Abstract

Associations between cannabis use and cognitive functioning in cross-sectional studies of adolescents and young adults are small and may be of questionable clinical importance for most individuals. Furthermore, abstinence of longer than 72 hours diminishes cognitive deficits associated with cannabis use. Although other outcomes (eg, psychosis) were not examined in the included studies, results indicate that previous studies of cannabis in youth may have overstated the magnitude and persistence of cognitive deficits associated with use. Reported deficits may reflect residual effects from acute use or withdrawal. Future studies should examine individual differences in susceptibility to cannabis-associated cognitive dysfunction.

The Spice of Death: The Science behind Tainted “Synthetic Marijuana” - Experts describe how rat poison linked to a recent bleeding outbreak does its damage

Three people died and more than 100 have been sickened in the past few weeks after taking synthetic cannabinoids, human-made compounds that target the same brain receptors as marijuana. Symptoms documented by poison centers—first mostly in the Midwest, and now in Maryland—include unexplained bruising, coughing up blood, bleeding from the nose and gums, blood in urine and feces, and excessively heavy menstruation.

An ongoing investigation has identified a likely culprit in the blood of those affected: rat poison, specifically brodifacoum. (Scientific American, 17.04.2018)

USA. Illinois and Maryland Departments of Public Health Issue Alerts on Synthetic Cannabinoid Products

The Maryland Department of Health and Maryland Poison Center issued a memorandum yesterday to Emergency departments, emergency medical services, health care facilities, and local health departments reporting on a case in central Maryland in which a user of synthetic cannabinoids was hospitalized with symptoms similar to those experienced by cases in Illinois linked to synthetic cannabinoid product containing a rat poison that acts as an anticoagulant.

USA. Synthetic Cannabis Laced With Poison Linked to Severe Bleeding, CDC Warns

(...) From March 10 through April 5, 94 people have presented to emergency departments (89 in Illinois, two in Indiana, one in Maryland, one in Missouri, and one in Wisconsin) with potentially life-threatening vitamin K–dependent antagonist coagulopathy after using synthetic cannabinoids. Two individuals have died.

Laboratory testing confirmed that at least 18 individuals had been exposed to brodifacoum, a highly lethal vitamin K antagonist anticoagulant. It is used in commercial products for killing rodents and other pests. (Medscape, USA, 06.04.2018)
