Effects of Electronic Cigarette Settings and Liquid Concentrations in Cigarette Smokers and Electronic Cigarette Users

The purpose of this research study is to find out how different types of electronic cigarettes (ECIG) settings, combined with e-liquids of differing nicotine concentrations, affect blood nicotine levels, use behavior (how users puff), and how users feel.

Inclusion Criteria--participants must be:

• healthy (determined by self-report)
• between the ages of 18-55
• willing to provide informed consent
• able to attend the lab and abstain from tobacco/nicotine as required and must agree to use designated products according to study protocol

Exclusion Criteria:

• Women if they are breast-feeding or test positive for pregnancy (by urinalysis) at screening.

Some study details about the eligibility criteria are purposely omitted at this time to preserve scientific integrity. Full details will be posted at the conclusion of the study.
