It turns out that all the questions are customized. This survey defines e-cigarette users as "using e-cigarettes at least once in the last 30 days." That is to say, whether it is a serious user who smokes every day, or a person who has tried once within 30 days and has never used an e-cigarette again, they are all called e-cigarette users. So are there any "e-cigarette users" who smoked for the first 29 days and started using e-cigarettes on the last day? Is it because cigarettes or electronic cigarettes are prone to fractures? None of the definitions used as research premises are correct, and the conclusion naturally has no meaning. The head of ACSH's life sciences section, CameronEnglish said sharply.

On this basis, conduct specific research. This research report published in the American Open Journal of Medicine shows that more than 5,500 adult e-cigarette users participated in a survey and found that the use of e-cigarettes can cause fragility fractures. These conclusions may seem terrible, but the logic is full of loopholes: the incidence of fragility fractures in e-cigarette users is higher = e-cigarette users are more likely to have fractures = e-cigarette users are osteoporosis = e-cigarette users cause bones Porosity-a typical slippage fallacy.

Is the user doing dangerous work? High incidence of fractures? Apart from electronic cigarettes, do fracture patients have other habits? Does the user have a history of fracture before using the e-cigarette? In learning logic, you can play a question mark for every equal sign. What's more serious is that some conclusions of the research also contradict the authoritative scientific conclusions that have been internationally recognized.

CameronEnglish said that because this study shows that "the prevalence of dual e-cigarette users in cigarettes is higher than that of smokers." Since 2015, the Department of Public Health of the United Kingdom has confirmed that e-cigarettes can reduce the hazards of cigarettes by 95%. How can the prevalence of cigarettes be higher if users abandon the more harmful cigarettes?

He once studied this research and found that this research was completely contradictory. Data shows that the incidence of fragility fractures among e-cigarette users is higher than that of current smokers. According to the results of the study (e-cigarettes are a causative factor), stopping e-cigarettes should not be easy to break.

Survey data shows that the prevalence of former users who stopped using e-cigarettes (Formerusers) is higher than that of current e-cigarette users (Currentusers).

In fact, the researcher has summarized the existing limitations in the summary, including not distinguishing the e-cigarette brands used by the respondents, the time of use, and a more specific comparative analysis. However, both domestic and foreign media have focused on the sensational conclusion that "e-cigarettes cause osteoporosis".

"The researcher once said: "The potential impact of our findings on public health is convincing. Although I am humble, any conclusions drawn from this research are wrong. Even if e-cigarettes cause osteoporosis, we still need to conduct more scientific research. If there is such a thing, English said.
