The reasons for banning e-cigarettes but not cigarettes are as follows:
1. E-cigarettes are not completely harmless. Although there are indeed fewer harmful substances than cigarettes, the increase in nicotine content also makes electronic cigarettes more harmful.
2. High cigarette tax. There are many smokers of cigarettes, and cigarettes pay the most taxes to the country every year. If e-cigarettes become popular, tax revenue will be reduced, and the price of cigarettes will fluctuate too much.
