Review: Cannabinoids Are an “Adequate Potential Treatment Option” for Fibromyalgia Patients

Fairfield, CA: Human trials indicate that the use of either whole-plant cannabis or cannabinoids can improve various symptoms in patients with fibromyalgia (FM) and that they possess an adequate safety profile for use in treatment, according to the findings of a literature review published in the journal Cureus.

Investigators affiliated with the California Institute of Behavioral Neurosciences and Psychology reviewed 22 scientific papers specific to the use of either cannabis or synthetic cannabinoids in FM patients.

Authors concluded: “[T]he data suggest that the use of cannabinoids and cannabis carries limited side effects in the treatment of FM, and they can also improve some common and debilitating symptoms associated with FM, thus making them an adequate potential treatment option, when other treatment lines have been exhausted.”

Cannabis use is frequently reported by patients with fibromyalgia, and the results of several human trials indicate that cannabinoids provide therapeutic relief to patients with fibromyalgia. Most recently, observational trial data published in February reported that the long-term use of various types of cannabis preparations was associated with significant improvements in pain and other symptoms in patients with refractory fibromyalgia.

Top Federal Drug Official Acknowledges that Adult-Use Marijuana Legalization Hasn’t Led to Jumps in Adolescent Use

Washington, DC: The enactment of statewide laws regulating the adult-use cannabis market has not led to an increase in the percentage of young people experimenting with the plant, according to comments made recently by Nora Volkow, Director of the US National Institute on Drug Abuse.

Speaking on a podcast hosted by Ethan Nadelmann, the former Director of the Drug Policy Alliance, Volkow admitted that she had initially expressed concerns that legalization would lead to an increase in the prevalence of adolescents consuming cannabis. Thus far, however, she said, “Overall, it hasn’t.”

To date, dozens of federal and state-specific surveys have failed to identify any independent link between the legalization of cannabis for either adult-use or medical purposes and any rise in the percentage of teens using it. Moreover, data published in 2019 in the journal JAMA Pediatrics reported that the enactment of laws regulating the use of cannabis by adults is associated with declines in self-reported marijuana use by young people. Separate data compiled by the US Centers for Disease Control has reported that the number of adolescents admitted to drug treatment programs for marijuana-related issues has fallen precipitously in states that have legalized and regulated the adult-use market.

During the interview, Volkow also acknowledged that legalization has been associated with “better outcomes” in various states, and that federal laws and regulations on the cannabis plant have “hindered” scientists’ ability to research it – particularly with respect to the plant’s therapeutic efficacy.

Commentary: Herbal Cannabis Vaporization Safer Alternative to Smoking

Toronto, Canada: Vaporizing herbal cannabis reduces consumers’ exposure to combustion-related toxins and provides a safer alternative to marijuana smoking, according to a commentary published in the Canadian Journal of Public Health.

A team of researchers with the University of Toronto’s School of Public Health opined, “Cannabis vaporizer use can reduce the emission of carbon monoxide, chronic respiratory symptoms, and exposure to several toxins while producing similar subjective effects and blood THC concentration compared with smoking cannabis, holding potential for harm reduction among habitual cannabis smokers.”

Vaporizing devices heat cannabis to the point where cannabinoid vapors form, but below the point of combustion. The results of human clinical trials assessing this technology have concluded that vaporizing herbal cannabis is a “safe and effective” cannabinoid delivery mode that does not result in exposure to combustion gases. Researchers have also reported that vaporization results in higher plasma concentrations of THC compared to those associated with smoking cannabis.

Case Report: Cannabis Tincture Associated with Tic Reduction in Tourette Syndrome Patient

Erfurt, Germany: The administration of the proprietary cannabis tincture Nabiximols (a/k/a Sativex) is associated with a “dramatic decrease” in tic-related symptoms in a patient with Tourette Syndrome (TS), according to a case report published in the journal Tremor and Other Hyperkinetic Movements.

A pair of German researchers documented the treatment of a 25-year-old male TS patient with Nabiximols. The patient had previously reported consuming whole-plant cannabis to manage his TS symptoms. Symptoms had returned after he ceased using the plant.

Following at least twice-daily treatment with Nabiximols, the patient experienced a “marked tic reduction … without experiencing relevant side effects.” The acute effects of the drug lasted about four hours.

Authors concluded: “Based on our case, and in line with previous reports, we propose that buccal Nabiximols might be an effective addition to โ€˜acute’ or โ€˜as required’ tic treatment under specialist guidance, especially for predictable situations in the short term when severely disabling or stigmatizing tics are anticipated.”

Sativex is a whole-plant cannabis tincture containing nearly equal ratios of THC and CBD. It is available via prescription in numerous nations, but not in the United States, and it is primarily utilized for the treatment of multiple sclerosis.

Several small studies and case-reports have documented the efficacy of either inhaled cannabis or oral THC in mitigating symptoms in TS patients. In a recent survey of TS patients with experience using either herbal cannabis or oral cannabinoids, those who expressed a preference between the two products said that inhaled cannabis provided superior therapeutic benefits.
