A recent study published in the Journal of Psychopharmacology suggests that using cannabis has widespread negative effects on many different types of memory. The findings provide evidence that getting high impairs everyday cognitive functions, like remembering to perform future tasks or recalling the exact sequence of past events. “It is well established in the empirical literature that acute cannabis intoxication is detrimental to memory,” said study author Carrie Cuttler, an associate professor at Washington State University and a co-director of WSU’s Cannabis Research Center. “However, the bulk of prior research examining the acute effects of cannabis on memory in humans has focused on a relatively narrow set of memory tests primarily verbal memory tasks, which involve recalling lists of words, and working memory tasks, which require temporarily holding and manipulating information in consciousness. “Far fewer studies have examined how cannabis affects other types of memory that are more relevant to everyday life. These include temporal order memory (remembering the order in which events occurred), prospective memory (remembering to perform tasks in the future), source memory (remembering where information came from), false memory (recalling information …
