Introduction

The first four modules explained why young men in a composite Plains county take up and keep using oral nicotine: first use is often unplanned and driven by willingness and favorable images of users, older men and teammates pass the habit along, work and team settings supply the occasions, and local values and misperceived norms make use seem normal. Before designing a response in Module 6, this paper reviews what research says about interventions. It focuses on studies of smokeless tobacco among young men, since direct evidence on nicotine pouch interventions is still sparse, and appraises each for design, use of theory, results and fit with the county. The review covers school and college team interventions, a national media campaign and cessation treatment.

Search and Appraisal Approach

Studies were found by searching PubMed and the Cochrane Library with terms covering smokeless tobacco, snuff, spit tobacco, nicotine pouches, prevention, cessation, adolescents and young adults, with preference for randomized trials, systematic reviews and formative research that informed tested interventions. Each study was appraised on four questions: how strong the design is, whether and how theory guided the intervention, what the results show and how closely the setting and population resemble young men in a rural ranching and oilfield county. The review is narrative rather than systematic and does not attempt a pooled estimate.

High School Baseball: A Cessation Success

Walsh et al. (2003) conducted a cluster-randomized trial in 44 rural California high schools, enrolling 1,084 baseball athletes, 93% of those eligible. The intervention included oral examinations with feedback, peer-led education and counseling support. After one year, sustained cessation among users was 27% in intervention schools and 14% in control schools, and the program was especially effective among users who had lacked confidence that they could quit. It did not, however, reduce initiation among nonusers. The trial is strong in design and closely matched to the county's athletes. Its effect on users who doubted their ability to quit fits social cognitive theory's emphasis on self-efficacy. Its failure to prevent initiation is instructive: an intervention built around harm and cessation did not reach the willingness-driven first use described in Module 2.

College Baseball: A Prevention Success

A companion trial in 52 California colleges tested an intervention led by athletic trainers, with a video conference for trainers and dental professionals, oral cancer screening and brief counseling for athletes and a peer-led team meeting (Gansky et al., 2005). Among 1,585 athletes, initiation over one year was 5.1% in intervention colleges and 8.4% in control colleges, a significant difference, but cessation, at about 36% in both groups, did not differ. Athletes were more likely to remain nonusers when trainers reported that the coach supported prevention. The contrast with the high school trial is striking and not fully explained; the authors suggested spillover to control colleges as one reason cessation did not differ. For the county, the finding on coach support reinforces the institutional analysis in Module 3.

The Federal Campaign: Formative Research

The Food and Drug Administration's campaign aimed at rural boys began with formative research: focus groups with 252 rural male youth aged 12 to 17 in seven states (Walker et al., 2018). The groups found that dipping was culturally ingrained, commonly encountered through close relationships and widely seen as safe, and that boys were receptive to straightforward facts from authentic messengers, especially about the progression from visible short-term effects, such as white patches in the mouth, to long-term disease. These findings closely match the county's focus groups and support the Module 4 recommendation to use concrete effects and credible messengers. The work is qualitative and does not itself test outcomes.

The Federal Campaign: Field Trial

The campaign was then evaluated in a three-year randomized field trial across 30 media markets, following 2,200 boys aged 11 to 16 living in rural areas (Farrelly et al., 2021). In treatment markets, boys aged 14 to 16 showed increased agreement with 4 of 11 campaign-targeted beliefs and attitudes compared with controls, while younger boys showed no change and the overall sample changed on only one. The design is strong for a media campaign, but the outcomes are beliefs rather than use, and the effects were modest and concentrated among older boys. The trial shows that a harm-focused campaign can shift beliefs among rural boys, not that it prevents use. A campaign in this county would need to be paired with approaches aimed at willingness and settings.

Cessation Treatment

For young men who already use, a Cochrane review of 34 trials with more than 16,000 participants provides the broadest evidence (Ebbert et al., 2015). Moderate-quality evidence from two trials suggested that varenicline increased abstinence from smokeless tobacco, and pooled trials of nicotine lozenges showed a benefit, though confidence in that estimate was low. Nicotine patch, gum and bupropion did not show clear benefits. The 17 behavioral trials were heterogeneous: some showed significant benefits and others none, and trials with telephone support had larger effects while oral examination and feedback alone did not. The review concluded that behavioral interventions may help but that it is unclear which components drive their effects. Medications require clinical involvement and are less relevant to young men under 18.

How Theory Was Used

Across these studies, theory was used unevenly. The athlete trials drew implicitly on social cognitive ideas, peer modeling, feedback and self-efficacy, but did not test theoretical mechanisms. The federal campaign's formative work is closest to a theory-informed approach to beliefs, but its evaluation measured beliefs without linking them to willingness or prototypes. None of the studies measured willingness or prototypes directly, so none can confirm that the prototype willingness model's social reaction path was changed. This is a gap for the county, whose main concern is first use.

Gaps That Matter for Nicotine Pouches

The evidence was built almost entirely on moist snuff and chewing tobacco. Nicotine pouches differ in ways that may matter: they are discreet, flavored, marketed as clean and modern and seen as safer than snuff. An updated scoping review found that the evidence on pouches is growing but consists largely of studies of use patterns, perceptions, marketing and toxicity rather than interventions (Travis et al., 2026). Messages about stained teeth and white patches may not transfer to a product without tobacco leaf. There is also no trial of workplace interventions for young men in agriculture or the oilfield, the setting where the county's older users are concentrated.

Implications for the Intervention Framework

The review supports several choices for Module 6. Team-based programs with coach support and peer leaders have trial evidence for both prevention and cessation, though not in the same study. Credible messengers and concrete consequences are supported by formative research and a field trial. Behavioral cessation support, including telephone or text follow-up, has some evidence, and medications may help older users with clinical support. What the evidence does not provide is a tested way to reduce willingness in unplanned situations, a tested pouch-specific message or a workplace model; the framework will have to build these from theory and evaluate them carefully.

Conclusion

The research on smokeless tobacco interventions for young men is modest but useful. Team interventions can raise cessation or prevent initiation, a national campaign can shift some beliefs and cessation treatment has mixed but encouraging evidence. The largest gaps, initiation driven by willingness, nicotine pouches and workplaces, are the ones most important to the county, which is why the next module's framework must combine what has been tested with what theory predicts.
