Most e-cigarettes contains nicotine !!!!!
The e-liquid in all JUULs and most e-cigarettes contains nicotine, the same addictive drug that is in regular cigarettes, cigars, hookah, and other tobacco products. However, nicotine levels are not the same in all types of e-cigarettes, and sometimes product labels do not list the true nicotine content.
The e-cigarette brand JUUL has a significantly higher amount of nicotine per puff than some other types of e-cigarettes and cigarettes. Because of this, JUUL and JUUL-like products may be more addictive than other types of e-cigarettes. Some reports say kids have become physically dependent on nicotine by using JUULs.
There are some e-cigarette brands that claim to be nicotine-free but have been found to contain nicotine.
