Study: Cannabis Use May Subside Effects of Aging


A recent study by German researchers at the University of Bonn and Hebrew University concluded that “a chronic low dose of THC restores cognitive function in old mice” and could prevent human brains from “slowing down” later in life.

The researchers gave mice of varying ages daily doses of THC for one month straight. While two-month-old mice lost cognitive skills, the 12-18-month-old mice demonstrated a “considerable performance boost, even putting them on par with younger mice who’d abstained.”

To arrive at this conclusion, the researchers tested the subject’s recognition of “familiar objects” and had the mice go through “a water maze in known and new configurations.” The group of elderly mice displayed no negative side effects from the THC while the younger mice lost cognitive skills.

All told, the older mice that consumed THC demonstrated noticeable improvements in test performance. The conclusion: a dose of THC a day boosts the endocannabinoid system and, if comparable in humans, could result in a better qualify of life for the elderly.

Given the promising findings, researchers plan to conduct a similar experiment on older “human brains” via a clinic trial sometime this year. Cannabis could very well help keep older brains sharper for a longer period of time, and one of the study’s co-authors, Andras Bilkei-Gorzo, said just that:

“If we can rejuvenate the brain so that everybody gets five to 10 more years without needing extra care then that is more than we could have imagined.”

Cannabis might just be a Sorcerer’s Stone for the elderly.

  1. Cannabis for all! Adult use of cannabis is finally gaining broader acceptance, and it’s a pleasure to see people finally realizing the benefits. GoFire is a vaporizer company looking for beta testers to help them refine their micro-dosing capable device. Interested parties can apply for consideration as #BetaPioneers at

  2. Low dose regime with edible cannabis oil would probably be in the 50mg range for a daily dose, this would be of ethanol extracted cannabis oil that has been decarboxylated. This is the amount most often cited in stories about daily “maintenance dosing.”

  3. I have been smoking weed for 43 years, daily. Grew up in Berkeley and was a young person at the height of the hippie revolution.
    Not trying to brag, but I am 69 years old, and people often think that I am about 40. (I am natural, no plastic surgery)
    A healthy diet, (veggie salads, smoothies, salmon, organic fruits, and vitamins) and exercise is imperative if you want to look and feel young. Lot’s and lot’s of water and, green tea.
    Hate to say it, but alcohol will age you faster than anything. (besides heroin, meth or alot of sun). Use sunblock, every single day, without fail. One of my clients told me that she got skin cancer and never sat in the sun. She was in her 50’s, and said that she only went from her house to her car, for decades. It is accumulative.
    But, getting back to “weed”. Love it, and will always smoke it. The only bad thing about it, is it can be costly.
