profiles of THC-treated mice aged 12 months closely resembled those of THC-free animals aged 2 months,” according to the researchers. Next, the team hopes to conduct clinical trials on elderly participants.

I’m over the age of 25 and my brain has stopped developing, so that’s good news for me. *lights up*

    I have smoked marijuana in moderation over the past 45 years. I advanced well in my career, topped out in my field, retired. I have been married for 40 years, to one Woman. Life has been an amazing journey of discoveries, experiences and positive personal growth. I shall not claim any one thing that has been, nor is, greater than any other in determining my own value, substance, character and integrity. However, I know that I have thrived as best one can in living out a life in/with, meaning/purpose, to love and be loved… all the while, enjoying every moment of the quality time marijuana afforded me, which would include reflection and insight, therefore, enriching my own qualities, substance and integrity.
    One may always stop, and think but a moment, considering what/how you will experience life through the point of view you wish to take (about anything under the Sun).
    To quote Manly P Hall; “A Man’s/Woman’s status in the natural world is determined by the quality of their thinking.” Let them ‘read’ who can-
    To live a Lawful life is a peaceful, rewarding life.
    -‘The lips of wisdom are closed, except to the ears of understanding’-
    May you be always mindful of your conduct-
    Think well, live well, be well-
    Move in stealth and wit seeking Truth-
