As you know, Key ingredient staves off marijuana memory loss .. teensy bit ..
Cannabis composition determines effects on the brain. The subjects were divided into groups of high (samples containing more than 0.75% cannabidiol) and low (less than 0.14%) cannabidiol exposure, and the data were filtered so that their THC levels were constant. Analysis showed that participants who had smoked cannabis low in cannabidiol were significantly worse at recalling text than they were when not intoxicated. Those who smoked cannabis high in cannabidiol showed no such impairment.
The results suggest that cannabidiol can mitigate THC's interference with memory formation.
