“Cannabis ( Cannabis sativa/indica), also known as marijuana, has been used for medicinal and recreational purposes for millennia.

There has been a recent trend to legalize the use of cannabis, as illustrated by the recent legalization votes in numerous states in the United States and legislation in Canada to allow recreational cannabis use. With this increasing consumption of cannabis, dermatologists will see increased pressure to prescribe cannabis and will see the side effects of cannabis use with greater frequency.

There are several approved medical indications for cannabis use, including psoriasis, lupus, nail-patella syndrome, and severe pain. In addition, very preliminary studies have suggested cannabis and its derivatives might have use in acne, dermatitis, pruritus, wound healing, and skin cancer.

In this review, we summarize some of the studies and reports regarding the medicinal uses of cannabis in the dermatology clinic and some of the side effects that might present more often to dermatologists as the use of cannabis increases.”

Multiple Sclerosis and Related Disorders Home

“Spasticity is a common symptom of multiple sclerosis (MS) affecting about 80% of MS patients. Numerous lines of evidence suggest that spasticity due to its complexity is not adequately managed with conventional anti-spastic therapies. Therefore, in order to improve the outcomes for the majority of MS patients, alternative approaches are needed to be discovered. Over the last years, the use of cannabinoid compounds as a potential treatment for MS-related symptoms has aroused great interest, owing to encouraging preclinical and clinical studies. To date, Sativex, an oromucosal spray containing tetrahydrocannabinol and cannabidiol in approximately 1:1 ratio, is the only commercially available formulation containing cannabinoids used as add-on therapy for treatment of spasticity in adult MS patients who are not responding to conventional antispastic therapies.

METHODS:

Here, by performing a literature search, we provided an overview of the last decade of clinical evaluations as well as post-marketing studies about effectiveness and safety of Sativex in the management of MS-related spasticity.

RESULTS:

Sativex was proven effective in treating spasticity and also in improving the patient’s quality of life. In addition, a low incidence of adverse reactions Sativex-related supports the good safety profile and its tolerability.

CONCLUSION:

This review by recognizing the clinical effectiveness of Sativex in spasticity management, opened a new opportunity for many patients with spasticity resistant to common antispastic drugs.”

“Lower urinary tract dysfunctions (LUTDs) are commonly reported in multiple sclerosis (MS) patients and are mainly related to neurogenic overactive bladder (OAB).

The aim of this observational study was to assess the effect of a tetrahydrocannabinol-cannabidiol (THC/CBD) oromucosal spray on resistant OAB by means of clinical and instrumental tools.

The THC/CBD treatment successfully reduced the OAB symptoms.

THC/CBD oromucosal spray has shown to be effective in improving overactive bladder symptoms in MS patients demonstrating a favorable impact on detrusor overactivity.”

“The impact of marijuana on nonalcoholic fatty liver disease (NAFLD) is largely unknown. We studied the association between marijuana and NAFLD utilizing cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) from 2005-2014 and NHANES III (1988-1994).

RESULTS:

Of the 14,080 (NHANES 2005-2014) and 8,286 (NHANES III) participants, prevalence of suspected NAFLD and ultrasonographically-diagnosed NAFLD were inversely associated with marijuana use (p < 0.001). Compared to marijuana-naïve participants, marijuana users were less likely to have suspected NAFLD (odds ratio [OR]: 0.90, 95% confidence interval [CI]: 0.82-0.99 for past user; OR: 0.68, 95% CI: 0.58-0.80 for current user) and ultrasonographically-diagnosed NAFLD (OR: 0.75, 95% CI: 0.57-0.98 for current user) in the age, gender, ethnicity-adjusted model. On multivariate analysis, the ORs for suspected NAFLD comparing current light or heavy users to non-users were 0.76 (95% CI 0.58-0.98) and 0.70 (95% CI 0.56-0.89), respectively (P for trend = 0.001) with similar trends in ultrasonographically-diagnosed NAFLD (OR: 0.77, 95% CI: 0.59-1.00 for current user; OR: 0.71, 95% CI: 0.51-0.97 for current light user). In insulin resistance-adjusted model, marijuana use remained an independent predictor of lower risk of suspected NAFLD.

CONCLUSIONS:

In this nationally representative sample, active marijuana use provided a protective effect against NAFLD independent of known metabolic risk factors. The pathophysiology is unclear and warrants further investigation.”

Journal of Substance Abuse Treatment

“While marijuana use is prevalent among persons with HIV (PWH), few studies have examined the relationship between marijuana use and HIV treatment outcomes independent of alcohol and other drug use.

