March 23, 2021 updated by: Cheerain HK Limited
A Randomized, Open-Label, Single-Center, Cross-Over Study of Adult Smokers to Assess Nicotine Uptake, Measures of Abuse Liability, and Puffing Topography With RELX Infinity Electronic Nicotine Delivery Systems (ENDS)
This study is being conducted to evaluate nicotine uptake and exposure, the abuse liability, and puffing topography associated with the use of an electronic nicotine delivery system ENDS with tobacco- and menthol-flavored e-liquids in current smokers.
