Major cannabis study finds little proof for popular medical claims, flags big dangers
NEWYou can now listen to Fox News articles!
Cannabis has been linked to some significant medical benefits, but recent research calls those into question.
A major new analysis published in JAMA examined more than 2,500 scientific papers from the last 15 years, including other reviews, clinical trials and guidelines focused on medical marijuana.
“While many people turn to cannabis seeking relief, our review highlights significant gaps between public perception and scientific evidence regarding its effectiveness for most medical conditions,” Dr. Michael Hsu of University of California – Los Angeles (UCLA) Health Sciences, author of the study, said in a press release.

The researchers — led by UCLA with contributions from Harvard, UC San Francisco, Washington University School of Medicine and New York University — set out to determine how strong the research is on the effectiveness of medical cannabis and to offer evidence-based clinical guidance.

The review found that evidence supporting most medical uses of cannabis or cannabinoids is limited or insufficient, the release stated.
“Whenever a substance is widely used, there is likely to be a very wide set of outcomes,” Alex Dimitriu, MD, double board-certified in Psychiatry and Sleep Medicine and founder of Menlo Park Psychiatry & Sleep Medicine, told Fox News Digital.
“Cannabis is now used by about 15 to 25% of U.S. adults in the past year, for various reasons ranging from recreational to medicinal. This study points to the reality that this widely used substance is not a panacea,” said Dimitriu, who was not involved in the study.
There are very few conditions for which cannabinoid therapies have clear, well-established benefits backed by high-quality clinical data, according to the researchers.

The strongest evidence supports FDA-approved cannabinoid medications for treating specific conditions, including HIV/AIDS-related appetite loss, chemotherapy-induced nausea and vomiting, and certain severe pediatric seizure disorders.

For many other conditions that are commonly treated with cannabis — such as chronic pain, insomnia, anxiety or post-traumatic stress disorder — evidence from randomized trials did not support meaningful benefit.

The analysis also examined safety concerns — in particular, how young people using high-potency cannabis may be more likely to suffer higher rates of psychotic symptoms and anxiety disorder.
Daily inhaled cannabis use was also linked to increased risks of coronary heart disease, myocardial infarction (heart attack) and stroke when compared with non-daily use.

Based on these findings, the review emphasizes that clinicians should weigh potential benefits against known risks when discussing cannabis with patients.

The authors suggest that clinicians screen patients for cardiovascular risk, evaluate mental health history, check for possible drug interactions and consider conditions where risks may outweigh benefits.

They recommend open, realistic conversations and caution against assuming that cannabis is broadly effective for medical conditions.

“Patients deserve honest conversations about what the science does and doesn’t tell us about medical cannabis,” Hsu said.
This article is a narrative review rather than a systematic review, so it did not use the strict, standardized methods that help reduce bias in how studies are selected and evaluated, the researchers noted.

The review notes further limitations, including that some evidence comes from observational research rather than randomized trials, which means it cannot establish cause and effect.
The trial results also may not apply to all populations, products or doses.

Measles-infected traveler may have exposed passengers at LAX and nearby hotel, health officials warn
NEWYou can now listen to Fox News articles!
A traveler infected with measles may have exposed passengers at Los Angeles International Airport and guests at a nearby hotel after arriving in Los Angeles County earlier this month, health officials said Wednesday.
The Los Angeles County Department of Public Health said it is investigating a confirmed measles case involving a traveler who arrived aboard Cathay Pacific Flight CX 884 on June 11. The traveler was infectious while passing through Los Angeles County, potentially exposing others at LAX and the Hilton Los Angeles Airport Hotel.
The case marks the sixth measles infection reported in Los Angeles County this year. Health officials said the risk of exposure could increase as summer travel ramps up and Los Angeles welcomes international visitors for FIFA World Cup events being held in the region.

According to health officials, anyone who was at the Tom Bradley International Terminal between 10 a.m. and noon on June 11 may have been exposed. Officials also identified a potential exposure at the Hilton Los Angeles Airport Hotel, located at 5711 W. Century Blvd., between 11:15 a.m. and 12:15 p.m. that same day.
The Centers for Disease Control and Prevention is working with local health departments to notify passengers who were seated near the infected traveler on the international flight.
People who were at either location during the listed times could develop symptoms between seven and 21 days after exposure, officials said. The last day to monitor for symptoms is July 2.

“As measles cases increase, it is important that residents take steps to make sure they are fully protected,” Los Angeles County Health Officer Dr. Muntu Davis said. “The MMR vaccine is the safest and most reliable way to prevent measles and protect yourself, your family, and your community.”

