Disposable vapes more toxic and carcinogenic than cigarettes, study shows

Illegal disposable e-cigarettes, also known as vapes, may present a greater danger than traditional cigarettes, according to a study from the University of California (UC) Davis.

The research, published in the journal ACS Central Science, found that hazardous levels of several toxic heavy metals in illegal vapes could present a high cancer risk.

Researchers used a special instrument to test the puffs from three popular vape brands — ELF Bar, Flum Pebble and Esco — that are not FDA-authorized for use in the U.S., but are widely sold by retailers.

Three heavy metals — lead, nickel and antimony — were detected in all heavily flavored and lightly flavored devices that were tested. 

These metals are classified as carcinogens, potentially leading to various types of cancers, such as skin, lung and kidney, according to the National Institutes of Health (NIH).

All vapors exceeded the cancer risk limits for nickel, which has been linked to cardiovascular disease, asthma, lung fibrosis and respiratory tract cancer, per NIH.

Brett Poulin, senior study author and assistant professor at the UC Davis Department of Environmental Toxicology, told Fox News Digital that he was shocked at the levels of toxic metals.

“When I analyzed the first samples, the lead concentrations were so high that I genuinely thought the instrument was broken,” he said. “The levels far exceeded anything in our past data, or even the published literature.”

One of the brands tested exposes users to as much lead as smoking 19 packs of cigarettes, the researchers discovered.

Additionally, most of the disposable e-cigarettes tested in the study were found to contain greater levels of metals and metalloids than older refillable vapes.

At one point, Poulin said, he physically opened a device and discovered that it was using leaded copper alloys, which are metals made primarily of copper with small amounts of lead.

“These materials leached dangerous levels of lead into the e-liquid, even without the device being used,” Poulin told Fox News Digital.

“It remains unclear whether this was an intentional design choice, a cost-cutting measure or a manufacturing oversight.”

“This neurotoxin poses serious health risks, particularly to children and adolescents.”

There is no known safe level of lead exposure, according to Poulin.

“This neurotoxin poses serious health risks, particularly to children and adolescents, who are especially vulnerable.”

Daniel Sterman, M.D., director of the Pulmonary Oncology Program at the NYU Langone Perlmutter Cancer Center, told Fox News Digital that the study “clearly” demonstrates high concentrations of metal.

“There are several health risks of vaping that we enumerate for our patients and their family members, [such as] risks of various lung diseases, including asthma, COPD and lung cancer,” said Sterman, who was not involved in the study.

The doctor noted that while it is challenging to establish a direct link of causation between disposable vapes and cancer, he does see cancer patients who use the devices.

“Disposable vapes should be highly regulated by local, state and federal agencies, and restricted to those individuals 21 years or older,” Sterman recommends.

The doctor also called for the packaging on disposable vapes to clearly outline the many health risks, “particularly to teenagers and young adults.”

Potential limitations

One of the primary limitations of the study was that only three disposable e-cigarette brands were tested out of the hundreds currently on the market. 

There are distinct differences in the metal leaching and profiles across all three brands, Poulin shared.

The Center for Disease Control (CDC) found that the percentage of adults who used electronic cigarettes increased from 4.5% in 2019 to 6.5% in 2023. (iStock)

“We still know very little about the metal content in the vast majority of untested disposable e-cigarette products,” he said. “This gap in knowledge poses a significant public health concern, especially given the popularity of these devices.”

A spokesperson for the China-based brand, ELFBAR, told Fox News Digital that they refute the results of the study, claiming that they stopped shipments in May 2023.

Due to ongoing trademark litigation, they are unable to market or sell products in the U.S., the company stated.

“This market void has led to a surge in counterfeits, imitations and illicit variations misusing our brand name,” the spokesperson said. “As such, we have every reason to believe the devices tested in this study are not genuine and were not manufactured by ELFBAR.”

The spokesperson acknowledged that smoking remains the leading cause of preventable death and disease worldwide, noting that the recent study “continues to undermine public understanding of smoking cessation.”

The other two brands tested in the study did not respond to requests for comment.

