The use of medical grade cannabis in Italy for drug-resistant epilepsy: a case series.

Posted on by

 “In Italy, medical grade cannabis (MGC) can be prescribed for different medical conditions, including drug-resistant epilepsy (DRE), once standard and approved therapies have failed, or caused non-tolerable side effects.

Here, we present a retrospective case series report of five patients with DRE who started therapy with MGC. Authorized ISO 9001:2008 pharmacies prepared MGC according to Italian laws. Olive oil extracts (OOEs) were prepared following standard extraction protocols, and cannabinoids were measured on each OOE to check for successful extraction.

After treatment with MGC, all patients reported a reduction in seizure frequency and severity, and some reported improved mood, sleep quality, and general well-being without relevant side effects.

Despite the small sample size and open-label nature of the data, we show that MGC may be successfully used to treat DRE. This is especially true when considering that no valid therapeutic option exists for these patients and that MGC was extremely well tolerated.”

Exploring cancer survivors’ attitudes, perceptions, and concerns about using medical cannabis for symptom and side effect management: A qualitative focus group study.

Posted on by

Complementary Therapies in Medicine“The purpose of this study is to gain a greater understanding of cancer survivors’ attitudes, perspectives, and concerns about medical cannabinoids (MCs) for cancer symptom and side effect management.

Using qualitative methods, we conducted four focus groups (n = 19) with cancer survivors recruited from a community-based cancer wellness center. Groups were audio-recorded and facilitated by experienced co-moderators who directed discussion using a semi-structured interview guide. Transcripts were coded using principles from Grounded Theory.

Analyses revealed the following ten themes and percentages of codes applied: 1) Attitudes & Beliefs (25.3%), 2) Access (17.1%), 3) Information (15.5%), 4) Concern (14%), 5) How MCs Helped (12.6%), 6) Comfort (4.3%), 7) Confusion (3.6%), 8) Trust/Distrust (3.1%), 9) Behaviors (2.3%), and 10) Support (2.2%).

Participants reported that MCs offer potential benefits for symptom management and side effect relief, especially in reducing and managing pain. Despite the growing number of states that are legalizing MCs, significant barriers exist that make knowledge and adequate access a challenge for many.”

Association between cannabis and the eyelids: A comprehensive review.

Posted on by

Publication cover image“Cannabis is the most consumed illicit drug worldwide. As more countries consider bills that would legalize adult use of cannabis, health care providers, including eye care professionals (ophthalmologists, optometrists), will need to recognize ocular effects of cannabis consumption in patients.

There are only 20 studies on the eyelid effects of cannabis usage as a medical treatment or a recreational drug.

These include: ptosis induction, an “eyelid tremor” appearance and blepharospasm attenuation.

Six articles describe how adequately dosed cannabis regimens could be promising medical treatments for blepharospasm induced by psychogenic factors.

The exact mechanism of cannabinoids connecting cannabis to the eyelids is unclear.

Further studies should be conducted to better understand the cannabinoid system in relation to the eyelid and eventually develop new, effective and safe therapeutic targets derived from cannabis.”

Cannabinoids and the endocannabinoid system in anxiety, depression, and dysregulation of emotion in humans.

Posted on by

Image result for ovid journal“This review is to summarize most recent evidence published in the last 18 months on medical and recreational use of cannabis and cannabinoids in relation to anxiety, depression (unipolar and bipolar), and dysregulation of emotions as part of posttraumatic stress disorders (PTSD) and emotionally instable personality disorders.

It also covers the investigation of endocannabinoids as potential biomarkers in these conditions. This is important with increasing medicinal use of cannabinoids and growing social tolerance towards recreational cannabis use.

RECENT FINDINGS:

There is some recent evidence suggesting cannabinoids, cannabidiol or cannabidiol-enriched cannabis preparations have anxiolytic properties. In addition, depression may be worsened by cannabis use, however, randomized controlled trials (RCT) are lacking.

New evidence also suggests that cannabidiol or cannabidiol-enriched cannabis use for PTSD and emotion regulation can induce hyporesponse to fear and stress. Further, several lines of evidence point to the endocannabinoid system as a key player in some of the reviewed disorders, in particular anxiety and PTSD.

SUMMARY:

The most recent evidence for a therapeutic use of cannabinoids in the reviewed conditions is weak and lacking well designed RCTs. However, there is some indication of the role of the endocannabinoid system in these conditions that warrant further studies.”

Medical Cannabis as an Effective Treatment for Refractory Symptoms of Paraneoplastic Stiff Person Syndrome.

Posted on by

Journal of Pain and Symptom Management Home“Stiff person syndrome (SPS) is a disorder characterized by fluctuating, progressive and painful spasms of the limbs, trunk and face. The condition is frequently associated with other diseases, including malignancies1. Up to 10% of SPS cases are paraneoplastic (PSPS) and occur with various types of cancer 2. SPS is thought to be immune-mediated, with up to 60% of patients demonstrating antibodies to glutamic acid decarboxylase (GAD), the rate-limiting enzyme for the production of the inhibitory neurotransmitter γ-aminobutyric acid (GABA).” https://www.ncbi.nlm.nih.gov/pubmed/31743746

Frequency of cannabis and illicit opioid use among people who use drugs and report chronic pain: A longitudinal analysis.

Posted on by

Image result for plos medicine“Ecological research suggests that increased access to cannabis may facilitate reductions in opioid use and harms, and medical cannabis patients describe the substitution of opioids with cannabis for pain management.

We aimed to investigate the longitudinal association between frequency of cannabis use and illicit opioid use among people who use drugs (PWUD) experiencing chronic pain.

