The Risks of Vaping: What Harm Can E-Cigarettes Do to the Body?
Let’s start with the conclusion, which is my heartfelt advice
1. E-cigarettes are only suitable for "adult smokers who cannot quit smoking on their own" (keywords: adults, smokers, cannot quit).
2. If you do not belong to the above group, e-cigarettes will not help you. Fresh air is your only healthy choice.
3. Currently, it can be said that the harm of e-cigarettes is far less than that of cigarettes. (Because there is no tar and carbon monoxide)
4. E-cigarettes cannot help you quit smoking; they can only serve as a substitute for cigarettes. I recommend e-cigarettes as "harm-reducing cigarettes of various flavors." (Because currently, pod devices use nicotine salt e-liquids, and nicotine reduction therapy does not exist).
5. E-cigarette products are highly homogenized, and brand value has not been highlighted. Recommended purchasing criteria: ① visually appealing ② good to vape ③ not prone to leaking ④ reasonable price.

Introduction to E-Cigarette Safety
References: WHO report on the regulation of e-cigarettes and similar products.
Reference: UK Public Health Department's safety report on e-cigarette products.
Reference: Public health consequences of e-cigarettes, National Academies of Sciences, Engineering, and Medicine.
Conclusions from the above materials:
(1) Stop selling e-cigarettes to non-smokers and minors.
(2) The harmfulness of e-cigarettes has not been confirmed.
(3) The health risks of e-cigarettes have been exaggerated.
(4) The effectiveness of e-cigarettes in quitting smoking has not been verified (personal opinion: cannot quit smoking, can substitute).
(5) E-cigarettes reduce harm by 95% compared to cigarettes (I partially agree with this view).
How E-Cigarettes Reduce Health Risks for Smokers
① The main harms of smoking are tar, carbon monoxide, heavy metals, and nicotine.
② The root of nicotine addiction is nicotine, not tar.
The basic opinion on nicotine: "The harm of nicotine is minimal, but it is still less than tar."
③ E-cigarettes contain nicotine but no tar.
From the above, it can be concluded: e-cigarettes are relatively enjoyable and have lower harm.
How to View E-Cigarette Products
E-cigarettes/cigarettes ≈ sugar-free cola/cola.
Sugar-free cola: The sugar in cola is the main culprit, and carbonation is an accomplice. They cannot be separated; first, punish the main culprit.
E-cigarettes: The tar in cigarettes is the main culprit, and nicotine is an accomplice. They cannot be separated; first, punish the main culprit.
