Cannabis and the brain: from threat to possible shield?
It impairs memory, attention and other cognitive functions. For years, the cannabis was painted as a enemy of the brain. But is it really like that?
A new study revolutionary, published in the prestigious magazine Brain and Behavior, refuted this false belief, showing that cannabis use may not only be harmless, but even associated with a lower cognitive decline over time.
Cannabis: "less cognitive decline" than non-users
“Men with a history of cannabis use recorded a lower cognitive decline" compared to those who had not used it.
This is the conclusion of researchers from three different departments at the University of Copenhagen, which they followed up further 5 thousand men for an average period of 44 years.
How did we arrive at these results?
Scholars have both analyzed gods cognitive tests conducted first at a young age and then again decades later, both the data traced the lifestyle and health of the participants.
In fact, as highlighted in the study, cannabis users "experienced slightly less cognitive decline than non-users and the association remained significant even when the potentials were checked confounding factors". Such as nutrition, physical activity and personal habits.
The breakthrough: no link between cannabis and cognitive decline
Among the results of the study that surprised the researchers is that among cannabis users:
"Nor the starting age of cannabis use nor frequent use were significantly associated with greater age-related cognitive decline."
The conclusion?
"NoWe have not seen any harmful effects significant effects of cannabis use on age-related cognitive decline".
Can cannabis protect against cognitive decline?
Against any prohibitionist theory, a new study has revealed that the recreational use of cannabis is even linked to one 96% decrease in the probability of perceiving subjective cognitive decline (DCS).
"The main conclusion is that cannabis could be protective for our cognition, but it's really critical to have longitudinal studies because this is just a snapshot of 2021 - said Professor Wong, who led the study.
They are therefore necessary other studies longitudinal studies to verify their long-term effects.
