Cigarette Smoking-Related Carcinoma, E-Cig Use
Conditions
Brief summary
This study evaluates the amount of nicotine, cannabis, and toxicants linked to the use of nicotine e-cigarette and/or cannabis products in the blood and urine of young adult users as well as the cannabis and nicotine use behaviors of consumers.
Detailed description
PRIMARY OBJECTIVE: I. To evaluate differences in self-reported nicotine and cannabis use behaviors and biomarkers of exposure to toxicants and carcinogens by product use status, to generate effect sizes required to calculate sample sizes needed for a larger study.
Interventions
OTHEREffectiveness of different recruitment approaches
Subjects will asked which type of recruitment material they've seen when completing the screening survey
OTHERChoice of study completion locations
subjects will choose location when coordinator calls to schedule appointment
OTHERCannabis Engagement Assessment
Self reported measure of current cannabis use that contains 30 questions assessing quantity, frequency of use and method of consumption in the past 30 days.
OTHERE-cigarette dependence Scale
A 22-item questionnaire measuring e-cigarette dependence. Higher scores indicate greater dependence.
OTHERNicotine dependence Scale
Self reported measure of current nicotine use that contains 27 questions assessing quantity, frequency of use in past 6 months
OTHERCo use practices QUestionnaire
Self reported measure of nicotine and cannabis use that contains 25 questions assessing quantity, frequency and practices of use in past 30 days

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Differences in biomarker levels across groups | 1 study session lasting 1 hour | Will compare the mean biomarker levels between groups using a one-way ANOVA model, with Bonferroni-adjusted pairwise comparisons, as appropriate. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Differences in self reported nicotine and cannabis use behaviors | 1 study session (1 hour) | Self reported questionnaire |
| Differences in psychosocial characteristics by group | 1 study session (1 hour) | Will be compared between groups using the appropriate general linear models. All model and test assumptions will be verified graphically, with transformations applied as appropriate. |
| Study interest | Up to 1 year | Study interest and eligibility Measured via number of contacts to inquire about the study, and number of eligible applicants. The eligibility and interest rates of the individuals approached and the completion rates of the enrolled individuals will be estimated overall and by relevant factors (recruitment channel, type of advertisement) using 90% credible regions obtained by Jeffrey's prior method. |
| Recall of study recruitment advertisement type | 1 study session (1 hour) | Analyses will be primarily descriptive to evaluate the reach and effectiveness of recruitment strategies. Key endpoints will be summarized overall and by relevant factors (ex., recruitment channel) using the appropriate descriptive statistics, with comparisons made using the Mann-Whitney U and Kruskal Wallis or Fisher's exact and Pearson chi-square tests, as appropriate. |
| Recall of recruitment channel | 1 study session (1 hour) | Will include where study information/advertisement was viewed. Analyses will be primarily descriptive to evaluate the reach and effectiveness of recruitment strategies. Key endpoints will be summarized overall and by relevant factors ex., recruitment channel) using the appropriate descriptive statistics. |
| Completion method chosen by participants | 1 study session (1 hour) | On campus versus off-campus |
