Cannabidiol in Anxiety and Sleep : A Large Case Series, Scott Shannon et al., 2019

Cannabidiol in Anxiety and Sleep : A Large Case Series Scott Shannon, Nicole Lewis, Heather Lee,  Shannon Hughes, The Permanente Journal, 2019, 23, 18-041 doi.org/10.7812/TPP/18-041   ABSTRACT Context : Cannabidiol (CBD) is one of many cannabinoid compounds found in cannabis. It does not appear to alter consciousness or trigger a “high.” A recent surge in scientific publications has found preclinical and clinical evidence documenting value for CBD in some neuropsychiatric disorders, including epilepsy, anxiety, and schizophrenia. Evidence points toward a calming effect for CBD in the central nervous system. Interest in CBD as a treatment of a wide range of disorders has exploded, yet few clinical [...]

Cannabidiol (CBD) content in vaporized cannabis does not prevent tetrahydrocannabinol (THC)-induced impairment of driving and cognition, T.R. Arkell et al., 2019

Cannabidiol (CBD) content in vaporized cannabis does not prevent tetrahydrocannabinol (THC)-induced impairment of driving and cognition. Arkell T.R., Lintzeris N., Kevin R.C., Ramaekers J.G., Vandrey R., Irwin C., Haber P.S., McGregor I.S. Psychopharmacology (Berlin), 2019 DOI : 10.1007/s00213-019-05246-8 PMID : 31044290 Abstract BACKGROUND : The main psychoactive component of cannabis, delta-9-tetrahydrocannabinol (THC), can impair driving performance. Cannabidiol (CBD), a non-intoxicating cannabis component, is thought to mitigate certain adverse effects of THC. It is possible then that cannabis containing equivalent CBD and THC will differentially affect driving and cognition relative to THC-dominant cannabis. AIMS : The present study investigated and compared the effects of THC-dominant and [...]
