Potential Mechanisms Influencing the Inverse Relationship Between Cannabis and Nonalcoholic Fatty Liver Disease: A Commentary.

Image result for Nutrition and Metabolic Insights“Nonalcoholic fatty liver disease (NAFLD) develops when the liver is unable to oxidize or export excess free fatty acids generated by adipose tissue lipolysis, de novo lipogenesis, or dietary intake. Although treatment has generally been centered on reversing metabolic risk factors that increase the likelihood of NAFLD by influencing lifestyle modifications, therapeutic modalities are being studied at the cellular and molecular level.

The endocannabinoid system has been of recent focus. The agonism and antagonism of cannabinoid receptors play roles in biochemical mechanisms involved in the development or regression of NAFLD. Exocannabinoids and endocannabinoids, the ligands which bind cannabinoid receptors, have been studied in this regard.

Exocannabinoids found in cannabis (marijuana) may have a therapeutic benefit. Our recent study demonstrated an inverse association between marijuana use and NAFLD among adults in the United States.

This commentary combines knowledge on the role of the endocannabinoid system in the setting of NAFLD with the findings in our article to hypothesize different potential mechanisms that may influence the inverse relationship between cannabis and NAFLD.” https://www.ncbi.nlm.nih.gov/pubmed/31308686

 Journal of Adolescent Health Home“The purpose of the study was to describe associations between employment and marijuana use among adolescents 2 years before passage of 2012 ballot initiative and 2 years after the implementation of retail recreational marijuana sales took place in Washington.

Working adolescents in all grades had higher prevalence of recent marijuana use compared with nonworking adolescents.

Working youth were more likely to use marijuana before and after Washington’s legalization of retail marijuana.”

Association of Marijuana Laws With Teen Marijuana Use

“In the United States, 33 states and the District of Columbia have passed medical marijuana laws (MMLs), while 10 states and the District of Columbia have legalized the recreational use of marijuana.

A 2018 meta-analysis concluded that the results from previous studies do not lend support to the hypothesis that MMLs increase marijuana use among youth, while the evidence on the effects of recreational marijuana laws (RMLs) is mixed.

Here, we report estimates of the association between the legalization of marijuana and its use, simultaneously considering both MMLs and RMLs.

Consistent with the results of previous researchers, there was no evidence that the legalization of medical marijuana encourages marijuana use among youth.

Moreover, the estimates reported in the Table showed that marijuana use among youth may actually decline after legalization for recreational purposes.

This latter result is consistent with findings by Dilley et al and with the argument that it is more difficult for teenagers to obtain marijuana as drug dealers are replaced by licensed dispensaries that require proof of age.”

“The most important two medicinal cannabinoids are Δ9 -tetrahydrocannabinol (THC) and cannabidiol (CBD).

The results observed in this study are useful for guiding future pharmacokinetic studies of medicinal cannabinoids, and for development of dosing guidelines for medical use of cannabis in the ‘real world’ setting.”

Distinct Functions of Endogenous Cannabinoid System in Alcohol Abuse Disorders.

British Journal of Pharmacology banner

“Δ9-tetrahydrocannabinol (Δ9 -THC), the principal active component in Cannabis sativa extracts such as marijuana, participates in cell signaling by binding to cell surface receptors. CB1 receptors (CB1 s) are present in both inhibitory and excitatory presynaptic terminals. CB2 receptors (CB2 s) found in neuronal subpopulations in addition to microglial cells and astrocytes and are present in both pre- and postsynaptic terminals.

Subsequent to endocannabinoid (eCB) system discoveries, studies have suggested that alcohol alters the eCB system and that the eCB system plays a major role in the motivation to abuse alcohol.

Preclinical studies have provided evidence that chronic alcohol consumption modulates eCBs and CB1 expression in brain addiction circuits. In addition, studies have further established the distinct function of the eCB system in the development of fetal alcohol spectrum disorders. This review provides a recent and comprehensive assessment of the literature related to the function of the eCB system in alcohol abuse disorders.”

“Chronic, therapy-resistant pruritus often fails to respond to standard measures so new therapeutic approaches are needed.

Recently, the expression of cannabinoid receptors on cutaneous sensory nerve fibers was described, so cannabinoid agonists seem a rational therapeutic option for pruritus.

RESULTS:

In 14/22 patients a good antipruritic effect could be documented. The average reduction in itch was 86.4%. The therapy was well-tolerated by all patients; neither burning burn nor contact dermatitis was observed.

CONCLUSIONS:

Topical cannabinoid agonists represent an new effective and well-tolerated therapy for refractory itching of various origins. Creams with a higher concentration may be even more effective with broader indications.”

Publication cover image“The present study investigates the potential effect of a Cannabis sativa L. ethanolic extract standardized in cannabidiol as antiinflammatory agent in the skin. The extract inhibited the release of mediators of inflammation involved in wound healing and inflammatory processes occurring in the skin. Cannabis extract and cannabidiol showed different effects on the release of interleukin-8 and vascular endothelial growth factor, which are both mediators whose genes are dependent on NF-κB. Our findings provide new insights into the potential effect of Cannabis extracts against inflammation-based skin diseases.” https://www.ncbi.nlm.nih.gov/pubmed/31250491

“While more than half of the respondents in both groups showed some acceptance toward the usage of cannabis for research purposes, there was a stronger tendency to accept the use of cannabis for medical purposes in the informed group. Since this acceptance was more often displayed by respondents who had adequate knowledge of the medical use of cannabis, this suggests that providing information on cannabis is useful in promoting acceptance. The result of the survey indicated that a portion of neurologists acknowledges the usefulness of cannabis, and that one’s receptivity toward cannabis can be improved if adequate information is provided about cannabis.”   https://www.ncbi.nlm.nih.gov/pubmed/31243253
