Flavors and E-cigarette Effects in Adolescent Smokers- STUDY 1

April 30, 2020 updated by: Yale University
This study is to examine if inhaled doses of menthol that produce low and high cooling effects change the appeal of e-cigarettes containing low and high doses of nicotine in adolescent smokers. The hypothesis is that the combination of nicotine and menthol, when compared with menthol or nicotine alone, will result in greater increase in liking of an e-cigarette and greater reduction in nicotine withdrawal.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Tobacco Flavor
In this arm, subjects will receive tobacco flavor- without nicotine (placebo). Participants will then be exposed to 3 levels of a menthol additive in random order: no dose, low dose and high dose.
Other: Low Dose Menthol
A low dose of menthol will be added to the tobacco flavor.
Other: High Dose Menthol
A high dose of menthol will be added to the tobacco flavor.
Active Comparator: Low Dose Nicotine
In this arm, subjects will receive a low dose of nicotine (6 mg/ml) added to the tobacco flavor. Participants will then be exposed to 3 levels of a menthol additive in random order: no dose, low dose and high dose.
Other: Low Dose Menthol
A low dose of menthol will be added to the tobacco flavor.
Other: High Dose Menthol
A high dose of menthol will be added to the tobacco flavor.
Drug: Nicotine
Participants will receive no nicotine, low dose nicotine (6 mg/ml) or high dose nicotine (12 mg/ml)
Active Comparator: High Dose Nicotine
In this arm, subjects will receive a high dose of nicotine (12 mg/ml) added to the tobacco flavor. Participants will then be exposed to 3 levels of a menthol additive in random order: no dose, low dose and high dose.
Other: Low Dose Menthol
A low dose of menthol will be added to the tobacco flavor.
Other: High Dose Menthol
A high dose of menthol will be added to the tobacco flavor.
Drug: Nicotine
Participants will receive no nicotine, low dose nicotine (6 mg/ml) or high dose nicotine (12 mg/ml)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Liking/effect score of the e-cigarette
Time Frame: Every 30 min for 120 min during lab session
The Drug Effects Questionnaire (Soria et al) will be used to ask about participants' liking/effect of the e-cigarettes smoked during the 4 bouts of e-cigarette puffing during the lab session to determine which menthol dose is most preferred. A linear mixed-effects regression model wil be used with nicotine group (none, low, high) as between-subject factor, and menthol dose (none, low dose, high dose) as within-subject factor.
Every 30 min for 120 min during lab session

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximum value of money at which the e-cigarette is chosen over money
Time Frame: Every 30 min for 120 min during lab session
E-cigarette value will be determined using the Multiple Choice Procedure (Griffiths et al, 1993) to determine the reinforcing value of the e-cigarette. The MCP involves sampling the e-cigarette and then making a discrete choice between the e-cigarette or a series of monetary values.
Every 30 min for 120 min during lab session
Change scores from baseline in Nicotine Withdrawal
Time Frame: Every 30 min for 120 min during lab session
The Minnesota Nicotine Withdrawal Scale (Hughes et al,1986) will be used to assess the magnitude of change in nicotine withdrawal symptoms during the lab session
Every 30 min for 120 min during lab session
Change scores from baseline in Tobacco Craving
Time Frame: Every 30 min for 120 min during lab session
The Brief Questionnaire on Smoking Urges (Tiffany & Drobes,1991) will be used to assess the magnitude of change in tobacco craving during the lab session
Every 30 min for 120 min during lab session
