While the ongoing debate about the nature and duration of these effects recognizes mild cognitive impairment, the evidence for irreversibility of cognitive impairment and causal links with psychiatric illness is not conclusive. There is undoubtedly potential for impairment of respiratory functioning, but that will depend on lifetime load and in most cases is confounded with tobacco smoking. There is a [...]

Ramsey European Neuropsychopharmacology, 2019, 13, 56, 1–11 https://doi.org/10.1016/j.euroneuro.2019.03.010 Abstract Cannabis produces a broad range of acute, dose-dependent psychotropic effects. Only a limited number of neuroimaging studies have mapped these effects by examining the impact of cannabis on resting state brain neurophysiology. Moreover, how genetic variation influences the acute effects of cannabis on resting state brain function [...]

Bossong Journal of Clinical Medicine, 2019, 8, 1058 doi : 10.3390/jcm8071058 Abstract : The endogenous cannabinoid (eCB) system plays an important role in the pathophysiology of both psychotic disorders and substance use disorders (SUDs). The non-psychoactive cannabinoid compound, cannabidiol (CBD) is a highly promising tool in the treatment of both disorders. Here we review human clinical studies that investigated the ecacy of CBD treatment for schizophrenia, substance use disorders, and their comorbidity. In particular, we examined [...]

We previously showed that nabiximols (27 mg/ml Δ9-tetrahydrocannabinol (THC)/ 25 mg/ml cannabidiol (CBD), Sativex®) can decrease cannabis withdrawal symptoms. Here, we assessed in a pilot study the [...]
