Switching to Reduced Oxidant or Nicotine Content Cigarettes in Smokers
Switching to Reduced Nicotine Content Cigarettes or Reduced Reactive Oxygen/Reactive Nitrogen Species Cigarettes in Smokers
연구 개요
상세 설명
Researchers at Penn State Hershey are seeking healthy adult cigarette smokers between 21-65 who smoke any of the following brands on a regular basis: Marlboro Red, Marlboro Menthol, Pall Mall Red, Pall Mall Menthol, Kool Menthol, Salem Menthol, L&M Menthol, Pyramid Red, Newport Red, Newport Menthol.
If you smoke one of these brand styles on a regular basis you may be eligible to participate in a compensated short term study on health and smoking behavior at Penn State Hershey Medical Center.
Study participation lasts 22 days, with 4 study visits at the Medical Center. Smokers are asked to use their usual brand for one week and then switch to 1 of 3 brands for the remaining two weeks. The three brands participants are randomly assigned to after the first week of participation are either Group 1. reduced nicotine content cigarette (Spectrum Research Cigarettes) or Group 2. reduced oxidant cigarette (American Spirit) or assigned to Group 3. usual brand. Whichever group you are assigned to, you will be asked to smoke only these until the end of the study. All cigarettes following visit 1 will be provided free of charge.
Study overview:
Visit 1/ Duration: 60 minutes Provide a blood and urine sample Complete a 20 minute interview Use a simple, hand held smoking device to smoke all cigarettes for 2 days Collect cigarette butts on 1 day
Visit 2: Randomized Phase /Duration: 20-30 minutes Provide a blood and urine sample Complete a 10 minute interview Use a simple, hand held smoking device to smoke all cigarettes for 2 days Collect cigarette butts on 1 day
Visit 3/ Duration: 20-30 minutes Provide a blood and urine sample Complete a 10 minute interview Use a simple, hand held smoking device to smoke all cigarettes for 2 days Collect cigarette butts on 1 day
Visit 4/ Duration: 20-30 minutes Provide a blood and urine sample Complete a 10 minute interview Sign compensation form

실험적: Reduced Nicotine Cigarettes
Participants will be randomized to receive low nicotine cigarettes to replace their usual high nicotine brand.
|
Human topography data will show if smokers smoke their cigarettes differently from baseline following randomization.
Select biosamples of participants will be used to analyze how biomarkers differ among groups
