Reducing Tobacco-associated Lung Cancer Risk: A Randomized Clinical Trial of AB-free Kava

Description

Tobacco use is the leading cause of many preventable diseases, particularly lung cancer. Based on the national cancer data in 2020, Florida has the highest lung cancer incidence (18,150 cases) with the most deaths (10,580 deaths) among all the states in the United States. Unfortunately, around 16% of adults in Florida continue to smoke cigarettes due to its addictive nature and the limited success of current cessation strategies. Therefore, there is an unmet and urgent need for novel interventions to improve the success of tobacco cessation. If such an intervention can reduce tobacco-associated lung carcinogenesis, that will be more desirable. The ultimate goal of this study is to develop a safe and effective kava-based intervention to enable tobacco cessation and reduce lung cancer risk, which will improve the health of Floridians. This study will evaluate the compliance with a daily kava regimen among active smokers who have no intention to quit smoking. This study will also investigate whether kava use can reduce tobacco use and dependence, as well as tobacco-associated lung carcinogenesis.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * self-reported smoking at least 5 cigarettes/day for the past year with no intention to quit at time of screening visit
  • * expired carbon monoxide level of more than 8 ppm at recruitment
  • * willingness to participate in the proposed study, as indicated by signed informed consent
  • * access to a functional telephone
  • * expected presence in the study's geographical area for the next 4 months
  • * not currently enrolled in any smoking cessation programs per self-report
  • * female subjects of childbearing potential will be required to practice acceptable methods of birth control (the acceptable methods of birth control include birth control pills, Birth Control Shot, Birth Control Implant, Intrauterine Device \[IUD\], Diaphragm, and cervical cap)
  • * history of active cancer (other than non-melanoma skin cancer) within the past 2 years
  • * diagnosed with liver dysfunction or with previous liver diseases
  • * levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, or total bilirubin over limit of normal range at prescreen
