Abstract: Studies have demonstrated that the awareness rate of e-cigarettes is high, but the rate of e-cigarettes-related health knowledge is low among the public; social network is one of main ways for the public to know about e-cigarettes. Data from all over the world indicated that e-cigarettes is widely consumed currently among young populations and main reasons for the use of e-cigarettes are to quit smoking, to reduce tobacco hazards, to prevent re-smoking, being curious, and fashion design of e-cigarettes products. Strategies proposed by the researchers to cope with the prevalence of e-cigarettes consumption included promoting education on e-cigarettes-related health knowledge, strengthening supervision on e-cigarettes, and implementing effective interventions to reduce e-cigarettes consumption in key populations.
