What is the purpose of this trial?

This trial explores a new method to help people quit smoking by integrating a smoke-free homes intervention into standard smoking cessation guidelines. The approach includes interactive mailings and coaching calls to encourage bans on smoking in homes and vehicles. It targets smokers who have had a cigarette in the past 30 days, are connected with a primary care provider in Georgia, and are not part of another quitting program. Researchers will check participants at six and twelve months to confirm smoking cessation using a saliva test. As an unphased trial, this study offers participants a unique opportunity to contribute to innovative smoking cessation strategies.

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the Smoke-Free Homes intervention is safe for smoking cessation?

Research has shown that making homes smoke-free is generally well-received by participants. One study found that when homes are smoke-free, people tend to smoke fewer cigarettes each day, indicating that these interventions are usually safe and can help people quit smoking.

Another study found that people who set smoke-free rules at home tried to quit smoking more often and were less likely to start again, demonstrating more attempts to stop smoking and fewer relapses. Additionally, strong support exists for creating smoke-free environments, indicating that people find this approach acceptable.

Overall, these findings suggest that the Smoke-Free Homes intervention is a safe way to help people stop smoking. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Smoke-Free Homes intervention because it offers a comprehensive approach to smoking cessation by targeting the home environment. Unlike standard treatments that primarily focus on individual behavior change, this intervention involves creating a smoke-free living space and connects participants to quitline support, enhancing accountability and motivation. This dual approach not only helps individuals quit smoking but also protects non-smokers in the household from secondhand smoke, providing a more holistic benefit. By validating outcomes through saliva cotinine levels, the intervention also ensures accurate assessment of smoking cessation, making it a promising alternative to conventional methods.

What evidence suggests that the Smoke-Free Homes intervention is effective for smoking cessation?

Research has shown that the Smoke-Free Homes program helps create smoke-free environments in homes and cars. One study found that more participants in the program reported completely banning smoking in their homes compared to those not in the program, with 30.4% versus 14.9% after three months. Other studies have also found that more participants in the program made their homes smoke-free than those who didn't join. Participants in this trial will receive the expanded Smoke-Free Homes intervention, which has led to bigger drops in daily smoking and more attempts to quit. These results suggest that this program can help smokers quit by encouraging smoke-free living spaces. ^{3 6 7 8 9}

Published Research Related to This Trial

Creating a smoke-free home (SFH) significantly increases the likelihood of quitting smoking among low-income smokers, with effects observed at both 3-month and 6-month follow-ups in a study involving 941 participants.

For smokers who did not quit, those with a SFH reported a greater reduction in daily cigarette consumption and more frequent quit attempts compared to those without a SFH, indicating that SFHs can support smoking reduction efforts.

Cessation and reduction in smoking behavior: impact of creating a smoke-free home on smokers. Haardörfer, R., Kreuter, M., Berg, CJ., et al.[2020]

A study involving 36 residents in permanent supportive housing revealed that while support for indoor smoking bans was modest (33.1%), a significant majority (77.8%) would not move due to a smoking ban, indicating potential feasibility for smoke-free policies.

Residents expressed interest in quitting smoking, but barriers such as co-use of tobacco with other substances and concerns about financial and housing stability need to be addressed to effectively implement smoke-free policies and cessation services.

The Smoke-Free Homes (SFH) Program was found to be acceptable and feasible for implementation across multiple 2-1-1 sites, with 70% of staff believing it contributed to more smoke-free homes in their communities.

Despite its perceived effectiveness, challenges such as sustainability, resource demands, and integration into existing workflows were significant barriers to successful implementation, highlighting the need for ongoing support and funding for future tobacco control initiatives.

This study will evaluate the effectiveness of an educational intervention aimed at 136 non-smoker women exposed to second-hand smoke at home, focusing on creating smoke-free environments through women's empowerment and education.

If successful, the intervention could lead to a significant reduction in second-hand smoke exposure at home, suggesting that integrating this educational program into routine care at primary health-care centers could be beneficial.

The 'Staying Free' program is a research-based smoking cessation model specifically designed for hospitalized patients, highlighting the importance of utilizing hospital stays as a chance to promote quitting smoking.

Insights gained from implementing this program suggest a systematic approach is essential for effectively integrating smoking cessation interventions into clinical practice and training for healthcare providers.

The 'Don't smoke in our home' trial, involving 218 women, showed that while brief counseling did not significantly enhance the implementation of totally smoke-free homes and cars, written materials alone led to modest increases in smoke-free environments among participants.

Despite the intervention, only a small percentage of smokers quit or reduced smoking indoors and in cars, indicating that while awareness and resources can help, more effective strategies are needed to achieve substantial behavior change.

Youths living in smoke-free homes (SFH) were significantly less likely to become established smokers over an 11-year period, with those in non-SFH being nearly twice as likely to start smoking compared to their peers in SFH.

The study found that the protective effect of SFH applied to both children and adolescents, regardless of whether their parents smoked, highlighting the importance of implementing household smoking bans to reduce smoking initiation among youths.