METHODS:

We conducted a prospective cohort study to examine the relationships between frequency of marijuana use and antiretroviral therapy (ART) adherence and viral suppression in patients enrolled in the Johns Hopkins HIV Clinical Cohort between September 2013 through November 2015 (N=1377). We categorized marijuana use as no use, none in the last 3months, monthly use or less, weekly/daily. Our outcomes of interest were use of ART, ≥90 ART adherence, and viral suppression (HIV1-RNA<200 copies). We conducted multivariable analyses to examine associations between the frequency of marijuana use and our treatment outcomes, using generalized estimating equations to account for repeated measures. Other independent variables of interest included alcohol use, other drug use, and depressive symptoms. Analyses were adjusted for age, race, sex and HIV acquisition risk factor.

RESULTS:

In multivariable analyses we found no statistically significant association between frequency of marijuana use and our treatment outcomes. Alcohol use, other drug use and depressive symptoms were associated with lower odds of ART adherence and viral suppression.

CONCLUSIONS:

In this sample of PWH in care, frequency of marijuana use independent of other substance use does not appear to be associated with negative HIV treatment outcomes. Our results indicate that unlike alcohol, other substances and depression, marijuana use may not be a barrier to the effective treatment of HIV.”

Current Rheumatology Reports

“The purpose of this study was to provide the most up-to-date scientific evidence of the potential analgesic effects, or lack thereof, of the marijuana plant (cannabis) or cannabinoids, and of safety or tolerability of their long-term use.

RECENT FINDINGS:

We found that inhaled (smoked or vaporized) cannabis is consistently effective in reducing chronic non-cancer pain.

Oral cannabinoids seem to improve some aspects of chronic pain (sleep and general quality of life), or cancer chronic pain, but they do not seem effective in acute postoperative pain, abdominal chronic pain, or rheumatoid pain.

The available literature shows that inhaled cannabis seems to be more tolerable and predictable than oral cannabinoids. Cannabis or cannabinoids are not universally effective for pain. Continued research on cannabis constituents and improving bioavailability for oral cannabinoids is needed. Other aspects of pain management in patients using cannabis require further open discussion: concomitant opioid use, medical vs. recreational cannabis, abuse potential, etc.”

Daily cannabis and reduced risk of steatosis in human immunodeficiency virus and hepatitis C virus co-infected patients (ANRS CO13-HEPAVIH).

Journal of Viral Hepatitis

“Liver steatosis is common in Human Immunodeficiency Virus (HIV) – Hepatitis C Virus (HCV) co-infected patients. Some recent studies have found that cannabis use is negatively associated with insulin resistance in the general population and in HIV-HCV co-infected patients.

Given the causal link between insulin resistance and steatosis, we hypothesized that cannabis use has a positive impact on steatosis.

Therefore, we aimed to study whether cannabis use in this population was associated with a reduced risk of steatosis, measured by ultrasound examination.

The ANRS CO13-HEPAVIH cohort is a French nationwide multicenter of HIV-HCV co-infected patients. Medical and socio-behavioral data from clinical follow-up visits and annual self-administered questionnaires were prospectively collected. A cross-sectional analysis was conducted using data from the first visit where both ultrasound examination data for steatosis (positive or negative diagnosis) and data on cannabis use were available. A logistic regression model was used to evaluate the association between cannabis use and steatosis. Among study sample patients (n=838), 40.1% had steatosis. Fourteen percent reported daily cannabis use, 11.7% regular use, and 74.7% no use or occasional use (“never or sometimes”).

Daily cannabisuse was independently associated with a reduced prevalence of steatosis (adjusted odds ratio [95%]=0.64 [0.42;0.99]; p=0.046), after adjusting for body mass index, hazardous alcohol consumption and current or lifetime use of lamivudine/zidovudine. Daily cannabisuse may be a protective factor against steatosis in HIV-HCV co-infected patients. These findings confirm the need for a clinical evaluation of cannabis-based pharmacotherapies in this population.”

“The treatment of medical conditions with cannabis and cannabinoid compounds is advancing.

Although there are numerous reports related to the genetic variations of the cannabinoid receptor, a lack of studies that examine the relationship between other pharmacogenetic markers and health outcomes currently exists.

Herein, we advocate for the legalization of marijuana in the United States in order to perform more randomized controlled trials to help elucidate the role of other pharmacogenetic targets and cannabis for use in clinical practice.”
