WARNING

In recent years, the topic of the dangers of e-cigarettes and smoking and health has continued to generate heated debate. As the market for vape expands, vapors are often confused as to which is less harmful. This blog analyzes the potential risks of these two types of inhaled products through a scientific lens.

I. Ingredient Mist: Invisible Chemical Threats
Traditional cigarettes burning tar carcinogens have been widely known, while e-cigarettes release aerosols by heating the vape juice. Research at Johns Hopkins University found that some vape juice contain propylene glycol and formaldehyde releasers, which may be converted into respiratory irritants at high temperatures. It is worth noting that the popularization of nicotine salt technology has reduced the choking sensation, but has significantly increased the risk of nicotine addiction.

II. Lung health
The outbreak of EVALI lung injury cases in 2019 has put e-cigarettes on the map. Clinical data show that long-term use of e-cigarettes can lead to fine bronchitis and popcorn lung. In comparison, traditional smokers are more likely to develop COPD chronic disease. The World Health Organization warns that there is insufficient evidence to prove that e-cigarettes can be used as an effective means of quitting smoking.

III. Second-hand smoke controversy
Second-hand aerosols produced by vape device contain ultrafine particulate matter and volatile organic compounds, which spread indoors at three times the rate of traditional smoke. Research by the Hong Kong University of Science and Technology points out that these particles can carry heavy metal residues deep into human alveoli, posing a special threat to children and pregnant women.

IV. Addiction
The FDA report shows that flavor vape or flavour vape juice increase the probability of teenagers trying them by 67%. Attractive vape juice flavour such as fruit flavors and candy flavors blur the perception of harm and lead to nicotine dependence at a younger age. Neurologists emphasize that the sensitivity of the teenage brain to addictive substances is two times that of adults, which may trigger long-term problems such as attention deficit.

V. Regulatory dilemma
At present, there are significant differences in the global regulatory policies on e-cigarettes. Some countries have banned the sale of vape device and vape juice, but there are still areas where illegal modified devices are in circulation. Consumers should be wary of non-certified oils, which may contain dangerous additives such as vitamin E acetate.
