Marijuana Consumers Gain Less Weight Than Non-Users, Study Confirms

Published

on

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.

Dogs Treated With Cannabis Oil Experience Less Frequent Seizures, Study Finds

Published

on

Dogs with epilepsy experience considerably fewer seizures when treated with CBD oil, a new study published in the journal Pet Behaviour Science found.

The small study—which followed three dogs receiving hemp-derived CBD treatment over the course of two months, indicates that dogs respond to the cannabis compound in a way that’s similar to humans.

The dogs ranged in age and breed. One was a three-year-old Labrador Retriever that suffered seizures spaced out one month apart on average, another was an 11-year-old Papillon that experienced seizures every two to three months and the last was a 10-year-old Chihuahua that has infrequent seizures about twice a year.

For the experiment, each dog was treated with CBD twice a day on an empty stomach. The findings are based on reports from the owners, two out of three of whom said the treatment improved their dog’s condition. The Papillon’s owner said the dog’s condition was unchanged.

“The owner [of the Labrador Retriever] reported that the dog slept longer and barked less in the daytime, even when other dogs were excited, during the first two weeks than in the preceding weeks,” the study authors wrote. “Overall, the owner felt that the dog showed improvement.”

“The owner [of the Chihuahua] felt that seizure-like behavior during the attacks had decreased slightly with treatment,” they wrote. “The owner also reported that the dog showed less aggression toward familiar people, such as the owner’s children.”

While the sample size of the study is particularly small, making it difficult to draw broad conclusions, the researchers said “seizure frequency improved considerably and owners reported a positive impression” of the CBD treatment.

It’s not clear if the same biochemical mechanisms that make CBD an effective treatment for epilepsy in humans produced the effects in the dogs. It’s possible that, because seizures can be triggered by anxiety, the same “anxiolytic effect may attenuate the symptoms of epilepsy in dogs as well as humans.”

“Further research is needed for better understanding the neurobiological mechanisms of CBD treatment,” the researchers wrote.

Last year, a separate study determined that CBD can alleviate the symptoms of osteoarthritis in dogs.

Study Finds Marijuana Motivates People To Exercise, Smashing Lazy Stoner Stereotype

Published

on

Most people who use marijuana report that consuming before or after exercising improves the experience and aids in recovery, according to a new study. And those who do use cannabis to elevate their workout tend to get a healthier amount of exercise.

Researchers at the University of Colorado surveyed more than 600 marijuana consumers in states where it is legal to assess how people use cannabis in relation to exercise. Their results, published this month in the journal Frontiers in Public Health, poke yet another hole in the lazy, couch-locked stoner stereotype.

Almost 500 participants said they endorse using marijuana one hour before, or up to four hours after, exercising. And based on data from the questionnaire, those who did use cannabis in that timeframe worked out longer than consumers who didn’t pair the activities. Specifically, those who engaged in co-use worked out an average of 43 minutes longer for aerobic exercise and 30 minutes longer for anaerobic exercise.

What’s behind the trend?

There are a few known barriers to exercise that researchers have identified: a lack of motivation, difficult recovery after working out and low enjoyment of the activity. Cannabis seems to help lift those barriers for some individuals.

Seventy percent of respondents said they agree or strongly agree that “cannabis increases enjoyment of exercise,” 78 percent said that marijuana “enhances recovery from exercise” and just over 50 percent said that it “increases motivation.”

“To our knowledge, this is the first study to survey attitudes and behavior regarding the use of cannabis before and after exercise, and to examine differences between cannabis users who engage in co-use, compared to those who do not,” the study authors wrote. “Given both the spreading legalization of cannabis and the low rates of physical activity in the US, it behooves public health officials to understand the potential effects—both beneficial and harmful—of cannabis use on exercise behaviors.”

While it might seem counterintuitive given how cannabis consumers have typically been portrayed in media, there’s a growing body of research showing that many marijuana enthusiasts engage in active lifestyles and that cannabis is associated with positive health outcomes. For example, another recent study found that people who use marijuana are less likely to be obese compared to non-users.

Another Federal Agency Wants You To Stop Calling About A Marijuana-Related Job

Published

on

Six days after posting a notice that calls for a contractor to prepare and distribute research drug products like marijuana cigarettes, a federal agency posted an update, emphasizing that private citizens are not being encouraged to apply for a casual joint-rolling job.

Why? Well, it might have something to do with various viral articles reporting on the opening—and readers who then volunteer for the role.

On Monday, the National Institute on Drug Abuse (NIDA) added an unambiguous message at the top of the notice: “THE FOLLOWING IS A PRE-SOLICITATION NOTICE and is NOT ADVERTISEMENT FOR EMPLOYMENT.

The situation seems similar to another recent example that prompted the Houston division of the Drug Enforcement Administration (DEA) to ask private citizens to stop calling about a contractor opening to incinerate thousands of pounds of cannabis per hour.

The division wrote last month that “misleading articles” about the position “resulted in an influx of calls from citizens.”

“This solicitation was targeted for a large scale licensed vendor, not private citizens,” they wrote.

But according to NIDA, their problem isn’t quite as severe. In an email to Marijuana Moment, a representative of the agency said it has “only received a few public inquiries.” The spokesperson did not respond to a follow up question about the reasoning behind the update.

For serious candidates, the position isn’t as simple as rolling a massive amount of joints. The contractor must have “the capability to analyze and characterize various drugs of abuse including cannabinoids and other research chemicals” and also “acquire, develop, and produce marijuana and nicotine research cigarettes of varying strengths and specifications.”

NIDA posted several cannabis-related contract notices last year, including for professional joint rollers and bulk marijuana manufacturers.
