This review aims to compare cognitive consequence between cannabis, and stimulants and heroin with regards to attention, memory and executive functions. The available studies using brain imaging techniques and neuropsychological tests show that acutely, all drugs create a disharmony in the neuropsychological network, causing a decrease of activity in areas responsible for short-term memory and attention, with the possible exception of heroin. Cannabis induces loss of internal control and… Expand
Cannabis Use and Cognitive Function
Prevalence rates for cannabis use are steadily increasing, particularly among adolescents and young adults, which constitute a major health concern. An extensive growing body of research hasExpand
Cognitive consequences of drug abuser: comparison with abuse of stimulants and opioid with regard to attention and working memory
Abstract Existence of disharmony in sustaining attention and working memory in stimulants abusers and opioids abusers in Iran is observable. The performance of tree group of people included 30 normalExpand
Discrete memory impairments in largely pure chronic users of MDMA
TLDR
Even largely pure chronic MDMA use is associated with decreased performance in declarative memory, while additional deficits in working memory and executive functions displayed by polydrug MDMA users are likely driven by stimulant co-use. Expand
Working memory and multi-tasking in paranoid schizophrenia with and without comorbid substance use disorder.
TLDR
The present study indicates severe working memory and multi-tasking deficits in schizophrenia which are, however, not exacerbated by comorbid addiction. Expand
Strategic control, consolidation and poly-drug use; the relative contributions to verbal memory impairment in recreational ecstasy users
Tests of verbal learning and memory have frequently been used to examine memory performance in frequent 3,4-methylendioxymethamphetamine (“ecstasy”) consumers, and meta-analyses have identifiedExpand
[Overgeneralization of autobiographical memory strategies in cannabis users and multiple psychoactive substance consumers].
TLDR
The results show that overgeneralization is a phenomenon observable in psychoactive substance consumers, whatever the type of substances used, which sets in progressively as the dependence develops, implying that this phenomenon could be underlined by several mechanisms. Expand
Does Cannabis Consumption Negatively Affect Cognition? A Review Of The Scientific Evidence
Objective: This review summarises the existing evidence on the effects that recreational and medical use of cannabis and cannabinoids have on cognitive performance. Methods: Databases (PubMed,Expand
Working Memory and Long-Term Abstinence from Substance Use
Cognitive impairment is a well-established consequence of long-term substance abuse, with stimulant and polysubstance abuse leading to the most detrimental deficits, especially in the area ofExpand
The effect of cannabis use on memory function: an update
TLDR
Future experimental and epidemiological studies that take into consideration individual differences, particularly previous cannabis history and demographic characteristics, but also the precise mixture of the ingredients of the consumed cannabis are necessary to clarify the magnitude and the mechanisms by which cannabis-induced memory impairments occur and to elucidate underlying neurobiological mechanisms.

Chronic MDMA (ecstasy) use, cognition and mood
TLDR
These results suggest that MDMA users exhibit difficulties in coding information into long-term memory, display impaired verbal learning, are more easily distracted, and are less efficient at focusing attention on complex tasks. Expand
Profiles of Cognitive Dysfunction in Chronic Amphetamine and Heroin Abusers
TLDR
The results indicate that chronic drug use may lead to distinct patterns of cognitive impairment that may be associated with dysfunction of different components of cortico-striatal circuitry. Expand
Differential effects of MDMA, cocaine, and cannabis use severity on distinctive components of the executive functions in polysubstance users: a multiple regression analysis.
TLDR
Results showed a differential impact of severity of MDMA abuse on working memory and abstract reasoning indices, of cocaine severity on an inhibitory control index and of cannabis on a cognitive flexibility index. Expand
Cognitive functioning of long-term heavy cannabis users seeking treatment.
TLDR
It is confirmed that long-term heavy cannabis users show impairments in memory and attention that endure beyond the period of intoxication and worsen with increasing years of regular cannabis use. Expand
Impaired executive function in male MDMA (“ecstasy”) users
TLDR
The present data suggest that a history of MDMA use selectively impairs executive function, and in male users, cognitive flexibility was impaired and increased perseverative behavior was observed. Expand
Differential impairments of selective attention due to frequency and duration of cannabis use
TLDR
The results suggest that a chronic buildup of cannabinoids produces both short- and long-term cognitive impairments, as well as two ERP measures known to reflect distinct components of attention affected differentially by duration and frequency of cannabis use. Expand
Differential effects of cocaine and cocaine alcohol on neurocognitive performance
TLDR
The concomitant use of cocaine and alcohol may have additive negative effects on the brain as compared to the use of only one of these two substances. Expand
Short-term memory impairment in cannabis-dependent adolescents.
TLDR
It is concluded that cannabis-dependent adolescents have selective short-term memory deficits that continue for at least 6 weeks after the last use of marijuana. Expand
Effects of marijuana on neurophysiological signals of working and episodic memory
TLDR
The results suggest that marijuana disrupted both sustained and transient attention processes resulting in impaired memory task performance, and in subjects most affected by marijuana a pronounced ERP difference between previously studied words and new distracter words was reduced, suggesting disruption of neural mechanisms underlying memory for recent study episodes. Expand
Contribution of cannabis and MDMA ("ecstasy") to cognitive changes in long-term polydrug users
TLDR
Cognitive/behavioural measures were used and the main finding was that cannabis users, whether or not they also used MDMA, showed significantly impaired memory function on word free-recall and on immediate and delayed story recall compared to non-users. Expand
