Physical Changes After Switching to E-Cigarettes

Many friends are very concerned about the effects of e-cigarettes. For instance, people often want to know about the physical changes after switching to e-cigarettes. Such questions require real experiences to find answers, so the Heated Tobacco Information Network has collected numerous user experiences and studies. Let's take a look.
 
Physical changes after switching to e-cigarettes: A UK study

According to a report by the Daily Mail, a new study shows that among smokers who successfully switched to e-cigarettes, two-thirds claim they suffer from fewer respiratory diseases. Researchers state there is clear evidence that vaping does not cause lung infections like traditional cigarettes do.

Queen Mary University of London conducted an online survey of 941 respondents, assessing the subjective changes in lung diseases among smokers who had switched to e-cigarettes for at least two months. The study was published in the journal Addiction Research & Theory. The report shows that 66% of respondents reported improvement in respiratory symptoms; 29% reported no change, and 5% reported worsening symptoms.

There is no doubt that e-cigarettes are safer than traditional cigarettes, but some smokers still believe they are dangerous. This misconception includes a study on mice that falsely claims vaping may increase susceptibility to infections. However, studies on human e-cigarette users prove otherwise. Peter Hayek, a professor at Queen Mary University of London and the lead author of the report, stated, "Because this study is based on subjective reports, it needs to be interpreted with caution and requires objective measures for further research. However, the current results provide ample data to demonstrate that vaping does not increase the risk of infection; in fact, it may reduce it.
 
Physical changes after switching to e-cigarettes: Real experiences from smokers

Jimmy from the UK

I switched to e-cigarettes and stopped smoking traditional cigarettes immediately. It's been three months, and now I find myself disgusted by people smoking indoors, just like non-smokers. The smell is really unpleasant, like burnt cotton from the atomizer. So quitting smoking relies on willpower; it mainly depends on your subjective awareness. I've gained 20 pounds in three months since quitting, and my appetite has increased (do fruit-flavored e-liquids have an appetite-stimulating effect...?) Now, it's not just about quitting smoking; I need to lose weight. I wish everyone success in quitting smoking.

I develop e-liquids, and before that, I worked on food flavor development. From my experience, the ingredients in e-liquids, apart from nicotine (and tobacco-flavored e-liquids also contain tobacco extracts), are mostly food-grade single ingredients or natural extracts. These ingredients can be found in the 2760 database (at least, all the ingredients in my product formulas, except for nicotine, can be found in the 2760 database). These components are present in the beverages, candies, cookies, and all foods we consume daily.

Physical changes after switching to e-cigarettes: Answers from Zhihu

After vaping for two years, I have noticed some changes, at least the people around me can see them.

Mom: You no longer smell like smoke.

Girlfriend: No more bad breath.

Friends: Your complexion has improved.

Myself: I no longer feel nauseous while brushing my teeth in the morning, and my teeth are no longer yellow.

The physical changes after switching to e-cigarettes have been shared from three perspectives. According to the UK study, switching to e-cigarettes leads to fewer respiratory diseases. From real smoker experiences, it seems that vaping has led to weight gain, which is uncertain whether it's a good or bad thing. The benefits mentioned by Zhihu users are quite realistic, mainly that there is no longer a smell of smoke.