The most commonly reported therapeutic reasons for cannabis use were pain (36%), sleep (35%), stress (31%), and nausea (30%). After adjusting for demographic characteristics, substance use, and health-related factors, daily cannabis use was associated with significantly lower odds of daily illicit opioid use (adjusted odds ratio 0.50, 95% CI 0.34-0.74, p < 0.001).

 

We observed an independent negative association between frequent cannabis use and frequent illicit opioid use among PWUD with chronic pain. These findings provide longitudinal observational evidence that cannabis may serve as an adjunct to or substitute for illicit opioid use among PWUD with chronic pain.”

https://www.ncbi.nlm.nih.gov/pubmed/31743343

“In conclusion, we found evidence to suggest that frequent use of cannabis may serve as an adjunct to or substitute for illicit opioid use among PWUD with chronic pain in Vancouver. The findings of this study have implications for healthcare and harm reduction service providers. In chronic pain patients with complex socio-structural and substance use backgrounds, cannabis may be used as a means of treating health problems or reducing substance-related harm. In the context of the current opioid crisis and the recent rollout of a national regulatory framework for cannabis use in Canada, frequent use of cannabis among PWUD with pain may play an important role in preventing or substituting frequent illicit opioid use.”

Efficacy and adverse event profile of cannabidiol and medicinal cannabis for treatment-resistant epilepsy: Systematic review and meta-analysis.

Posted on by

“This paper aimed to systematically examine the efficacy and adverse event (AE) profile of cannabidiol and medicinal cannabis by analyzing qualitative and meta-analytic data.

According to the results, a statistically meaningful effect of cannabidiol compared with placebo was observed (p < 0.00001). When comparing treatment with cannabidiol or medicinal cannabis, significance was not found for the AE profile (p = 0.74). As AEs for cannabidiol were more common under short-term than under long-term treatment (p < 0.00001), this approach was favorable in the long term.

Furthermore, cannabidiol is more effective than placebo, regardless of the etiology of epileptic syndromes and dosage.

Overall, the AE profile did not differ across treatments with cannabidiol or medicinal cannabis, though it did differ favorably for long-term than for short-term treatment.”

Short- and Long-Term Effects of Cannabis on Headache and Migraine.

Posted on by

“Use of cannabis to alleviate headache and migraine is relatively common, yet research on its effectiveness remains sparse.

We sought to determine whether inhalation of cannabis decreases headache and migraine ratings as well as whether gender, type of cannabis (concentrate vs. flower), THC, CBD, or dose contribute to changes in these ratings. Finally, we explored evidence for tolerance to these effects.

Archival data were obtained from StrainprintTM, a medical cannabis app that allows patients to track symptoms before and after using different strains and doses of cannabis. Latent change score models and multilevel models were used to analyze data from 12,293 sessions where cannabis was used to treat headache and 7,441 sessions where cannabis was used to treat migraine.

There were significant reductions in headache and migraine ratings after cannabis use.

Men reported larger reductions in headache than women and use of concentrates was associated with larger reductions in headache than flower. Further, there was evidence of tolerance to these effects.

Perspective: Inhaled cannabis reduces self-reported headache and migraine severity by approximately 50%. However, its effectiveness appears to diminish across time and patients appear to use larger doses across time, suggesting tolerance to these effects may develop with continued use.”

The Impact of Medical Marijuana Laws and Dispensaries on Self-Reported Health

Posted on by

 “Growing evidence suggests that medical marijuana laws have harm reduction effects across a variety of outcomes related to risky health behaviors. This study investigates the impact of medical marijuana laws on self-reported health using data from the Behavioral Risk Factor Surveillance System from 1993 to 2013. In our analyses we separately identify the effect of a medical marijuana law and the impact of subsequent active and legally protected dispensaries. Our main results show surprisingly limited improvements in self-reported health after the legalization of medical marijuana and legally protected dispensaries. Subsample analyses reveal strong improvements in health among non-white individuals, those reporting chronic pain, and those with a high school degree, driven predominately by whether or not the state had active and legally protected dispensaries. We also complement the analysis by evaluating the impact on risky health behaviors and find that the aforementioned demographic groups experience large reductions in alcohol consumption after the implementation of a medical marijuana law.”

Perceived Efficacy of Medical Cannabis in the Treatment of Co-Occurring Health-Related Quality of Life Symptoms.

Posted on by

 Publication Cover“For persons living with chronic conditions, health-related quality of life (HRQoL) symptoms, such as pain, anxiety, depression, and insomnia, often interact and mutually reinforce one another.

There is evidence that medical cannabis (MC) may be efficacious in ameliorating such symptoms and improving HRQoL.

As many of these HRQoL symptoms may mutually reinforce one another, we conducted an exploratory study to investigate how MC users perceive the efficacy of MC in addressing co-occurring HRQoL symptoms. We conducted a cross-sectional online survey of persons with a state medical marijuana card in Illinois (N = 367) recruited from licensed MC dispensaries across the state. We conducted tests of ANOVA to measure how perceived MC efficacy for each HRQoL symptom varied by total number of treated symptoms reported by participants.

Pain was the most frequently reported HRQoL treated by MC, followed by anxiety, insomnia, and depression. A large majority of our sample (75%) reported treating two or more HRQoL symptoms. In general, perceived efficacy of MC in relieving each HRQoL symptom category increased with the number of co-occurring symptoms also treated with MC. Perceived efficacy of MC in relieving pain, anxiety, and depression varied significantly by number of total symptoms experienced.

This exploratory study contributes to our understanding of how persons living with chronic conditions perceive the efficacy of MC in treating co-occurring HRQoL symptoms. Our results suggest that co-occurring pain, anxiety, and depression may be particularly amenable to treatment with MC.”
