Carefully preserved through smoking practices up to 14,000 years ago, a human body has been found at archaeological sites in Southeast Asia, making it the world’s oldest known mummy.

This custom continues today among the Dani people in West Papua, Indonesia, who mummify their deceased relatives by exposing them to smoke and treat them with care and respect as part of the household. Many of these mummies are found in a tightly bound squatting position.

Similar “highly flexed” ancient remains have also been discovered in Australia, China, the Philippines, Laos, Thailand, Malaysia, South Korea, and Japan.

Hsiao-Chun Hung from the Australian National University in Canberra noted the striking similarities between burial remains excavated in relation to Dani traditions while working on ancient skeletons in Vietnam in 2017.

Hung and her team analyzed the burial practices of 54 hunter-gatherers from 11 archaeological sites across Southeast Asia dated between 12,000 and 4,000 years ago to uncover evidence of smoking. Most sites were based in northern Vietnam and southern China.

Numerous remains displayed clear signs of partial burning, though not enough to indicate cremation. The researchers utilized two analytical methods, X-ray diffraction and infrared spectroscopy, on several bone samples to assess thermal exposure.

Over 90% of the 69 skeletal samples displayed indications of heat exposure. The findings suggest that while human remains were not subjected to extreme temperatures, they likely endured lower temperatures, potentially from smoking for extended periods.

The oldest mummy examined by a Vietnamese team from Hang Cho dates back over 11,000 years. However, a tightly bound skeleton from another site, Hang Mooy, indicates practices recorded over 14,000 years ago. “We didn’t need X-rays or infrared to analyze this one because it’s evidently partially burned and visible to the naked eye,” explains Hung.

Previously, the oldest known mummy was believed to come from northern Chile, approximately 7,000 years ago, and ancient Egypt around 4,500 years ago.

Hung suggests that the evidence indicates this burial tradition likely spread across southern China and Southeast Asia at least 14,000 years ago, as agricultural societies became prevalent in the region around 4,000 to 3,500 years ago. The constricting bindings of mummified bodies may have facilitated their transport, she notes.

Ethnographic studies indicate that these traditions persisted in southern Australia until the late 19th and early 20th centuries, according to Hung. “Additionally, our literature review in the New Guinea highlands reveals that these practices continue among some communities today.”

“Our results signify a unique blend of techniques, traditions, culture, and a profound connection to ancestry that spans an extraordinary timeframe, covering vast regions from the Paleolithic era to the present,” she states.

Vito Hernandez from Flinders University in Adelaide suggests that this study challenges long-standing beliefs that such practices were exclusive to arid regions like Chile’s Atacama and Egypt’s Nile Valley. “It highlights the role of tropical environments in nurturing distinct mortuary traditions among early modern humans across the Far East and potentially into the Pacific,” he remarks.

“By extending the timeline of mummification by at least 5,000 years, the Chinchalo culture [of South America] emphasizes Southeast Asia’s role as a center for cultural innovation, demonstrating a deep continuity that connects early Holocene hunter-gatherers with present-day indigenous groups in New Guinea and Australia,” Hernandez adds.

Smoking Avatars in Online Games: Big Tobacco’s Strategy to Reach Youth in the Metaverse

In the image, a group of friends is gathered at the bar, with smoke curling upwards from a cigarette in hand. Additional cigarettes are in open packets resting on the table between them. This is not a photo from before the ban, but rather one shared on social media from a Metaverse gathering.

Virtual online environments are emerging as a new frontier for marketing, as tobacco and alcohol promoters target the youth without facing any legislative repercussions.

A report presented at the World Conference on Tobacco Management in Dublin last month provided several examples. New technologies such as digital token launches and sponsorships from vaping companies in online games are being utilized to promote smoking and vaping.

This information is derived from a surveillance initiative known as Canary—acting like a canary in the coal mine. The project is managed by public health organizations around the globe.

“Cigarette companies are no longer waiting for regulations to catch up. They are proactively advancing while we’re still trying to comprehend what’s happening on social media, and they’re already operating in unregulated spaces like the Metaverse.” “They utilize NFTs [non-fungible tokens] and immersive events to attract young audiences to their offerings.”

In India, one tobacco company has launched an NFT symbolizing ownership of digital assets, celebrating its 93rd anniversary.

Canary monitors and analyzes tobacco marketing on various social media platforms and news sites in India, Indonesia, and Mexico, and has recently expanded to Brazil and China, covering alcohol and ultra-processed food marketing as well.

The Metaverse is not fully monitored. This 3D immersive internet allows interactions in digital environments using technologies like virtual reality headsets. However, references to activities happening there are captured through links and information shared on traditional social media platforms.

Researchers suggest that children are more susceptible to tobacco marketing in this new digital arena, given the age demographics—over half of the active Metaverse users are under 13 years old.

Social media companies possess extensive insights into how to boost engagement and attract users back for more, according to Dr. Mary-Ann Etiebet, CEO of Vital Strategies.