As the popularity of GLP-1 drugs continues to climb, significant weight loss associated with the medications has been linked to a growing list of cosmetic concerns.
Some surgeons report that more patients are seeking treatments for so-called “Ozempic earlobes,” which reportedly appear thinner, longer or more sagging after the loss of facial fat.
“The use of semaglutides causes you to lose fat across your body, including the small, fat pads of the earlobes,” facial plastic surgeon Sachin S. Parikh, MD, told NewBeauty.
OZEMPIC, OTHER SEMAGLUTIDES LINKED TO HAIR LOSS: HERE’S WHAT TO KNOW
“It’s important to note that semaglutides do not damage ear tissue or affect hearing in any way, so any intervention would be purely cosmetic,” added the California-based doctor.
Some of the potential treatments for “Ozempic earlobes” may include dermal filler, fat transfer, laser treatments or surgical earlobe reduction, according to the report.

Dr. Mohammed Asif from Duly Health and Care in Naperville, Illinois, said that while he hasn’t personally noticed an uptick in ear surgeries, he has seen a rise in other procedures due to GLP-1-triggered weight loss.
Some of those include panniculectomies (Ozempic skin removal surgery) and abdominoplasties (tummy tucks).

“There has been a significant increase in body contouring procedures among patients with GLP-1 weight loss,” Asif told Fox News Digital.
“In my practice, I’ve seen a significant surge in breast lifts, panniculectomies (skin removal surgery), abdominoplasties (tummy tucks), brachioplasties (arm lifts) and thighplasties due to weight loss.”

Healing and recovery are “far greater and less complicated” than with bariatric surgery weight loss, Asif noted.
“This is due to the gradual weight loss achieved over time with GLP-1s.”
“Ozempic breast” is another common complaint, according to Dr. Michael Omidi, a double board-certified plastic surgeon practicing in Beverly Hills.

“Women in their 30s and 40s would not typically need a breast lift, but when you’re taking drugs like Ozempic or Wegovy that cause rapid weight loss, women can see gravity take its toll on their breasts,” he told Fox News Digital.
“When women, especially younger ones, lose fat too fast, it causes the breasts, which are comprised of fat, glandular tissue and skin, to lose volume,” he went on. “The skin and supporting ligaments don’t always bouce back at the same rate as the weight loss, resulting in breasts that can appear saggy and deflated.”
NEW OBESITY TREATMENT MAY HELP PRESERVE MUSCLE DURING WEIGHT LOSS
Dr. Samuel Golpanian, a double board-certified plastic surgeon in Beverly Hills, said he has seen “dozens” of patients – men and women alike – seeking treatments for so-called “Ozempic butt” after significant weight loss.
“This is an unintended consequence of taking GLP-1s,” he told Fox News Digital.

“Such dramatic weight loss in a short period of time causes the skin not to tighten quickly enough to keep up with the body’s changes. Our buttocks have a large amount of fat, so when that volume disappears quickly, you’ll develop a flatter, saggier behind.”

Kristy Hamilton, MD, a Houston-based surgeon who is a member of the American Society of Plastic Surgeons (ASPS), agreed that a growing number of patients are seeking skin-tightening procedures after losing large amounts of weight with GLP-1s.
“We’re absolutely seeing more of those patients, and I expect that trend to continue,” said Hamilton in an ASPS report.

“People are losing as much as 100 pounds on this medication – and when you’re losing that amount, that’s significant. You’re certainly going to have excess skin afterward.”
The ASPS lists the following body-contouring procedures as the ones most frequently performed after substantial weight loss.

- Tummy tuck (abdominoplasty): Removes excess abdominal skin and fat
- Lower body lift (belt lipectomy): Addresses the abdomen, buttocks, hips and thighs
- Arm lift (brachioplasty): Removes hanging upper-arm skin
- Thigh lift: Tightens excess skin of the inner thighs
- Breast lift (mastopexy): Addresses sagging, deflated breasts after weight loss
- Facelift/neck lift: Addresses facial volume loss and skin laxity after major weight loss

Experts say adequate protein intake and resistance training can help minimize the loss of lean muscle mass that often accompanies rapid weight loss, which could reduce some of the cosmetic concerns.
Golpanian also emphasized the importance of eating enough protein.

“It can be harder since your appetite is suppressed, but it’s so important to consume at least 110 grams of protein a day while taking a GLP-1 drug,” he advised.
“Also, I say this to my patients all the time: You have to lift weights to keep your muscles from atrophying. Strength training can help build muscles and preserve your glutes.”
