Micro doses of THC may provide a “SAFE and EFFECTIVE treatment for cognitive decline in aging humans” and could even REVERSE AGE-RELATED DECLINE, according to experimental research.

The beneficial effect of THC lasted for at least seven weeks after just one injection in the brains of adult mice, said the study, published in Neurobiology of Aging.

THC did not produce a high because of the low dose administered.

Larger and denser brains in THC-treated mice were discovered when compared with the brains of untreated older mice.

These important discoveries add to the evidence already found in studies on the brains of young and old mice.

What’s more, the brains of young mice were protected from various insults, including infection, when ultra-low doses of THC were administered.

Researchers looked at specific areas of the brain related to learning, understanding, and perception.

Images of  the “old”  brains were examined through Magnetic Resonance Imaging (MRI).

“Reversal of age-related cognitive impairments in mice by an extremely low dose of tetrahydrocannabinol” was published in Neurobiology of Aging in January 2018.