“When you combine this with the tobacco industry’s experience in hooking individuals, these two elements converge in a murky, unknown space.”

Mark Zuckerberg, a prominent proponent of the Metaverse, has stated that in the future, you’ll be able to do almost anything you can envision. This already encompasses virtual shopping and concerts.

However, Magsambol describes it as “a new battleground for all of us,” shifting towards entities pushing products that are detrimental to health.

“My daughter is usually quite reserved, but in [the gaming platform] Roblox, while battling zombies and ghosts, she morphs into an avatar resembling a blend of Alexander the Great, Bruce Lee, and John Wick. She becomes quite bloodthirsty,” she remarked.

“Our behaviors shift. Social norms evolve… the tobacco industry is highly aware of this, making it easier to subtly promote the idea that anything is possible.”

The Metaverse art encountered by the team in Indonesia was showcased on the Instagram account of music enthusiasts linked to Djarum, one of Indonesia’s largest tobacco firms. Another instance highlighted a group enjoying coffee searching for something lighter.

All of this contributes to an initiative aimed at “normalizing” smoking and vaping, according to Magsambol. “Such behaviors are enacted by your avatar, but do they seep into your real life?”

“Digital platforms are being leveraged to evade traditional advertising barriers and appeal to younger audiences,” she states. “This scenario reflects not merely a shift in marketing strategies, but a transformation in influence dynamics.”

Other researchers have presented instances where alcohol is marketed and sold in virtual stores.

Online marketing constitutes a global concern. At the same conference, 53% of Irish researchers reported having seen e-cigarette posts daily on social media.

Officials from the World Health Organization (WHO) note that the increase in youth smoking in Ukraine can be partially attributed to Covid and the war pushing children “online,” exposing them to various forms of marketing.


In India, youth ambassador Agamloop Kaur is leading a campaign for children to stay cigarette-free, which includes social media marketing to educate school children about the risks associated with cigarettes and vaping. She has noticed vapes being marketed as “wellness” products.

“I believe it’s crucial to educate young individuals about recognizing ads, understanding their implications, and realizing that they might not even be visibly tied to the tobacco industry. [Content posted by] influencers hold significant sway, as they help build awareness. Digital natives, when engaged on social media, can discern what’s genuine and what’s not; recognizing these attractions as empty is vital, especially for younger audiences.”

The WHO Framework Convention on Tobacco Control mandates strict regulations regarding tobacco advertising, promotions, and sponsorships. Last year, signatories acknowledged the necessity for action to focus on “digital marketing channels such as social media that amplify tobacco marketing exposure among adolescents and young individuals.”

Yet, there are no straightforward solutions, as Andrew Black from the framework’s secretariat points out.

“The difficulty in regulating the Internet isn’t inherently linked to cigarettes. Rather, it’s a tangible challenge for governments to devise ways to safeguard societal norms in a landscape where technological advancements have transcended borders.”

The impact of smoking and vaping: it all varies depending on the perspective

Smokers are becoming more hesitant about the benefits of using e-cigarettes to heat nicotine-containing liquids and inhaling vapors, as opposed to inhaling smoke from burning cigarettes.

Research in the UK last year showed that over a third of smokers now believe vaping is more harmful to health than smoking, compared to 12% four years ago, while another third think vaping is just as bad.

Despite scientific evidence showing the harmful effects of smoking and Cochrane reviews suggesting that vaping can help more people quit than other nicotine products, awareness about vaping remains crucial this year as smokers who perceive it as less harmful are more likely to switch.

While both vaping and smoking have known health effects, experts agree that vaping is less harmful than smoking, exposing individuals to fewer toxins at lower levels. This understanding is supported by research conducted by various experts in the field.

Dr. Jamie Hartman Boyce, a health policy expert, emphasizes that while e-cigarettes are not completely safe, they are significantly less deadly than smoking.

Although there are ongoing discussions in the media regarding the harms of vaping, it is important to consider the well-documented risks associated with smoking, which tend to impact older populations.

Health risks

Smoking remains a major risk factor for various health issues, including cancer, heart disease, infertility, and pregnancy complications, resulting in over 8 million deaths annually. Vaping, on the other hand, produces a lesser mixture of toxic substances compared to burning tobacco.

While more research is needed on the long-term effects of vaping, current evidence suggests that it is less harmful than smoking. Dr. Sarah Jackson highlights the importance of acknowledging potential long-term risks while focusing on the existing evidence supporting the relative safety of vaping.

Ongoing research by experts like Dr. Maxime Boidin is aimed at understanding the long-term impact of vaping on health, particularly its effects on blood vessels and the cardiovascular system.

As research progresses, it is crucial to rely on peer-reviewed studies to accurately assess the outcomes and implications of vaping. Media reports on ongoing research can sometimes lead to misconceptions and premature conclusions.

