New Insight into Neurobehavioral Effects of Legalized Cannabis

Researchers have published one of the first studies to characterize the association between the consumption of legal cannabis and subsequent pharmacologic and neurobehavioral outcomes, with somewhat surprising results.

The study showed that although cannabis consumption did not affect most short-term neurobehavioral measures, it delayed recall memory and impaired balance.

The investigation also showed that users of much more potent cannabis concentrates actually demonstrated similar or lower levels of subjective drug intoxication and short-term impairment than their counterparts who used lower-potency forms of the cannabis flower.

“It does not appear that the potency being used matters that much,” senior investigator Kent E. Hutchison, PhD, told Medscape Medical News. “People seem to be titrating to a certain level of intoxication or a certain level of feeling high. And for some people that requires a lot of drug, and for other people not as much.”

“As a first study, this was very useful in the sense that nobody really knew the effects of high-potency cannabis products,” added Hutchison, a professor of psychology and neuroscience at the University of Colorado Boulder.

The study was published online June…
