Investing in marijuana keeps looking better and better. Earlier this month researchers at Oxford University in the U.K. published the results of a bombshell study that found marijuana can have a positive impact on a brain in decline.
Doses of THC appear to improve memory and learning abilities in older mice suffering from cognitive decline. The implications for human sufferers of age-related cognitive decline, Alzheimer’s disease, Parkinson’s disease, and other forms of dementia are full of hope.
Researchers are studying THC (tetrahydrocannabinol) in a £10 million ($13 million) program to “identify new medical therapies through research into the molecular, cellular and systems mechanisms of cannabinoids.”
In the study, published by Nature Medicine, and publicized in a highly cited Newsweek article, “researchers led by Andreas Zimmer, from the University of Bonn, Germany, have shown how THC can provide significant benefits to mice when it comes to age-related cognitive decline.”
To study how THC might affect a brain in decline, researchers administered small doses of THC to mice at 2 months, 12 months, and 18 months- the latter two control groups representing mature and elderly mice.
The team did three experiments.
The first involved teaching mice to navigate a water maze. As expected mature and old mice performed worse than the young group. Then the team treated the older groups with THC, and amazingly found a significant improvement at the task. (Interestingly enough the young mice did much worse after receiving THC doses.)
The second test involved teaching mice to locate objects. Older mice given THC were able to perform as well as the younger mice that had not been administered with the drug.
The third test was related to partner recognition of other mice and also demonstrated the efficacy of THC in improved cognitive performance for mature and elderly mice.
The team wrote:
“Together, these results reveal a profound, long-lasting improvement of cognitive performance resulting from a low dose of THC treatment in mature and old animals.”
The Motley Fool, an Alexandria, Virginia-based financial services and investing company said Sunday that these findings should encourage investing in marijuana businesses:
“The marijuana industry, and marijuana stocks for that matter, have been expanding by leaps and bounds over the past two decades. What was once a completely taboo industry has become a thriving source of legal growth, at least in some states…
What studies like this do is really fan the flame of what might be possible with cannabis-based medicines. While many of the ongoing studies are considered informal in nature — i.e., they’re not being overseen by an accredited regulatory body like the U.S. Food and Drug Administration (FDA) — some developing pot-based drugs have really turned heads.”
