A study has been released showing positive signs for us older potheads.
While the studies based on humans had less control than ones done on rodents, both point to a lack of long term adverse effects in cognition.
It seems that as long as the THC levels are relatively lower, humans over 50 years old don’t have much to worry about in terms of additional cognitive decline (beyond, you know, the natural kind).
Better-controlled rodent studies indicate that the relationship between ∆9-tetrahydrocannabinol (THC) and cognitive function in healthy aging depends on age and level of THC exposure. Extremely low doses of THC improved cognition in very old rodents. Somewhat higher chronic doses improved cognition in moderately aged rodents.
Too early to really draw any blanket conclusions from this, but yet another good sign that moderate marijuana use has a serious lack of harm attached. Keep your joints lit.
