Outcome Measures

Primary Outcomes (4)

  • Daily Cigarillo Consumption

    Daily cigarillo consumption will be assessed by participant self-report throughout the 20-day study duration and verified through the collection of spent cigarillo "tips/ends" for all cigarillos smoked throughout the 15-day experimental period.

    Day 0 through Day 20

  • Smoking Topography

    Topography data will be produced through a standardized video scoring procedure. Participants will video recorded to collect smoking topography data for all cigarillos smoked throughout the 15-day experimental period.

    Day 5 through Day 20

  • Total Nicotine Equivalents

    Urine collected at Day 5 and Day 20 will be assessed for changes in total nicotine equivalents, nicotine plus its primary metabolites, across the experimental study period (Days 5-20). Total nicotine equivalents will be measured in nanograms per milliliter (ng per mL).

    Days 5 and 20

  • Total NNAL

    Urine collected at Day 5 and Day 20 will be assessed for changes in NNAL, a biomarker of carcinogen exposure, across the experimental study period (Days 5-20). Total NNAL will be measured in nanograms per milliliter (ng per mL).

    Days 5 and 20

Secondary Outcomes (5)

  • Subjective Cigarillo Ratings (Visual Analog Scale [VAS] of Cigarillo Characteristics)

    Day 5 through Day 20

  • Cigarillo Craving (Questionnaire on Smoking Urges [QSU])

    Day 0 through Day 20

  • Cigarillo Withdrawal (Withdrawal Symptom Checklist [WSC])

    Day 0 through Day 20

  • Cigar Evaluation (Cigar Evaluation Scale [CES])

    Day 5 through Day 20

  • Sensory Measure (Sensory Questionnaire [SQ])

    Day 5 through Day 20

Study Arms (2)

2 cigarillos per pack

EXPERIMENTAL

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 receive 2 cigarillos per pack.

Other: Package Quantity (cigarillos)

4 cigarillos per pack

EXPERIMENTAL

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 receive 4 cigarillos per pack.

Other: Package Quantity (cigarillos)

Interventions

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.

Eligibility Criteria

Age21 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.
  • Able to communicate fluently in English (i.e., speaking, writing, and reading).

You may not qualify if:

  • 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.
  • 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.

Intervention Model
PARALLEL
Model Details: This project will recruit current cigarillo users to 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.
