The EPA Is Funding Research On Using Hemp As A Sustainable Alternative To Concrete

Popular cult classics like The Big Lebowski would have you believe that people who use marijuana not only always have the munchies, but they’re also too lazy to engage in a lot of physical activity.

With those kinds of stereotypes pervading movies and TV shows, it makes sense that many people would assume marijuana use is positively associated with weight gain.

But a new study published last week in the International Journal of Epidemiology appears to undermine that belief. It’s the latest research to show that marijuana users are actually less likely to be obese compared to non-users.

For their work, Michigan State University researchers drew on data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a cross-sectional, nationally representative study sample of U.S. citizens aged 18 and older. In total, they looked at the reported responses of more than 33,000 people.

In the first wave of interviews completed in 2001-2002, participants were asked if they used cannabis and, if so, how recently and how frequently. When they returned for their follow-up interview in 2004-2005, researchers asked participants if they used cannabis since that first interview.

Between the two interview periods, researchers tracked an increase in body mass index (BMI) in all categories of respondents—those who’d never consumed, people who had discontinued past use, “initiates” or newbies and persistent users.

Once they excluded participants who were older than 65 (because research shows BMI declines in older people are often due to loss of muscle mass), they discovered “an attenuated BMI gain for cannabis-use subgroups when compared with never-users.”

In other words, those who reported using marijuana gained weight, but at a reduced rate compared to those who have never consumed cannabis.

“In NESARC, persistent cannabis users and the initiates were under-represented in stably obese subgroups,” the study states. “In addition, these same actively cannabis-using subgroups were under-represented among newly incident cases of obesity observed at W2.”

The study offers a couple of theories to explain why marijuana users experience lower weight gain. One, for example, has to do with how the density of a specific cannabinoid receptor (CB1R) decreases with chronic cannabis use. It’s a theory that was first introduced last year by a separate team of researchers at Indiana University South Bend.

“For many patients,” they wrote in the meta-analysis they published in December, “Cannabis may be a better option for weight loss than surgery or pharmaceuticals.”

Why Marijuana Consumers Have Smaller Waistlines Than Non-Users

Another possibility to explain the relationship between marijuana use and BMI has to do with the anti-inflammatory properties of another cannabinoid receptor, CB2R. “The association of inflammation and obesity is widely established in pre-clinical and clinical studies,” the study’s authors write.

These findings are important for future biomedical research regarding cannabinoids—especially since medical marijuana is often toted as a potential treatment for preventing weight loss in HIV and cancer patients, the study states.

The average cannabis consumer concerned about their waistline might also find a little bit of comfort in these results, too—especially since other research has indicated that states with legal marijuana saw an increase in junk food purchases.

New York City Adds More Exceptions To Pre-Employment Marijuana Testing Ban

An ambitious campaign to decriminalize psychedelics in Washington, D.C., is one step closer to placing their measure on the November ballot with the formal submission of tens of thousands of voter signatures. Organizers have been scrambling for weeks to collect enough signatures from D.C. voters by Monday’s deadline amid historically difficult circumstances: a global pandemic, months of stay-at-home orders and protests over racism and police violence that filled the streets of the nation’s capital. But with the help of innovative signature-gathering techniques and allies flown in from across the country, advocates said they had successfully submitted upwards of 35,000 signatures—more than enough to qualify the initiative. If approved by voters, Initiative 81 would make enforcement of laws against plant- and fungus-based psychedelics among the “lowest law enforcement priorities” for the Metropolitan Police Department. It would not, however, legalize or reduce penalties for the subs

Charlotte Figi The Girl Who Inspired A CBD Movement Has Died At Age 13

Charlotte had recently been hospitalized due to pneumonia, breathing problems and seizures. She was treated as a likely case of Covid-19, her mother, Paige Figi, said Wednesday, although she tested negative for the virus. “Charlotte is no longer suffering. She is seizure-free forever,” a family friend wrote on Paige Figi’s Facebook page, announcing Charlotte’s death. “Thank you so much for all of your love.” Charlotte became a symbol of the possibilities of CBD after CNN Chief Medical Correspondent Dr. Sanjay Gupta told her story in the documentary “Weed.” In the film, Charlotte was shown to be a playful child who was overcome by horrific seizures, which were quelled with Charlotte’s Web, a marijuana strain named in her honor. Charlotte had Dravet syndrome, a rare form of epilepsy which was not controlled by medication. The Stanley brothers, marijuana growers in Colorado, were crossbreeding a strain of marijuana high in CBD and low in THC, its psychoactive ingredient. After Charlo

Virginia CBD Program Criticized As Multistate Medical Cannabis Operators Gain Edge

Seven companies are challenging a CBD licensing process in Virginia that resulted in multistate medical marijuana operators getting a majority of available licenses. The appeals called the process “wildly prejudicial.” Out of 51 applicants for five vertically integrated CBD and THC-A licenses, multistate operators received three, a situation that spurred the appeals, The Virginian-Pilot reported. Applicants filing the appeals complained the closed-meeting review process lacked fairness and transparency. One consultant to an applicant said the selections felt “predetermined.” The Virginia Board of Pharmacy reportedly sent information to the applicants in December explaining its selections, but some applicants weren’t satisfied. A board spokeswoman wrote in an email to the Pilot that the board “does not comment on pending litigation.” The five winning applicants , called “pharmaceutical processors,” have a year from winning the licenses to become operational. The multistate
