BACKGROUND College campuses in the United States have begun implementing Smoke and Tobacco-Free policies to discourage the use of tobacco. Smoke and Tobacco-Free policies, however, are contingent upon effective policy enforcement. OBJECTIVE To develop an empirically-derived online tracking tool (Tracker) for crowdsourcing campus environmental reports of tobacco use and waste to support smoke and tobacco-free college policies. METHODS An exploratory sequential mixed methods approach was utilized to inform the development and evaluation of the Tracker. In October 2018, three focus groups across two California universities were conducted and themes were analyzed, guiding Tracker development. After one year of implementation, users were asked in April 2020 to complete a survey about their experience. RESULTS In the focus groups, two major themes emerged: barriers and facilitators to tool utilization. Further Tracker development was guided by focus group input to address these barriers (e.g. information, policing, and logistical concerns) and facilitators (e.g. environmental motivators, positive reinforcement). Amongst 1,163 Tracker reports, those who completed the user survey (n=316) reported the top motivations to using the tool were having a cleaner environment (79%) and health concerns (69%). CONCLUSIONS Environmental concerns, a motivator which emerged in focus groups, shaped the Tracker’s development and was cited by the majority of users surveyed as a top motivator for utilization.

BackgroundMental health units in England had to become smoke-free by law from July 2008. Concerns regarding the implementation and enforcement of smoke-free policies in these settings have been raised.AimsTo study difficulties and challenges associated with smoke-free policy implementation in English National Health Service (NHS) mental health settings.MethodQuestionnaire survey of all 72 English NHS trusts providing mental health in-patient services and facilities, supplemented by semi-structured telephone interviews at a systematic sample of 7 trusts and site visits at a convenience sample of 5 trusts.ResultsQuestionnaires were returned by 79% of the trusts, all of whom had implemented smoke-free policies. Most respondents (91%) believed that mental health settings faced particular challenges, arising from the high smoking prevalence among patients (81%), related safety risks (70%), adverse effects on the clinician–patient relationship (36%), and potential interactions with antipsychotic medication (34%). Interviews indicated that sustained policy enforcement was perceived as difficult, but that despite challenges and concerns, the impact of the policy was regarded as beneficial, with some evidence of positive behavioural changes occurring in people.ConclusionsMany mental health trusts across England have implemented comprehensive smoke-free policies but the majority state that they are facing specific difficulties. Challenges and concerns need to be explored in depth and addressed to ensure that smoke-free policies implemented under the terms of the Health Act in July 2008 are not undermined.
