Among cannabis users, neither age of initiation of cannabis use nor frequent use was significant.
Researchers at the Univerity of Copenhagen studied about the relationship between cannabis use and age-related cognitive decline.
The findings pointed out that there are no significant harmful effects of cannabis use on age-related cognitive decline. This is quite contrary to what was believed.
Meanwhile, a recent study found that low doses of Tetrahydrocannabinol (THC), the main active ingredient in cannabis, showed to reverse conventional signs of brain aging in mice.
Just a thought.
