Comparison of Pharmacokinetic Parameters Between Adopters of Electronic Cigarettes and a Historical Sample of Combustible Cigarette Smokers

This is an observational, open-label study to assess the nicotine pharmacokinetic (PK) parameters over a 6-hour period in adopters of electronic cigarettes with respect to an in-clinic 10-minute ad libitum period following a 12-hour tobacco and nicotine abstinence. In addition to PK parameters, subjective effects of urge for product will be assessed over a 6-hour period concurrently with the collection of the PK blood samples following a protocol defined schedule. The results of this study will be compared to historical PK and urge for product data obtained from smokers as well as naïve and short-term users of electronic cigarettes. In addition to the PK parameters and urge for product outcomes, plasma will be assessed for cotinine concentration prior to the 12-hour abstinence period.
