Impact of cannabidiol on the acute memory and psychotomimetic effects of smoked cannabis: naturalistic study
TLDR
The antagonistic effects of cannabidiol at the CB1 receptor are probably responsible for its profile in smoked cannabis, attenuating the memory-impairing effects of THC. Expand
Acute Effects of Ketamine on Memory Systems and Psychotic Symptoms in Healthy Volunteers
TLDR
The data suggest that, in humans, ketamine produces a selective pattern of impairments to working, episodic, and procedural memory but not to perceptual priming, attention or aspects of executive functioning. Expand
Keep off the grass? Cannabis, cognition and addiction
TLDR
The current state of knowledge about vulnerability factors, the variations in types of cannabis, and the relationship between these and cognition and addiction are reviewed. Expand
Cognitive and subjective effects of mephedrone and factors influencing use of a 'new legal high'.
TLDR
Mephedrone impairs working memory acutely, induces stimulant-like effects in users and is associated with binge use, which might help to predict future trends in use of the many new psychoactive substances emerging on the internet. Expand
Effects of cannabidiol on schizophrenia-like symptoms in people who use cannabis
TLDR
Hair samples were analysed to examine levels of Δ9-THC and CBD in 140 individuals and three clear groups emerged: ’THC only’, ‘THC+CBD’ and those with no cannabinoid in hair, which provides evidence of the divergent properties of cannabinoids. Expand
Acute and chronic effects of ketamine upon human memory: a review
TLDR
This article reviews the existing literature on the effects of acute ketamine on the memory of healthy volunteers and of repeated doses of ketamine in recreational users and suggests that ketamine may differ from other classic amnestic drugs in impairing aspects of semantic memory. Expand
Ketamine use: a review.
TLDR
The implications of these findings are drawn out for treatment of ketamine-induced ulcerative cystitis in which interventions from urologists and from addiction specialists should be coordinated. Expand
Cannabidiol Attenuates the Appetitive Effects of Δ9-Tetrahydrocannabinol in Humans Smoking Their Chosen Cannabis
TLDR
The findings suggest that CBD has potential as a treatment for cannabis dependence and the acute modulation of the incentive salience of drug cues by CBD may possibly generalize to a treatment to other addictive disorders. Expand
Consequences of chronic ketamine self-administration upon neurocognitive function and psychological wellbeing: a 1-year longitudinal study.
TLDR
Findings imply that heavy use of ketamine is harmful to aspects of both cognitive function and psychological wellbeing. Expand
The Psychotomimetic States Inventory (PSI): Measuring psychotic-type experiences from ketamine and cannabis
TLDR
The Psychotomimetic States Inventory is a potentially useful measure of the nature and extent of the phenomenological effects of psychotropic drugs in schizophrenia-related research. Expand
