Pot Smokers May Have Lower Risk of Obesity

“Despite the tendency of marijuana users to experience the “munchies,” pot smokers may have a lower risk of obesity that those who don’t use the drug, a new study finds.

The results show the prevalence of obesity is lower among people who frequently smoke pot compared with those who have never inhaled.

The researchers said they were surprised by their initial results, because they expected to find the opposite. So they examined a second sample of people, and found exactly the same result. Together, the two samples studied more than 50,000 people.

The reason behind the link is not clear. It could be that people who use cannabis also engage in other behaviors that lower their obesity risk. Or it may be that pot smokers exercise more or have a specific diet that keeps them thin, said study researcher Yann Le Strat, a psychiatrist at Louis Mourier Hospital in France.

“On a personal point of view, I would be surprised that cannabis use is associated with a higher rate of physical activity, but this cannot be ruled out,” Le Strat told MyHealthNewsDaily.

Another possibility is that components of cannabis may help people lose weight. If this turns out to be the case, researchers should investigate which components these might be and try to put them into drug form, Le Strat said.”

“”Initially, we thought we made a mistake,” said Le Strat, adding that he and co-author Bernard Le Foll checked the results several times to make sure they were correct.

“This is only a preliminary result. It doesn’t mean that marijuana does actually help you lose weight, but perhaps there is a component that does.”

The study, published in the American Journal of Epidemiology, included two surveys of U.S. adults — one covering 43,000 people, the other about 9,300 respondents. Both had been conducted by branches of the U.S. National Institutes of Health between 2001 and 2009.

The larger of the surveys found that 14 percent of pot smokers were obese compared to 22 percent who didn’t smoke pot. Similarly, the smaller survey found 17 percent of pot smokers to be obese compared to 25 percent of non-smokers.”

“If cannabis causes the munchies, how is it possible that pot smokers are thinner than nonsmokers?

A new study published in the American Journal of Epidemiology finds an intriguing connection between marijuana use and body weight, showing that rates of obesity are lower by roughly a third in people who smoke pot at least three times a week, compared with those who don’t use marijuana at all.

Researchers analyzed data from two large national surveys of the American population, which together included some 52,000 participants. In the first survey, they found that 22% of those who did not smoke marijuana were obese, compared with just 14% of the regular marijuana smokers. The second survey found that 25% of nonsmokers were obese, compared with 17% of regular cannabis users.”

How marijuana could help cure obesity-related diseases

“According to a new British study, marijuana leaves (not the buds that Willie Nelson loves so dearly) contain two compounds that boost the metabolism of mice, leading to lower levels of fat and cholesterol in the body — the latest addition to a growing body of evidence that marijuana may be useful in countering ailments related to obesity. One study in March found that a brain chemical similar in structure to an active compound in cannibis could help people shed weight, while another study last September concluded that pot smokers were less likely to be obese than non-potheads, though for reasons that remain unclear.   

The two compounds, THCV and cannabidiol, boosted the rodents’ metabolisms — reducing fat levels in their livers and cholesterol levels in their bloodstreams — and also made the mice more sensitive to insulin and protected the cells that produce insulin, “allowing [the cells] to work better and for longer.” The combined effects improved the mice’s ability to burn off energy.

And the compounds didn’t make mice hungry the way smoking weed affects humans?
Actually, the compounds were found to have an appetite-suppressing effect, but the effect only lasted for a short time.”

Cannabis drug could help fight obesity

“Apparently scientists have discovered that a natural component of cannabis suppresses the appetite and that discovery may lead to a new class of drugs for treating obesity.

Scientist professor Roger Pertwee, a neuropharmacologist at Aberdeen University, says it was already well known that cannabis stimulated the appetite, but not widely known that the plant also contained substances that produced the opposite effect.

That substance is apparently called THCV and is chemically similar to another cannabis chemical, or cannabinoid, called THC that stimulates the appetite.

As drugs based on THC are already being used to increase the appetite of AIDS patients, the focus is now on developing THCV for use as an anti-obesity drug, said Professor Pertwee.

Pertwee says that cannabis is rich in substances that can mimic the natural or endogenous cannabinoids in the brain, that act as chemical messengers in the nervous pathways, involved in such activities as appetite control or pain relief.

These endogenous cannabinoids seem to act on the reward pathways to the brain, to increase the reward you get when you take food, but can have harmful effects.

By increasing appetite they can increase fat, which can give rise to obesity or overweight.

Drugs are apparently now being developed that can increase the levels of these chemicals in our brains by slowing down the rate at which they disappear once they have been released,says Pertwee.

Professor Pertwee has also found a method of potentially boosting the signals in the brain that are generated by these endogenous cannabinoids.”

Cannabis can help treat obesity

“Two cannabis compounds can raise the quantum of energy the body burns and keep obesity at bay. Called THCV and cannabidiol, they were found to have an appetite suppressing effect too for a short while.

Animal tests have shown these compounds can help treat type two diabetes while also lowering levels of cholesterol in the blood stream and fat in key organs like the liver.