“Disposable vapes should be highly regulated by local, state and federal agencies and restricted to those individuals 21 years or older.”

Electronic cigarette use among adults increased from 4.5% in 2019 to 6.5% in 2023, according to the U.S. Centers for Disease Control and Prevention (CDC).

Men are more likely to vape than women, while 15.5% of young adults between the ages of 21 and 24 reported using e-cigarettes, the above source states.

Detransitioner Chloe Cole shares complications after gender procedures: ‘I am grieving’

Detransitioner Chloe Cole shares complications after gender procedures: ‘I am grieving’

NEWYou can now listen to Fox News articles!

Medical victim Chloe Cole was at the center of the U.S. Department of Health and Human Services’ Thursday announcement of proposed regulatory actions to end “sex-rejecting procedures” on minors.

The proposed regulatory actions by the HHS are part of President Donald Trump‘s January executive order calling on the department to protect children from “chemical and surgical mutilation.”

The department is rolling out a series of policy updates and regulatory actions that would effectively defund hospitals that provide gender transition procedures, according to an HHS official. 

NUMBER OF YOUNG ADULTS IDENTIFYING AS TRANSGENDER PLUNGES BY NEARLY HALF IN TWO YEARS

Cole, now 21 years old, went through the process of medical transition from female to male between the ages of 12 and 16.

The California native took to the stage alongside HHS Secretary Robert F. Kennedy Jr. and other officials Thursday to advocate for the protection of children. Afterward, she told Fox News Digital the puberty blockers, testosterone injections and double mastectomy she endured have irreversibly and permanently affected her health.

“As soon as gender was in the picture, none of my doctors or psychologists asked the real questions that they should have,” said Cole. “The entire focus was on my feelings and what I wanted rather than what I really needed in that moment.”

What she needed, Cole said, was to be loved and affirmed for the way God created her — “as a young and yet tomboyish little girl.”

She maintained that her doctors neglected to share risks, only touting the “benefits” of stopping female puberty and using testosterone to promote body hair growth, musculature and different fat distribution.

“There was nothing they could say to me that would make me understand the gravity of what I was about to go through, because I was still growing up,” said Cole. “I had very little experience in the world, and I simply would not be mature enough to be equipped to undergo such a life-changing procedure in every way.”

Cole noted that her parents never thought she was transgender, but felt like the odds were stacked against them.

“At the time when we started going through this as a family, there really were no resources that would speak to the reality of transgenderism, especially for children,” she said. “Most people were not aware then that this was something that was even happening in our hospital systems.”

Cole said her parents were warned that if they did not allow her to transition, she would likely commit suicide. 

“My legal guardians were forced to make this decision under duress,” she shared in a previous statement. “But even if my parents had supported transitioning medically from the start, no parent or any adult, ultimately, has a right to determine whether a child gets to be chemically sterilized or mutilated.”

“While there are only two sexes, there’s a million different ways that you can be yourself,” said Cole, pictured above during her surgeries.  (Chloe Cole)

Cole said she’s suffered numerous complications from her medications and surgery. “My quality of life is still being impacted to this day,” she wrote in her statement.

Her fertility status now remains unknown, she said. She will not be able to breastfeed because her breasts were surgically removed.

“As an adult, I am now grieving, and on top of that, the areolar skin grafts they used in my surgery began to fail two years afterward. I must wear bandages on my chest every day,” Cole wrote. 

“As an adult, I am now grieving.”

In 2023, Cole filed a lawsuit with the Center for American Liberty (CAL) against hospitals for pushing her into what she believes is medical mutilation.

Mark Trammell of CAL told Fox News Digital that Thursday’s HHS announcement “represents a critical acknowledgment that experimental medical interventions on children with gender distress have failed to meet basic standards of safety and effectiveness.”

Cole, who detransitioned after medical procedures, is warning others to wait and seek family support before transitioning. (Fox News Digital)

“It signals that medicine must return to its core ethical obligation: First, do no harm,” Trammell added. 

“We will continue fighting to ensure accountability for the institutions that promoted these practices and to secure justice for the children and detransitioners whose lives were forever altered.”

