Brief Summary
This study is designed to examine how the nicotine content of cigarettes and the nicotine concentration and flavors in e-liquids influence responses to and use of these products in adolescent smokers. Participants will complete a total of six sessions (an in-person screening/baseline session and five lab sessions.

Eligibility Criteria
You may qualify if:
- Ages 15-20
- Adolescents who report current daily or near daily cigarette smoking for at least 3 months
- Must have used an electronic nicotine device on a minimum of two lifetime occasions.
- Breath Carbon Monoxide (CO) levels \> 5 ppm (if \< 5 ppm, then cotinine assay via NicAlert Strip = \> 3)
- Speak, comprehend, and read English well enough to complete study procedures
You may not qualify if:
- Unwilling to use research cigarettes or ENDS as part of the study
- Intention to quit smoking in the next 30 days
- Using tobacco products (other than ENDS or roll-your-own tobacco) \> 15 days in the past 30 days.
- Any medical or psychiatric condition in which participation is likely to post a significant threat to health or for which the condition could interfere with the ability of the participant to fully participants (as determined by the LMP)
- Self-reported illicit use of any drug except marijuana \> 10 days in the past 30 days
- Binge drinking alcohol (\>10 days in the past 30 days, \>4/5 drinks in a 2-hour period (female/male))
- Pregnant or breastfeeding
- CO reading \> 80 ppm
- Systolic BP outside the range of 90-159, diastolic BP outside the range of 50-99, or heart rate outside the range of 45-104. Participants failing for any of these criteria will be allowed to re-screen once per criterion.
- Indicating Yes on Questions 4-6 on the MINI with a suicide attempt in the past 2 years (if within the past 2-10 years, LMP approval required).
- Having participated in another research study during the past year in which they were switched to reduced nicotine cigarettes for longer than one week.
