A new report from the National Academies of Sciences, Engineering, and Medicine says that e-cigarettes are considered to be less harmful than regular cigarettes.
However, the report says that e-cigarettes are still addictive.
According to the report, e-cigarettes have less toxins than regular cigarettes.
The report also found that e-cigarettes can cause teens and young adults to become hooked and raise their risk of becoming traditional smokers.
The vaping industry says the report has flaws and that e-cigarettes are a better alternative for smokers.
Despite the growing popularity of e-cigarettes, the long term risks of using them are still not known.
