I'm a researcher working on Smokeless Tobacco Use. I'm looking for Smokeless Tobacco Users in Oklahoma who could help me regarding a research study.
We are studying Smokeless Tobacco Dependence. The participants have to fill out a questionnaire and provide a saliva sample. We will mail the study material and the participants will send it back to us in pre-paid envelope.
Participant should be Smokeless Tobacco Users, 18years or older, currently non-smoker, living in Oklahoma.
Confidentiality of the participants will be maintained.
