Is this trial a fit for you?

Likely a good fit

Ideal participants are 18-26-year-olds who use ENDS at least 4 days per week over the past month, report moderate-to-high interest in quitting or reducing (≥6/10), are not pregnant or breastfeeding, and do not have recent severe psychiatric or substance use disorders.

Probably not a fit

Those unlikely to benefit include pregnant or breastfeeding people, individuals with recent major psychiatric or severe substance use disorders, people already using smoking-cessation medications, older adults, or those not interested in quitting ENDS.

What this trial studies

This pilot interventional study develops and pilots an mHealth intervention that translates proven smoking-cessation content and medication guidance for young adult ENDS users, including dual users. Participants will be recruited at the University of Chicago and randomized to the EQUIP mobile program or to standard care, with enrollment focused on 18-26-year-olds who use ENDS frequently and want to quit or reduce. The protocol combines digital behavior-change tools, user feedback from focus groups, and optional pharmacotherapy information to refine the intervention. Primary outcomes will include feasibility, engagement, and preliminary changes in ENDS use.

Why it matters

Potential benefit: If successful, this approach could increase quit or reduction rates and provide scalable, tailored support and medication guidance for young adult ENDS users.

How similar studies have gone: Mobile cessation programs and pharmacotherapy have shown moderate success for combustible cigarette smokers, but rigorous trials specifically targeting ENDS or dual users—particularly young adults—are limited, so this is a relatively novel application.
