Effects of Cigar Flavors on Measures of Abuse Liability Among Young Adults
22 avril 2019 mis à jour par: Virginia Commonwealth University
This study involves 25 current young adult combustible tobacco cigarette (CTC) smokers who will complete 5 Latin square ordered, within-subject, laboratory conditions that differ by the tobacco product smoked:
- own-brand CTC (positive control),
- original-flavored Black & Mild (B&M) cigar,
- apple-flavored B&M cigar,
- cream-flavored B&M cigar, and
- wine-flavored B&M cigar.

La description
Inclusion Criteria:
- To be included, participants must be healthy, as determined by self-report and heart rate/blood pressure (HR/BP) check, between the ages of 18-25, and willing to provide informed consent.
- They must agree to attend the lab and abstain from tobacco/nicotine as required, to use the designated products, and to follow the study protocol.
- Participants must also be regular CTC smokers (≥5 cigarettes/day for past 3 months) naïve to cigar products (smoked no more than 10 cigar products of any type in lifetime) who can provide a semi-quantitative urine cotinine result of ≥3 at screening (NicAlert test).
Exclusion Criteria:
- Individuals with a self-reported history of chronic diseases or psychiatric conditions will be excluded.
- Other exclusion criteria are: history of or active cardiovascular disease, current oral health problems or injuries, low/high BP, seizures, regular prescription medication use (other than vitamins or birth control), and past month use of cocaine, opioids, benzodiazepines, and methamphetamine (self-report).

Description du régime IPD
Once appropriate, a completely de-identified data set will be created that obfuscates any variable that might potentially be used to identify an individual study participant.
In accordance with HIPAA definitions for public data sharing, the investigators will use standard acceptable processes that include removal of identifiers, translation of dates and ages to delta time values, assignment of random study identifiers, and any other methods acceptable at that time.
A data sharing agreement will be required for release of any data.
Individuals requesting a copy of study data will need to submit a detailed research plan that includes the purpose of the proposed research, the variables required, the duration of the analysis phase, IRB approval with FWA information, investigator training in human subjects, and other approvals specific to the individual datasets.
