Sleep and Medicinal Cannabis

INVESTIGATOR: Sean Drummond, Ph.D.

STUDY LOCATION: University of California, San Diego

PROJECT TITLE: Sleep and Medicinal Cannabis

PROJECT TYPE: Clinical Study, Sub-Study

STATUS: COMPLETE

ABSTRACT:

Recently, there has been renewed scientific interest in examining the medical efficacy of cannabis in specific patient populations. For, example, both the Institute of Medicine and the NIH recently reported medicinal cannabis might be useful in the treatment of pain in HIV+ patients. HIV+ patients experience a number of clinical sequelae to the infection, even when they are otherwise considered clinically "asymptomatic." Perhaps one of the earliest sequelae is sleep abnormality. It is estimated that 73% to 90% of HIV+ patients experience significantly disrupted sleep and sleep quality has been shown to predict long-term outcome in HIV+ patients. This study examines the effects of daytime medicinal cannabis administration on subsequent nocturnal subjective and objective measures of sleep in patients with HIV-associated DSPN. We will recruit 15 patients who are enrolled in a study currently funded by the CMCR (PI: Dr. Ellis; Award # C00-SD-104). Dr. Ellis' study examines the efficacy of medicinal cannabis vs. placebo in treating pain in patients with HIV-associated DSPN. Here, subjective sleep will be measured for three 1-week periods: a wash-in week, a week of cannabis administration, and a week of placebo administration. Objective sleep will be studied for two consecutive nights under both cannabis administration and placebo conditions. We hypothesize that, compared to placebo, cannabis will increase slow wave sleep and sleep efficiency and decrease REM sleep. Subjectively, patients will report increased global sleep quality, decreased sleep latency, and increased total sleep time with cannabis administration. If these hypotheses are borne out, it will provide evidence that cannabis has positive medicinal qualities beyond those formally suggested. Improved sleep may directly affect prognosis in these patients and may have several indirect benefits as well. Regardless, this study should provide pilot data for subsequent grant applications focusing on the direct effects of medicinal cannabis on sleep in patient populations.

Funding Opportunity Announcement

The Center for Medicinal Cannabis Research (CMCR) is seeking to fund primary and pilot cannabis-related studies that further enhance the understanding of the efficacy and adverse effects of cannabis and cannabinoids as pharmacological agents for the treatment of medical and psychiatric disorders, and their potential public health impacts. More information about this funding opportunity, including application instructions and important dates can be found in the request for applications (RFA).


Marijuana research still shackled by Feds three years after DEA promised to lift monopoly

Brooke Staggs, Orange County Register, May 8, 2019

Nearly three years after the Drug Enforcement Agency announced it would end a monopoly on who can grow cannabis for legally sanctioned research, there’s still only one federally authorized cannabis cultivator in the United States.

And the limited supply of research cannabis is hampering the speed, quality and range of studies that scientists can conduct on the potential medical benefits, or harms, of marijuana — even as demand for reliable cannabis research soars.

“It is politics and not science that is interrupting the conduct of this research,” said John Hudak, a fellow at the nonprofit Brookings Institution who specializes in marijuana policy. “And that is not something that Americans should stand for.”

Harvard, MIT share $9 million gift to study marijuana’s health effects

Felice J. Freyer, Boston Globe, April 30, 2019

An investor in the cannabis industry has donated $9 million to Harvard and MIT to study the drug’s health effects, in what the institutions describe as the largest private gift to support marijuana research in the United States.

The Broderick Fund for Phytocannabinoid Research, announced Tuesday morning, will be shared equally by Harvard Medical School and the Massachusetts Institute of Technology, with the goal of filling vast gaps in the understanding of how marijuana affects the brain and behavior.

“The lack of basic science research enables people to make claims in a vacuum that are either anecdotal or based on old science,” said the donor, Charles R. “Bob” Broderick, an alumnus of both universities. “For generations we haven’t been able to study this thing for various sorts of societal reasons. That should end now, as well as the prohibitions that are falling around the world.”

What to Know About the CBD at Your CVS

Marty Munson, Men's Health, April 3, 2019

CVS and Walgreens announced they’re going to sell products containing CBD, best known as the component of marijuana that won’t make you high, in certain stores. CVS is currently selling CBD topicals—creams, sprays, and lotions—in eight states. Walgreens announced its intention to sell CBD products days later, but “isn’t sharing additional details at this time,” according to a spokesperson.

If CBD hadn’t already reached fever pitch, with products like CBD-containing gummies, beer, coffee, eye creams, and even (no kidding) suppositories flooding the market, this announcement legitimizes the compound further.

But market share and the veneer of legitimacy doesn’t mean there’s a lot of clarity around the stuff. Here’s what to know about CBD before you buy:

No, CBD-infused jelly beans won’t get you high. Here’s why.

Eli Rosenberg, Washington Post, March 19, 2019

There is CBD beer, and CBD coffee, and CBD gummies and soda, skin care, oils and drops. And now the cannabis-derived product is appearing in jelly beans — designed by the man who created Jelly Belly candies.

The product, a mash-up of an “adult” chemical compound — CBD — and a staple of American childhoods, has been so popular that the company that created it, Spectrum Confections, helmed by Jelly Belly inventor David Klein, sold out after a spate of press coverage over the past week.

“Jelly Belly creator debuts cannabis-infused jelly beans: Toasted marshmallow, mango and more,” USA Today wrote.
