Detaljert beskrivelse
PRIMARY OBJECTIVE:
I. To determine the between-session reliability of oculomotor biomarkers during standardized nicotine administration in daily e-cigarette users.
SECONDARY OBJECTIVES:
I. To evaluate the association between oculomotor (OM) responses to nicotine and behavioral economic indices of reinforcing value.
II. To assess the relationship between oculomotor changes and nicotine withdrawal relief.
OUTLINE:
Participants abstain from nicotine for at least 12 hours and caffeine products for at least 2 hours, as well as obtain sleep for at least 5-6 hours before each study visit. Participants self-administer 5% nicotine non-mint menthol pods via an e-cigarette device using a guided standardized puffing routine over 5 minutes on visit one. At least 48 hours later, participants complete the same 5-minute guided puffing routine as in visit one and then use an e-cigarette as they normally would over 30 minutes at visit two. Participants also complete eye movement testing and undergo blood sample collection during each visit.

Eksperimentell: Basic science (e-cigarette smoking, eye movement testing)
Participants abstain from nicotine for at least 12 hours and caffeine products for at least 2 hours, as well as obtain sleep for at least 5-6 hours before each study visit.
Participants self-administer 5% nicotine mint menthol via an e-cigarette device using a guided standardized puffing routine over 5 minutes on visit one.
At least 48 hours later, participants complete the same 5-minute guided puffing routine as in visit one and then use an e-cigarette as they normally would over 30 minutes at visit two.
Participants also complete eye movement testing and undergo blood sample collection during each visit.

Change in Minnesota Nicotine Withdrawal Scale scores
Tidsramme: From baseline and following nicotine administration, assessed up to completion of visit 2, up to 3 weeks

The Minnesota Nicotine Withdrawal Scale (MNWS) will asses nicotine withdrawal and craving, anger/irritability, anxiety, depressed mood, restlessness/difficulty concentrating, increased appetite, sleep problems, and somatic symptoms (nausea, constipation, sore throat, dizziness, coughing).
Scores range from 0 to 4 with higher scores indicating greater levels of withdrawal.