Non-smokers turning to vaping

Evidence suggests that vaping can be an effective method for smoking cessation, with e-cigarettes proving to be more useful than traditional nicotine replacements. However, concerns arise when considering individuals who have never smoked and are now turning to vaping.

It is essential to weigh the risks and benefits of vaping, especially for non-smokers, considering factors like exposure to chemicals and potential nicotine addiction. Choosing between vaping and smoking should be approached with caution, prioritizing health and well-being.

The Victorian Era’s Affinity for Smoking: Uncovering its Effects on Bone Health

Recent archaeological findings indicate that smoking not only stains teeth but also has a literal impact on bones. Additionally, new research suggests that the prevalence of smoking among women in Georgian and Victorian England may have been underestimated compared to men.

In a study conducted by Dr. Sarah Inskip, it was discovered that many women in historical records showed traces of tobacco use, contradicting common beliefs about smoking habits. This finding highlights the importance of considering smoking as a significant health risk for both men and women.


The survey results published in a scientific journal suggest that advancements in analyzing bones for historical information can also aid in modern criminal investigations. By identifying smoking patterns and other lifestyle aspects from bone samples, researchers can create biological profiles to assist in identifying individuals in forensic cases.

Researchers have identified specific molecular markers in bones that indicate smoking habits. By analyzing skeletal remains from different time periods, they found evidence of tobacco use in a significant portion of individuals, including those dating back to the 12th century.

These findings provide valuable insights into the historical prevalence of smoking and its impact on individuals’ health. The research team’s work opens up new possibilities for understanding past health issues and potentially improving modern health outcomes.

Ozempic and Wegovy could potentially aid individuals in smoking cessation

Ozempic has the potential to treat many diseases, not just type 2 diabetes and obesity.

Another study showed that semaglutide (a drug found in Ozempic and Wegovi – It may help treat addiction: Researchers found that people prescribed the drug to treat type 2 diabetes were less likely to seek medical attention for smoking than those taking other diabetes medications.

Semaglutide helps treat obesity and type 2 diabetes by mimicking hormones that suppress appetite and regulate blood sugar levels. Previous studies have also shown that semaglutide reduces the incidence of diabetes. Cannabis Use Disorder and Alcoholism.

To find out the effect of semaglutide on tobacco addiction, Ron Shu Researchers at Case Western Reserve University in Ohio collected data from the electronic medical records of about 223,000 people in the US with type 2 diabetes and smoking habits, about 6,000 of whom had been prescribed semaglutide, and the rest were using one of seven other diabetes medications.

The researchers then tracked whether participants met with a health care provider about smoking or received smoking cessation counseling within a year of starting to take the smoking cessation medication.

After taking into account variables such as age, sex, race and certain health conditions, the team found that people using semaglutide were, on average, less likely to receive tobacco-related medical care than people taking other medications, which the researchers took to be an indication that these people may be more successful in quitting smoking.

For example, semaglutide users were 32% less likely to receive the treatment. Insulin 18% lower than users Metformin user.

People taking semaglutide may be less likely to seek medical care for their smoking, even though they didn’t necessarily stop using such products. But Xu said that because they all sought tobacco-related medical care at similar rates before they started taking type 2 diabetes medication, semaglutide may actually have helped them.

The study was not a randomized controlled trial, which is the highest level of medical evidence, so the results do not conclusively show that semaglutide is behind the effect, he said. Patricia Grigson Kennedy At Pennsylvania State University, however, other studies have shown that semaglutide reduces activity in areas of the brain involved in reward processing and craving, so there may be a causal relationship.

New findings suggest that smoking may lead to an increase in unseen belly fat

When picturing a smoker, the image of a slender and stylish individual like Audrey Hepburn may come to mind. However, recent research indicates that even slim smokers could be harboring unhealthy fat hidden deep within their abdomens.

Despite the common belief that smoking can suppress appetite and the fear of weight gain upon quitting, a new study reveals that smokers are more likely to be underweight. Not only that but smokers also tend to accumulate more harmful deep abdominal fat, known as “visceral fat,” which is linked to increased risks of heart attack, diabetes, and dementia. This type of fat can be challenging to detect, leading to a false sense of fullness even with a flat stomach.


To investigate the relationship between lifelong smoking and belly fat, researchers at the University of Copenhagen utilized a statistical analysis tool called Mendelian randomization. This tool categorizes individuals based on their genetic information to identify causal connections between exposures like smoking and outcomes such as abdominal fat distribution.

The study involved analyzing genetic data from numerous studies on smoking habits and body fat distribution among individuals of European ancestry. By identifying specific genes associated with smoking behaviors and body fat distribution, the researchers were able to determine the impact of smoking on belly fat independent of other influencing factors like alcohol consumption and socio-economic background.

The lead author, Dr. Germán D. Carrasquilla, emphasized the importance of large-scale efforts to prevent and reduce smoking in light of their findings published in the journal Dependence. He believes that reducing smoking prevalence can indirectly decrease the prevalence of abdominal fat and ultimately improve public health outcomes.
