Medical Marijuana Laws Reduce Prescription Medication Use In Medicare Part D.

Posted on July 8, 2016 by David

Health Affairs

“Legalization of medical marijuana has been one of the most controversial areas of state policy change over the past twenty years. However, little is known about whether medical marijuana is being used clinically to any significant degree. Using data on all prescriptions filled by Medicare Part D enrollees from 2010 to 2013, we found that the use of prescription drugs for which marijuana could serve as a clinical alternative fell significantly, once a medical marijuana law was implemented. National overall reductions in Medicare program and enrollee spending when states implemented medical marijuana laws were estimated to be $165.2 million per year in 2013. The availability of medical marijuana has a significant effect on prescribing patterns and spending in Medicare Part D.” http://www.ncbi.nlm.nih.gov/pubmed/27385238

Medical Marijuana for Epilepsy?

Posted on July 5, 2016 by David

“Treatment-refractory epilepsy remains an important clinical problem. There is considerable recent interest by the public and physicians in using medical marijuana or its derivatives to treat seizures. The endocannabinoid system has a role in neuronal balance and ictal control. There is clinical evidence of success in diminishing seizure frequencies with cannabis derivatives, but also documentation about exacerbating epilepsy or of no discernible effect. There are lay indications and anecdotal reports of success in attenuating the severity of epilepsy, but without solid investigational corroboration. Marijuana remains largely illegal, and may induce adverse consequences. Clinical applications are not approved, thus are restricted and only recommended in selected treatment unresponsive cases, with appropriate monitoring.”

Are medical marijuana users different from recreational users? The view from primary care.

Posted on June 2, 2016 by David

“Marijuana is currently approved for medical use in 23 states. Both clinicians and the lay public have questioned whether users of marijuana for medical purposes are different from users of marijuana for recreational purposes.

This study examined similarities and differences in important clinical characteristics between users of medical marijuana and users of recreational marijuana.

There was no significant difference between medical and recreational users in the percentage using marijuana with at least two additional substances.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE:

Although our results suggest that there are few distinct differences between medical and recreational users of marijuana, the differences observed, while mostly very small in effect size, are consistent with at least some medical users employing marijuana to relieve symptoms and distress associated with medical illness.”

[MEDICAL CANNABIS – A SOURCE FOR A NEW TREATMENT FOR AUTOIMMUNE DISEASE?].

Posted on May 25, 2016 by David

“Medical uses of Cannabis sativa have been known for over 6,000 years. Nowadays, cannabis is mostly known for its psychotropic effects and its ability to relieve pain, even though there is evidence of cannabis use for autoimmune diseases like rheumatoid arthritis centuries ago. The pharmacological therapy in autoimmune diseases is mainly based on immunosuppression of different axes of the immune system while many of the drugs have major side effects. In this review we set out to examine the rule of Cannabis sativa as an immunomodulator and its potential as a new treatment option. In order to examine this subject we will focus on some major autoimmune diseases such as diabetes type I and rheumatoid arthritis.”

The Use of Medical Marijuana in Cancer.

Posted on May 25, 2016 by David

“The use of medical marijuana in cancer care presents a dilemma for both patients and physicians. The scientific evidence is evolving, yet much of the known information is still insufficient to adequately inform patients as to risks and benefits. In addition, evidence-based dosing and administration information on medical marijuana is lacking. Medical marijuana is now legal, on some level, in 24 states plus the District of Columbia, yet is not legal on the federal level. This review addresses the current state of the research, including potential indications, risks and adverse effects, preliminary data on anticancer effects, as well as legal and quality issues. A summary of the clinical trials underway on medical marijuana in the oncology setting is discussed.”

Pain, Cannabis Species, and Cannabis Use Disorders.

Posted on May 15, 2016 by David

“The purpose of this study was to examine whether individuals who used medical cannabis for chronic pain were at increased risk for cannabis use problems compared with individuals who used medical cannabis for other reasons (e.g., anxiety, insomnia, and muscle spasms).

