The JUUL is a small and slender pen, maybe the length of a cigarette and a half, and it operates on refillable “pods” where the e-juice is stored and dispensed. One of these pods is said to have around the same amount of nicotine that a full pack of cigarettes offers. In my opinion, that’s a fairly high nicotine content, considering how easy it is to just vape anytime and how easy it could be to go over your normal nicotine intake when you smoked cigarettes.
