There are very few countries and regions that regulate the production of E-cigarettes. Brazil, Greece, Israel, the United Arab Emirates, and some local governments in India have banned E-cigarette production. Chile and Malaysia have also introduced management regulations on E-cigarette production. The control of E-cigarettes in China does not exist, and the product quality has no standards, meaning that the E-cigarette industry is in chaos. The quality of E-cigarette products is uneven and without security guarantees, and the hidden dangers behind this situation are worrying . In a report on the adverse effects of E-cigarette smoke issued by the United States Food and Drug Administration (FDA), it was pointed out that about half of the tobacco-related adverse events reported in more than 100 tobacco reports were related to E-cigarettes .
