Brief summary

A Ten Sequence, Open Label, Randomized Crossover Study Comparing Nicotine Pharmacokinetics of JUUL 1.7% and JUUL 5% Nicotine Salt Based ENDS Products, in Healthy Adult Smokers.

Detailed description

E-cigarettes may be an acceptable alternative to traditional cigarette smoking. In utilizing vaporization rather than combustion, the generation and inhalation of smoke and carbon monoxide (CO) may be reduced or avoided. JUUL has developed several nicotine based liquid blends for use in e-cigarettes. This study will provide an understanding of the levels of nicotine obtained with use of the company's 1.7% and 5% ENDS products.
