Cigar Packaging Study

This laboratory-based study will aim to enroll 50 current cigarillo users to complete a 20-day, randomized, parallel design protocol. After a 5-day period of smoking their own preferred brand of cigarillos, participants will begin a 15-day experimental period when they will be randomized to one of two conditions, 2 cigarillos per pack versus 4 cigarillos per pack, to examine how quantity per pack affects use patterns, including daily consumption and cigar smoking topography. Participants will be asked to attend 2 in-person sessions on Days 5 and 20. On Days 0, 9, 12 and 16 participants will complete sessions with research staff remotely (i.e. by phone or video call). Sessions will occur every 3-5 days, for a total of 6 sessions across 20 days.

Inclusion criteria

• Current cigarillo smoker (i.e., smoked at least 50 cigarillos in their lifetime)
• Not currently undergoing smoking cessation treatment or planning to quit smoking over the duration of the study (~3 weeks).
• Plan to live in the area for the duration of the study.
• Willing to use study provided cigarillos.
• Capable of giving informed consent, which includes compliance with the requirements and restrictions listed in the combined Informed Consent and HIPAA form.

Exclusion criteria

• Use of any nicotine-containing products other than cigarillos or cigarettes. Participants reporting isolated use of other nicotine containing products less than 5 times per month are eligible to participate.
• Current or impending enrollment in a smoking cessation program. Further, participants will be excluded for an attempt to quit smoking over the duration of the study period.
• History of substance abuse (other than nicotine dependence) in the past 12 months and/or currently receiving medical treatment for substance abuse. Attendance at alcoholics anonymous or narcotics anonymous meetings will not be considered medical treatment for the purposes of this protocol.
• Current alcohol consumption that exceeds 25 standard drinks/week.
• Women, including all individuals assigned as "female" at birth, who are pregnant, breast feeding, or planning a pregnancy over the duration of the study period.
• Any impairment including, but not limited to, visual, physical, and/or neurological impairments preventing the proper completion of the study procedures. Notable impairments will be evaluated on a case-by-case basis by the Principal Investigator and/or the Study Physician.
• Serious or unstable medical condition. Applicable conditions will be evaluated on a case-by-case basis by the Principal Investigator and/or the Study Physician.
• Lifetime history or current diagnosis of COPD, cardiovascular disease, or heart attack.
• Lifetime history of schizophrenia, psychosis, and/or bipolar disorder.
• Current diagnosis of active major depression. Participants who maintain a diagnosis of major depression who have not experienced any major depressive episodes in the past 6 months and are stable on antidepressant medication(s) are eligible to participate.

Additional, general reasons for exclusion include:

• Past, current, anticipated, or pending enrollment in another research program over the study period that could potentially impact subject safety, study data, and/or the study design as determined by the Principal Investigator and/or Study Physician.
• Any circumstance, medical condition, illness, disorder, adverse event (AE), or concomitant medication that could compromise participant safety or significantly impact study performance as determined by the Principal Investigator and/or Study Physician. Participants may be withdrawn for any of the aforementioned reasons at any point throughout the study.
• Significant non-compliance with protocol and/or study design as determined by the Principal Investigator and/or Study Physician. Participants may be withdrawn at any point throughout the study.
