Differential effects of gestational Cannabis smoke and phytocannabinoid injections on male and female rat offspring behavior.

Our understanding of the implications of gestational Cannabis exposure (GCE) remains unclear as Cannabis use increases worldwide. Much of the existing knowledge of the effects of GCE has been gained from preclinical experiments using injections of isolated Δ-tetrahydrocannabinol (THC) at relatively high doses. Few investigations of the effects of GCE to smoke from the whole Cannabis flower have been conducted, despite this being the most common mode of human consumption.

High-THC Smoke Impairs Incidental Memory Capacity in Spontaneous Tests of Novelty Preference for Objects and Odors in Male Rats.

Working memory is an executive function that orchestrates the use of limited amounts of information, referred to as working memory capacity, in cognitive functions. exposure impairs working memory in humans; however, it is unclear whether facilitates or impairs rodent working memory and working memory capacity. The conflicting literature in rodent models may be at least partly because of the use of drug exposure paradigms that do not closely mirror patterns of human use.
