cannabis

roberts et al 2019

Results suggested that cannabis influences that motivational factors that lead to the initiation of eating and the hedonic factors implicated in encouraging and maintaining eating

• the novel Cannabis eating experience questionnaire supports anecdotal accounts of the influence of cannabis on eating behaviours

lorenzetti et al 2019 review evidence

most consistent findings in the literature on neuroadaptation from cannabis use was:

• differences in neuroanatomy in hippocmapus, amygdala, prefrontal cortex and cerebellum - all areas with high density of CB1 receptors

  • these alterations are correlated with heaver cannabis use

• some studies found a lack of neuroanatomical differences between cannabis users and controls

lorenzetti et al 2019 meta analysis evidence

Regular cannabis was associated with reduced volume sizes of the hippocampus and orbitofrontal cortex

• brain regions thought to underlie memory and reward processes relevant to the cause of substance dependence

schreiner and dunn (2012) meta analysis

no significant effect of cannabis on global cognitive function or individual domains of executive function, attention, recall, learning, motor effects, perceptual effects, reaction or verbal language fluency in cannabis users following 25 day minimum abstinence

• suggests that exhibited cognitive deficits in cannabis users could be attributed to residual intoxication or withdrawal = potential for recovery of cognitive deficits
