Brief summary
This is a single-center, exploratory positron emission tomography (PET) study of deposition, disposition and brain uptake \[11C\]nicotine when given to smokers as two different formulations via mybluTM e-cigarette system.
Interventions
1-2 puffs of each 3-5 seconds duration taken from myBluTM with Formulation 1, with inhalation of the vapour into the lungs
1-2 puffs of each 3-5 seconds duration taken from myBluTM with Formulation 2, with inhalation of the vapour into the lungs

Outcome results
Brain PET
Peak accumulation of nicotine deposited in the brain during 30 minutes after product administration, using dynamic PET Digital Imaging and Communications in Medicine (DICOM) images over the brain
Time frame: 30 minutes
Population: Four subjects underwent a brain \[11C\]nicotine PET/CT scan, but the tracer inhalation failed for two of the subjects. Consequently, only two \[11C\]nicotine scans could be used for evaluation, one after inhalation of Formulation 1 and one after inhalation of Formulation 2.
