Innovative Study Helps Smokers Practice Quitting

UW-CTRI has commenced a new pilot study designed to encourage participants to practice the act of quitting smoking for up to a day at a time, then return to smoking by only puffing every 30 seconds without inhaling.

“The whole idea behind this paced puffing is that we want them to practice quitting, but not relapsing,” said Principal Investigator Dr. Danielle McCarthy, UW-CTRI Associate Director of Research. “We want them to go back in a way that’s not very rewarding, not aversive; we’re not trying to make them sick, just trying to make it slightly unpleasant to go back to smoking.”

The idea is that the participant will apply lessons learned to a full quit attempt in the future—just not during this 15-day pilot study. The Pilot Study of Practice Quitting Smoking and Paced Cigarette Puffing will ultimately enroll 20 people. More than 80 smokers have volunteered and are being screened, with a few attending their first visits.

The first visit is in person at the UW-CTRI Clinic in Madison. Participants learn about the study, consent, answer questions, and learn how to practice quitting and puff from cigarettes when prompted without inhaling smoke into their lungs.

Then, every other day for two weeks, UW-CTRI researchers will call participants at their usual wake-up times to ask questions and instruct them to either practice quitting or just monitor their smoking closely that day. Later the same day, researchers will call to ask how things are going and, if the person practiced quitting, ask participants to puff from up to three cigarettes without inhaling. Researchers will ask participants to go just a bit longer not smoking than the participants previously thought they could go. Researchers will monitor them via Facetime, Skype, Google chat, or by phone if they cannot video chat.  After 15 days, the study concludes and researchers will gather feedback.

UW-CTRI isn’t new to using technology to track participant behavior. Previous studies have used gadgets to monitor use of medication, to automatically call participants and collect data, and to interact via phone apps. But this study uses a unique combination of apps, devices, and video monitoring.

Researchers will monitor carbon monoxide levels to ensure participants aren’t inhaling while puffing, using a device called the iCO. Participants breathe into the device, which analyzes breath, carbon monoxide, and provides results via the Smokerlyzer app.

Participants do not have to quit smoking to participate but, if they declare an interest in quitting, researchers will congratulate them and refer them to quit-smoking resources.