Scientists also found the compounds also had an impact on the level of fat and its response to insulin, a hormone that controls blood sugar levels, the Telegraph reports.

THCV was also found to increase the animals’ sensitivity to insulin while also protecting the cells that produce insulin, allowing them to work better and for longer.

Steph Wright, director of research and development at GW Pharmaceuticals developing the drugs, said: “The results in animal models have been very encouraging. We are interested in how these drugs effect the fat distribution and utilisation in the body as a treatment for metabolic diseases”.”

‘Cannabis’ receptor discovery may help understanding of obesity and pain

“Aberdeen scientists believe that the findings—published in the —might help our understanding of these conditions and also be a step towards the development of personalised therapies to help treat them.

The team from the University’s Kosterlitz Centre for Therapeutics studied around the gene CNR1. This gene produces what are known as cannabinoid receptors, which are found in the brain, and which activate parts of the brain involved in memory, mood, appetite and pain.

activate these areas of the brain when they are triggered by chemicals produced naturally in our bodies called .

Chemicals found in the drug cannabis mimic the action of these endocannabinoids and there is growing evidence that cannabis has pain relieving and anti-inflammatory properties which can help treat diseases such as and arthritis. 

In order to understand more about these side effects and the which determine how people respond, the scientists studied genetic differences around the CNR1 gene.

Dr Alasdair MacKenzie, who helped lead the team, said: “We chose to look at one specific genetic difference in CNR1 because we know it is linked to and addiction. What we found was a mutation that caused a change in the genetic switch for the gene itself—a switch that is very ancient and has remained relatively unchanged in overthree hundred million years of evolution, since before the time of the dinosaurs.”

Marijuana May Deflect Obesity

“Cannabis seems to have many different allures. It can produce a “high.” It can give the feeling of munchies. Now, it can possibly help combat obesity. Scientists recently revealed that they found two compounds from cannabis leaves that could up the total energy that the body burns.

Previous studies of two specific compounds demonstrated that they could be used to treat type-two diabetes. The compounds were also discovered to have the ability to reduce cholesterol levels in the blood stream and decrease fat in important organs such as the liver. With the aim of treating patients who have “metabolic syndrome,” the researchers are currently conducting clinical trials in 200 patients with the drug. With “metabolic syndrome,” diabetes, high blood pressure, and obesity combine to heighten the risk of heart disease and stroke in patients.

“We are conducting four Phase 2a clinical trials and we expect some results later this year,” commented Dr. Steph Wright, director of research and development at GW Pharmaceuticals, in a Telegraph article. “The results in animal models have been very encouraging. We are interested in how these drugs effect the fat distribution and utilization in the body as a treatment for metabolic diseases… Humans have been using these plants for thousands of years so we have quite a lot of experience of the chemicals in the plants.”

GW Pharmaceuticals was given a license to grow cannabis in greenhouses that were specially constructed for project. The company produces cannabis plants that have a number of cannabinoids, which are varied compounds of cannabis. They are already working on creating drugs that can assist in treating epilepsy and multiple sclerosis. Interesting enough, when the scientists studied two specific compounds, THCV and cannabioidol, they found that they had the ability to suppress appetite but the effect lasted for a short amount of time. Upon further examination, the investigators discovered that the compounds could influence the fat level in the body as well as its effects to the hormone insulin.

Likewise, the studies of the compounds in mice showed that they increased the metabolism of the animals, causing decreased levels of fat in livers and minimized levels of cholesterol in the blood stream. In particular, THCV showed the ability of boosting the animals’ sensitivity to insulin but also shielding the insulin-producing cells. With these actions, the cells were able to work at a longer and more durable pace.

The researchers hope that the findings will help in the development of treatments for obesity-related illnesses and type-two diabetes.”

Fight obesity… with marijuana?

“What did the study find?
Dr. Yann Le Strat, a psychiatrist at France’s Louis-Mourier Hospital, looked at data from two studies of U.S. adults from the early 2000s and noted the weight differences between those who used cannabis and those who didn’t. In both studies, cannabis users had relatively low rates of obesity: 14.3 and 17.2 percent. American adults who didn’t use cannabis had obesity rates of 22 and 25.3 percent.

Is this what researchers expected?
Nope. “Cannabis is supposed to increase appetite,” says Le Strat. “So we hypothesized that cannabis users would be more likely to have higher weight than non-users and be more likely to be obese.” Marijuana activist Michelle Aldrich isn’t all that surprised. “It’s true,” she says. “I don’t know too many fat marijuana smokers.”

What’s causing this phenomenon?
“There could be many other reasons why pot smokers have less obesity,” says dietitian Andrea Giancoli. “Maybe they’re inclined to exercise more, be outdoors more, eat more fruits and vegetables.” Aldrich thinks it could be related to the body’s endocannabinoid system — a group of receptors, primarily in the brain, that respond to compounds in marijuana. But the bottom line is that the exact mechanism responsible for this correlation remains a mystery — for now.”