An additional aim was to determine whether individuals who used cannabis for chronic pain, as well as those who reported greater within-group pain levels, demonstrated a species preference (i.e., sativa, indica, hybrids) and the extent to which species preference was associated with cannabis use problems.

RESULTS:

Individuals who used cannabis to manage chronic pain experienced fewer cannabis use problems than those who did not use it for pain; among those who used it for pain, the average pain level in the past week was not associated with cannabis use problems. Furthermore, individuals who used cannabis for chronic pain were more likely to use indica over sativa. Preference for indica was associated with fewer cannabis use problems than preference for hybrid species.

CONCLUSIONS:

Individuals who use cannabis to manage chronic pain may be at a lower risk for cannabis use problems, relative to individuals who use it for other indications, potentially as a function of their species preference.”

Medical marijuana use in head and neck squamous cell carcinoma patients treated with radiotherapy.

Posted on March 24, 2016 by David

Supportive Care in Cancer

“The purpose of the study was to better understand why patients with history of head and neck cancer (HNC) treated with radiotherapy are using medical marijuana (MM).

RESULTS:

There was a 100 % response rate. Median time from treatment was 45 months (21-136 months). Most patients smoked marijuana (12 patients), while others reported ingestion (4 patients), vaporizing (3 patients), and use of homemade concentrated oil (1 patient). Six patients reported prior recreational marijuana use before diagnosis. MM provided benefit in altered sense, weight maintenance, depression, pain, appetite, dysphagia, xerostomia, muscle spasm, and sticky saliva.

CONCLUSIONS:

HNC patients report MM use to help with long-term side effects of radiotherapy.”

Medical Marijuana Use in Oncology: A Review.

Posted on March 19, 2016 by David

“Medicinal marijuana use is currently legal in 23 states and the District of Columbia. As more states approve marijuana use for medical indications, physicians will be asked by their patients for more information regarding the risks and benefits of use. This article reviews the history, adverse effects, and proposed mechanisms of action of marijuana and summarizes the available literature regarding symptom relief and therapeutic value in patients with cancer.

OBSERVATIONS:

Marijuana in oncology may have potential for use as an antiemetic, for refractory cancer pain, and as an antitumor agent. However, much of the data are based on animal data, small trials, or are outdated.

CONCLUSIONS AND RELEVANCE:

More research is needed in all areas related to the therapeutic use of marijuana in oncology.”

Medical marijuana laws and adolescent marijuana use in the USA from 1991 to 2014: results from annual, repeated cross-sectional surveys.

Posted on February 21, 2016 by David

“Our findings, consistent with previous evidence, suggest that passage of state medical marijuana laws does not increase adolescent use of marijuana.”

Prevalence of marijuana use does not differentially increase among youth after states pass medical marijuana laws: Commentary on and reanalysis of US National Survey on Drug Use in Households data 2002-2011.

Posted on February 21, 2016 by David

“There is considerable interest in the effects of medical marijuana laws (MML) on marijuana use in the USA, particularly among youth. The article by Stolzenberg et al. (2015) “The effect of medical cannabis laws on juvenile cannabis use” concludes that “implementation of medical cannabis laws increase juvenile cannabis use”. This result is opposite to the findings of other studies that analysed the same US National Survey on Drug Use in Households data as well as opposite to studies analysing other national data which show no increase or even a decrease in youth marijuana use after the passage of MML. We provide a replication of the Stolzenberg et al. results and demonstrate how the comparison they are making is actually driven by differences between states with and without MML rather than being driven by pre and post-MML changes within states. We show that Stolzenberg et al. do not properly control for the fact that states that pass MML during 2002-2011 tend to already have higher past-month marijuana use before passing the MML in the first place. We further show that when within-state changes are properly considered and pre-MML prevalence is properly controlled, there is no evidence of a differential increase in past-month marijuana use in youth that can be attributed to state MML.”
