“…Solowij et al 11 found that information processing evaluated by paced auditory serial addition test was worse in long-term cannabis users than in short-term users or no users. Frontal Assessment Test, a neurocognitive function test, showed worse performance of cannabis users when compared to The changes of the cognitive and psychomotor functions in the chronic cannabis users after a month of remission controls 39 . AMIPB-A and AMIPB-B, tests for evaluating information processing, assess working memory, attention, sustained attention, comparison, which are mainly the functions of premotor frontal region 28,32 .…”

ABS TRACT:The changes of the cognitive and psychomotor functions in the chronic cannabis users after a month of remission Objective: In our study, it is aimed to investigate impacts of cannabis use on information processing and psychomotor functions and to examine changes in the cognitive functions at the end of abstinence over a month. Method:The study was initiated with 34 volunteer participants using cannabis at least over two years, directed by a forensic unit. 34 persons were assessed at admission and were planned to assess after a month of remission. As 14 participants discontinued the study 20 participants only were assessed again at the end Results: There was no statistically significant difference between participants continue to the treatment and those discontinue in terms of sociodemographic and clinical characteristics. The participants discontinue were using more daily cannabis dose. The auditory reaction time of the group continue to the treatment decreased statistically significantly after a month whereas there was no statistically significant difference in the visual reaction time. The scores of the AMIPB-A and AMIPB-B were detected statistically higher after a month compared to admission. The score of the dominant hand FTT after a month was detected statistically higher than that in admission whereas there was no statistically significant difference in the non-dominant hand score. Conclusion:Improvements in scores of AMIP-A, AMIP-B, FTT and auditory reaction time after one month of quitting cannabis suggest that cannabis use may impair cognitive functions such as information processing, reaction time and motor functions. We suggest that future studies to assess cognitive functions after either a shorter (i.e. 1 week) or a longer (i.e. 2 months) period of cannabis abstinence in larger samples may provide further useful data about the relationship between cannabis use and cognitive functions.

“…Impaired performance may depend on extent of prior exposure, route of administration, dose delivered, and blood cannabinoid concentrations at baseline and after dosing (89). With regard to the chronic effects of cannabis, numerous studies reported null findings in case-control comparisons (46,54,66,81,95,98,110,111), whereas several others found cannabis-related deficits in heavy users (53,78,83,112), including adolescents (113), early-onset but not late-onset adult users (114), and older users (57), and associated with persistent use in a longitudinal study (60). Impaired executive function was evident despite intact performance on other cognitive tasks (48,82) and associated with self-reported problems related to cannabis use (115).…”

Cannabis use has been associated with impaired cognition during acute intoxication as well as in the unintoxicated state in long-term users. However, the evidence has been mixed and contested, and no systematic reviews of the literature on neuropsychological task-based measures of cognition have been conducted in an attempt to synthesize the findings. We systematically review the empirical research published in the past decade (from January 2004 to February 2015) on acute and chronic effects of cannabis and cannabinoids and on persistence or recovery after abstinence. We summarize the findings into the major categories of the cognitive domains investigated, considering sample characteristics and associations with various cannabis use parameters. Verbal learning and memory and attention are most consistently impaired by acute and chronic exposure to cannabis. Psychomotor function is most affected during acute intoxication, with some evidence for persistence in chronic users and after cessation of use. Impaired verbal memory, attention, and some executive functions may persist after prolonged abstinence, but persistence or recovery across all cognitive domains remains underresearched. Associations between poorer performance and a range of cannabis use parameters, including a younger age of onset, are frequently reported. Little further evidence has emerged for the development of tolerance to the acutely impairing effects of cannabis. Evidence for potential protection from harmful effects by cannabidiol continues to increase but is not definitive. In light of increasing trends toward legalization of cannabis, the knowledge gained from this body of research needs to be incorporated into strategies to minimize harm.

“…Reports indicate that cannabis users, and particularly those with CUDs, may be at increased risk for mortality [9,10], yet other studies present conflicting findings [11]. In addition, CUDs may be associated with deficits in cognitive functions such as executive functions, working memory and both immediate and delayed memory [12][13][14][15]. The evidence regarding the extent to which these deficits improve during abstinence is conflicting [16,17].…”
