The Impact of Vaping Herbal Cannabis on Lung Health: A Comprehensive Analysis

Vaping is often perceived as the least harmful method to inhale cannabis smoke. However, recent studies challenge this notion, highlighting potential risks associated with vaping, particularly when it comes to lung health. This article delves into the findings from various studies that have explored the effects of vaping on lung health and respiratory systems.

Understanding Vaping and Cannabis Consumption

While vaping cannabis mixed with carrier oils such as MCT oil can increase health risks, pure products without such additives are generally more preferable. It's crucial for vapers to ensure they are using clean, pure products to avoid unnecessary health complications.

Respiratory Health Risks of Vaping

Respiratory health is a primary concern when it comes to vaping, and several studies have shed light on the potential harms it can cause. One notable study, published in the American Journal of Respiratory and Critical Care Medicine in 2017, revealed that e-cigarette usage can trigger harmful immune responses in the lungs, leading to increased levels of NET proteins. These proteins, while vital for fighting pathogens, can also contribute to inflammatory lung diseases such as cystic fibrosis and COPD.

NET Proteins and Lung Health

NETs, or Neutrophil Extracellular Traps, are implicated in cell death within the tissues lining the organs and blood vessels. E-cigarette users exhibited noticeable increases in these proteins in their airways, which is concerning. The study also noted that these users showed a significant increase in NETs outside the lungs, further indicating potential long-term damage.

Furthermore, the study found that vaping can enhance mucus secretions, specifically mucin 5AC, which is linked to lung problems such as asthma and chronic bronchitis. It's important to note, however, that the study included participants who occasionally smoked cigarettes, which may have contributed to the observed effects.

Mimicking the Effects of Traditional Cigarettes

A smaller study published in Toxicology and Applied Pharmacology in 2014 found that vaping and tobacco cigarette smoking had similar short-term effects on the lungs, including lung damage and inflammation. This suggests that vaping, while less harmful than traditional smoking, still poses significant risks.

Flavoring and Lung Health

Flavored e-cigarettes, however, may be even more dangerous. A study conducted by the University of Salford and reported in Science Daily in 2017 tested several flavored e-liquids on lung tissue. The research found that all flavors tested were toxic to the cells, with the worst options including coffee, butterscotch, tobacco, menthol, and bubblegum flavors. The study also revealed that while cells could recover after 48 hours, exposure for 72 hours led to more severe cellular damage.

Genetic Damage and Cancer Risks

Another significant study, conducted by the New York School of Medicine and published in PNAS in 2018, suggested that vaping could damage DNA and increase the risk of cancer. Researchers exposed mice to e-cigarette vapor for three hours a day over five days for 12 weeks. The results showed that the mice exposed to e-cigarette vapor experienced greater DNA mutations, lower DNA repair activity, and lower levels of proteins that bolster DNA repair in cells.

According to the researchers, these findings indicate that e-cigarette smoke is carcinogenic, thus vapers are at a higher risk of lung cancer compared to non-smokers. Additionally, they were more likely to develop heart and bladder cancers. However, it's important to acknowledge the limitations of this study. First, animal studies often do not directly translate to human results. Secondly, the exposure levels used in the study were equivalent to ten years of human vaping in just three months, leading to hyper-exposure effects.

Conclusion

While vaping is generally considered less harmful than traditional smoking, recent studies indicate that it still poses significant risks to lung health and respiratory function. These risks include increased inflammation, genetic damage, and potential carcinogenic effects. It is crucial for vapers to be aware of these risks and to use pure, high-quality products whenever possible. Further research is necessary to fully understand the long-term effects of vaping on lung health and to develop safer alternatives.
