Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this proposal is to test the overall hypothesis that e-cigarettes (ECs) provide efficient nicotine delivery to the brain and arterial blood in non-EC-naïve smokers and e-cigarette users and that EC liquid characteristics modulate this effect. This study will test the hypothesis through complementary methods that include \[ \[18F\]NCFHEB (aka \[18F\]Flubatine) PET neuroimaging, arterial blood nicotine measurements, and subjective drug effects assessments.
