Effects of Cigar Flavors on Measures of Abuse Liability Among Young Adults

22 aprile 2019 aggiornato da: 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:

  1. own-brand CTC (positive control),
  2. original-flavored Black & Mild (B&M) cigar,
  3. apple-flavored B&M cigar,
  4. cream-flavored B&M cigar, and
  5. wine-flavored B&M cigar.

Descrizione

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.

  • 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).

Heart rate
Lasso di tempo: Heart rate will be recorded at one second intervals from session onset (minute zero of session) through minute 155 of the session (end of session).

Heart rate will be recorded at one second intervals from session onset (minute zero of session) through minute 155 of the session (end of session).
Blood pressure
Lasso di tempo: Blood pressure will be recorded at 5 minute intervals from from session onset (minute zero of session) through minute 155 of the session (end of session).
Each participant will attend 5 study sessions, each study session will include two bouts of product administration.Product administration will consist of 10 puffs with a 30-second interpuff interval (IPI; puff number and IPI will be directed and monitored by staff).
Blood pressure will be recorded at 5 minute intervals from from session onset (minute zero of session) through minute 155 of the session (end of session).
Puff Volume (ml)
Lasso di tempo: Puff Volume will be measured in seconds for each puff during product administration (10 puffs with a 30-second interpuff interval directed and monitored by staff)
The instrument senses flow-induced pressure drop across an orifice that is incorporated into the mouthpiece. Each participant will attend 5 study sessions, each study session will include two bouts of product administration. Puff Volume and Puff Duration will be used to calculate measures of Puff Flow Rate (Puff Volume/Puff Duration) and Total Puff Volume (Puff Volume per puff x 10 puffs).
Puff Volume will be measured in seconds for each puff during product administration (10 puffs with a 30-second interpuff interval directed and monitored by staff)
Puff Duration (seconds)
Lasso di tempo: Puff Duration will be measured in seconds for each puff during product administration (10 puffs with a 30-second interpuff interval directed and monitored by staff)

Descrizione del piano 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.
