Acceptance of pharmaceutical cannabis substitution by cannabis using patients with schizophrenia Jan van Amsterdam, Jojanneke Vervloet, Gerdien de Weert, Victor J. A. Buwalda, Anna E. Goudriaan and Wim van den Brink Harm Reduction Journal, 2018, 15, 47, 1-4. Doi : 10.1186/s12954-018-0253-7 Abstract Background : Cannabis-smoking patients with a psychotic disorder have poorer disease outcomes than non-cannabis-smoking patients with poorest outcomes in patients smoking high-potency cannabis (HPC) containing high Δ9-tetrahydrocannabinol (THC) and low cannabidiol (CBD). Quitting cannabis smoking or substitution of HPC by cannabis variants containing less THC and/or more CBD may benefit these patients. The present study explores whether daily HPC-smoking patients with schizophrenia accept smoking [...]

Stith Medicines, 2018, 5, 86, 1-11. doi : 10.3390/medicines5030086 Abstract Background : Approximately 0.5% of the population is diagnosed with some form of schizophrenia, under the prevailing view that the pathology is best treated using pharmaceutical medications that act on monoamine receptors. Methods : We briefly review evidence on the impact of environmental forces, particularly the effect of autoimmune activity, in the expression of schizophrenic profiles and the role of Cannabis therapy for regulating immunological functioning. Results : A review of the literature shows that phytocannabinoid consumption may [...]

Parsons, Fábio Klamt CNS Drugs, 2018, 32, (Suppl 1), 1-16. Springer Nature Switzerland, Doi : 10.1007/s40263-018-0550-4 Abstract The endocannabinoid retrograde signaling pathway is widely expressed in the central nervous system, where it plays major roles in regulating synaptic plasticity (excitatory and inhibitory) through long-term potentiation and long-term depression. The endocannabinoid system (ECS) components—cannabinoid receptors, endocannabinoids and synthesis/degradation enzymes—are expressed and are functional from early developmental stages and throughout adolescent cortical development, regulating progenitor [...]

Stinchcomb, and Kimberly Nixon Pharmacology, Biochemistry and Behavior, 2013, 111, 120–127. doi : 10.1016/j.pbb.2013.08.013 Abstract Excessive alcohol consumption, characteristic of alcohol use disorders, results in neurodegeneration and behavioral and cognitive impairments that are hypothesized to contribute to the chronic and relapsing nature of alcoholism. Therefore, the current study aimed to advance the preclinical development of transdermal delivery of cannabidiol (CBD) for the treatment of alcohol-induced neurodegeneration. In experiment 1, 1.0%, 2.5% and 5.0% CBD gels were evaluated for neuroprotection. [...]

You’ll feel less high, they said. This common piece of advice fed to THC-shy consumers can effectively bring someone back down to earth. It works—sometimes. But new research shows there’s likely more nuance in the solution than we initially thought. Scientists found that a high dose of CBD dampened the effects of a THC high, but participants reported a stronger high when combined with low doses of CBD. CBD can either dampen an out-of-control high [...]