In a previous statement provided to Fox News Digital, Dr. Marc Siegel, Fox News senior medical analyst, said he is in favor of a “more conservative approach” for minors.

“Long-term effects of puberty blockers may include bone loss, trouble concentrating, interference with learning and interference with fertility,” he said. “I think it makes sense in most cases to treat underlying mental health concerns before jumping into treatments, including surgery, that may be difficult to reverse.”

“It makes sense in most cases to treat underlying mental health concerns before jumping into treatments.”

The doctor also emphasized that gender issues should not be overly politicized. “This means not superimposing an ideology or pushing physicians to act in a certain way or under pressure,” Siegel said.

“The welfare of the child must come first. In this case, it means going very slowly and providing support to a child or teen with gender dysphoria.”

Cole shared that she hopes any children who are questioning whether they should transition wait.

While there are only two sexes, there are a million different ways that you can be yourself,” she added.

“God is there for you. He is the one who has created you this way, and you can seek his counsel,” Cole went on.

“You can continue praying, and I think ultimately it’s connecting with your family, building your purpose in this world, and looking to the gospel and up to God.”

Simple lifestyle changes could slash heart attack risk for millions, scientists report

Simple lifestyle changes could slash heart attack risk for millions, scientists report

NEWYou can now listen to Fox News articles!

Those at risk of type 2 diabetes may be able to prevent heart problems later.

A new study published in The Lancet Diabetes & Endocrinology discovered that lowering the blood sugar of those with prediabetes could reduce the risk of heart attack by half.

Diabetes researchers and endocrine experts across Europe, China and the U.S. investigated how bringing blood sugar back to normal levels affected the chances of heart problems later in life, based on a 20-year American study and a 30-year Chinese study, according to a press release.

In both studies, the prediabetic participants were coached to make appropriate lifestyle changes to lower blood sugar (the amount of glucose in the bloodstream) through diet and exercise, also targeting weight loss.

The researchers split the participants into a remission group (where blood sugar returned to normal) and a non-remission group, which included those still in the prediabetes range. They then determined who in these groups had died from heart disease or were hospitalized for heart failure.

Participants who went into remission had a 58% lower risk of dying from heart disease and being hospitalized for heart failure. This group also had a lower risk of other major heart events and lower overall death rates.

These heart-protective benefits lasted for decades after the program ended, the researchers found.

“Reaching prediabetes remission is linked to a decades-long benefit, halving the risk of cardiovascular death or hospitalization for heart failure in diverse populations,” the researchers commented in the publication of the study. “Targeting remission might represent a new approach to cardiovascular prevention.”

In an interview with Fox News Digital, Dr. Andreas Birkenfeld, study co-author and professor of medicine at the University Hospital Tübingen in Germany, reiterated that reaching prediabetes remission is not only relevant for reducing the progression of type 2 diabetes, but may also be associated with a “meaningful reduction in… heart attack risk, cardiac death and heart failure.”

“Importantly, this underscores that prediabetes is a modifiable stage where timely, evidence-based interventions (especially lifestyle measures, and in selected cases, medication) can make a real difference,” he added.

The study did have some limitations, including that it is based on analysis of trials not originally designed to measure cardiovascular outcomes, which means the results show association but cannot prove causation.

In addition, unmeasured lifestyle and health factors, population differences and lack of randomization for heart outcomes may have influenced the reduced cardiovascular risk, the researchers acknowledged.

“This underscores that prediabetes is a modifiable stage where timely, evidence-based interventions … can make a real difference.”

Birkenfeld suggested that those with prediabetes should ask their doctors the following questions: “What is my current status? What is my personal cardiovascular risk? What is my target blood glucose level?”

Patients should also inquire about the frequency of testing for blood sugar and key risk factors like blood pressure, cholesterol and other related conditions, such as kidney function or sleep apnea, he advised.

“If lifestyle changes aren’t enough or my risk is high, would medication be appropriate for me — and what are the benefits and downsides?” the researcher asked as an example.

About 98 million American adults, more than one in three, have prediabetes, according to CDC data. Eight in 10 of these adults are unaware that they have the disease.
