One research study identified an abundance of Porphyromonas (a genus of Gram-negative bacteria implicated in periodontal disease) and Veillonella (a different group of Gram-negatives associated with cases of osteomyelitis and endocarditis) in higher levels among vapers, suggesting that vaping alters the oral microbiome. The oral microbiome has an established relationship to overall health and it is the second and most diverse microbiota next to the gut, home to over 1,000 species of microbes.

 

Disruptions to this community can lead to health implications. Of particular concern is the bacterium Porphyromonas gingivalis. Enzymes produced by the bacterium can attack collagen.
 

Periodontal, or gum, disease is one of the most common infectious diseases worldwide. In its more severe forms, such as periodontitis, the condition causes loss of the bone that supports the teeth. In addition to gum disease, the bacterium has been linked to rheumatoid arthritis.

 

Ecosystem stability can be affected by two types of disturbances: long-term influences or “presses” and short-term effects or “pulses”. Furthermore, the researchers discovered that interleukin (IL)-6 and IL-1?, a pro-inflammatory cytokines which indicate inflammatory responses, were highly elevated in e-cigarette users when compared with non-users. In particular, epithelial cell-exposed e-cigarette aerosols were more susceptible for infection. This led to the assessment that e-cigarette users are more prone to infection. This occurs because alterations to the microbial landscape, which accompanies higher levels of proteins in vapers’ mouths, signals that the immune system is more likely to activate and produce inflammation. In turn this exponentially increases the likelihood for disease.

 

Additionally, sequencing based studies have shown that certain species of bacteria (Haemophilus influenzae, Streptococcus pneumoniae, Staphylococcus aureus and Pseudomonas aeruginosa) are more strongly associated with the development of a
lung community skewed towards loss of diversity. Concerningly, these organisms are associated with declining lung function. It appears that e-cigarette vapor can change the way the bacteria grow, by increasing volume and the area covered by the bacteria, which can lead to infections if untreated.
 

The association between the oral cavity and disease is complex, with the pathogenicity of chronic periodontal disease a factor of the complex interaction of microbial pathogens, host immune response, and genetic and environmental factors. The drawing in of chemical vapor adds to the environmental complexity and appears to be a microbiome altering factor. However, what stands out from research is the general trend that the majority of the metagenome in e-cigarette users was shared by more than the majority of users, which contrasts with smokers and non-smokers, who do not tend to share their bacterial and fungal composition.

WHO MOP4 Focuses on Justice and Prosecution to Combat Illicit Tobacco Trade
The Fourth Meeting of the Parties (MOP4) to the Protocol to Eliminate Illicit Trade in Tobacco Products opened in Geneva on November 24, 2025. With 60 Parties participating, the meeting focuses on strengthening legal action and international cooperation to combat illicit trade, which accounts for about 11% of the global tobacco market and costs governments billions in lost tax revenue.

5th Circuit Reviews FDA’s Compliance on Small-Business Impact of Vape Rule
A Fifth Circuit panel expressed doubts about whether the U.S. Food and Drug Administration complied with the Regulatory Flexibility Act when issuing its 2021 final rule on premarket tobacco product applications. Vape companies argued the FDA relied on outdated and inaccurate economic data, while the government said the challenged requirements stem from the Tobacco Control Act.

Illegal tobacco syndicate dominates Australia’s vape market through threats and extortion
Australia’s The Age has revealed that a local tobacco cartel is working with a crime syndicate to dominate the illicit vape trade. The Australian Border Force (ABF) intercepted 115,200 vapes worth A$4.5 million disguised as “furniture” at Sydney port. Authorities say over 12 million illegal vapes have been seized since 2024.
