Neuropsychological performance in long-term cannabis users.
TLDR
Some cognitive deficits appear detectable at least 7 days after heavy cannabis use but appear reversible and related to recent cannabis exposure rather than irreversible andrelated to cumulative lifetime use. Expand

TLDR
The cardiovascular and subjective effects of cannabis are blocked by rimonabant, the first CB-1 cannabinoid-receptor antagonist, documenting thatCB-1 receptors mediate these effects of smoked cannabis in humans. Expand
Synthetic cannabinoids: epidemiology, pharmacodynamics, and clinical implications.
TLDR
A comprehensive review, based on a systematic electronic literature search, of SC epidemiology and pharmacology and their clinical implications is presented, showing in vitro and animal in vivo studies show SC pharmacological effects 2-100 times more potent than THC. Expand
Blood cannabinoids. I. Absorption of THC and formation of 11-OH-THC and THCCOOH during and after smoking marijuana.
TLDR
This study provides the first complete pharmacokinetic profile of the absorption of THC and appearance of metabolites during marijuana smoking, which has implications for understanding the mechanisms underlying the performance-impairing effects of marijuana, as well as for aiding forensic interpretation of cannabinoid blood levels. Expand
Matrix effect in bio-analysis of illicit drugs with LC-MS/MS: Influence of ionization type, sample preparation, and biofluid
TLDR
The results indicated that both ionization types showed matrix effect, but ESI was more susceptible than APCI, while SPE was necessary for extensive clean up of plasma prior to LC-APCI-MS/MS. Expand
Reversible and regionally selective downregulation of brain cannabinoid CB1 receptors in chronic daily cannabis smokers
TLDR
Reversible and regionally selective downregulation of brain cannabinoid CB1 receptors in human subjects who chronically smoke cannabis is shown, using positron emission tomography imaging, for the first direct demonstration of cortical cannabinoids CB1 receptor downregulation as a neuroadaptation that may promote cannabis dependence in human brain. Expand
Early-onset cannabis use and cognitive deficits: what is the nature of the association?
TLDR
Early-onset cannabis users exhibit poorer cognitive performance than late-ONSet users or control subjects, especially in VIQ, but the cause of this difference cannot be determined from the data. Expand
Cannabis effects on driving skills.
TLDR
Evidence suggests recent smoking and/or blood THC concentrations 2-5 ng/mL are associated with substantial driving impairment, particularly in occasional smokers, and future cannabis-and-driving research should emphasize challenging tasks, such as divided attention, and include occasional and chronic daily cannabis smokers. Expand
Plasma Pharmacokinetics of 3,4-Methylenedioxymethamphetamine After Controlled Oral Administration to Young Adults
TLDR
MDMA plasma pharmacokinetic data for the first time from blacks and females as well as measurement of HMMA and HMA concentrations after low and high MDMA doses and more frequent and extended plasma sampling than in prior studies are presented. Expand
