Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Study participants will receive 3 inhaled doses of the investigational nicotine replacement therapy (NRT) product as a self-administered dose via the Miist Nicotine Inhaler.
Study participants will receive training on how to use the Miist Nicotine Inhaler from the site research team. Training with a sham device will take place at the time of screening, at clinic check in and prior to each dose. The site research team will supervise each dose.
Study participants will be instructed to fully exhale. A flashing blue light will be visible when the device is ready. They will place the mouthpiece in their mouth and inhale firmly and deeply such that the steady blue light remains on, increasing their inhalation effort if the blue light stops or slowing their inhalation if a red light flashes. At the end of the dose delivery, the steady blue light will go off and the motor in the device will stop. The participant is to hold their breath for 5 seconds prior to exhaling and ending the dose.
The doses will be administered in increasing order of strength of nicotine, starting from 0.08 mg and increasing to 0.16 mg then 1.15 mg with a 120 minute (+15 minutes) washout period between each dose level.
