The short-term and long-term effects of cannabis on cognition: recent advances in the field.

Cannabis intoxication temporarily impairs learning, memory, attentional control, and motor inhibition. Evidence for lasting cognitive deficits from long-term heavy use is mixed, partly because studies struggle to accurately measure cannabis exposure, control for lingering acute effects, and account for differences in cognitive tests and participant groups. Better research designs and multidisciplinary teamwork are needed to clarify these long-term effects.
