TLDR
Early-onset chronic cannabis users exhibited poorer cognitive performance than controls and late-ONSet users in executive functioning, suggesting that chronic cannabis use, when started before age 15, may have more deleterious effects on neurocognitive functioning.Abstract:
Background Many studies have suggested that adolescence is a period of particular vulnerability to neurocognitive effects associated with substance misuse. However, few large studies have measured differences in cognitive performance between chronic cannabis users who started in early adolescence (before age 15) with those who started later. Aims To examine the executive functioning of individuals who started chronic cannabis use before age 15 compared with those who started chronic cannabis use after 15 andread more

TL;DR: Persistent cannabis use was associated with neuropsychological decline broadly across domains of functioning, even after controlling for years of education and cessation of cannabis use, suggestive of a neurotoxic effect of cannabis on the adolescent brain.

Acute and Chronic Effects of Cannabinoids on Human Cognition—A Systematic Review
TL;DR: This systematic review of empirical research published in the past decade on acute and chronic effects of cannabis and cannabinoids and on persistence or recovery after abstinence concludes that verbal memory, attention, and some executive functions may persist after prolonged abstinence, but persistence or Recovery across all cognitive domains remains underresearched.

Effects of Cannabis on Neurocognitive Functioning: Recent Advances, Neurodevelopmental Influences, and Sex Differences
TL;DR: The purpose of this review was to provide an update on research of cannabis’ acute and non-acute effects on neurocognition, with a focus on findings since 2007, and suggest and discuss how neurodevelopmental issues and sex differences may influence cannabis effects on neuroscience.

TL;DR: The dynamic anatomical sequence of human cortical gray matter development between the age of 4-21 years using quantitative four-dimensional maps and time-lapse sequences reveals that higher-order association cortices mature only after lower-order somatosensory and visual cortices are developed.
