Smoking causes 500 thousand Americans to die each year and is the leading cause of preventable death and disability in the United States. Although the number of smokers has reached an all-time low, the situation of the smoking population is still worrying, especially those with psychological problems and without medical insurance.
Is the prevalence of electronic cigarettes leading to a decline in the number of smokers in the United States? CDC does not think so. Although many e-cigarette manufacturers say they can help smokers get rid of nicotine altogether and promote e-cigarettes as tobacco substitutes. But CDC says there is not enough rigorous long-term research to show that electronic cigarettes help people quit smoking.
Brian King, a CDC smoking and health office worker, said: "There is still insufficient evidence that e-cigarettes can effectively help people quit smoking." King said that if smokers move from traditional cigarettes to e-cigarettes on a large scale, the number of e-cigarette users will increase as the number of smokers decreases. However, the opposite result was obtained after investigation. In 2017, about 2.8% of adults used electronic cigarettes, down from 3.4% in 2015.
