Background Since the passage of Proposition 99, California's comprehensive tobacco control programme has benefited from a localised policy adoption process that allows for the innovation and diffusion of strong local tobacco control policies throughout the state.
Methods The policy adoption continuum is described in the context of California's smoke-free workplace movement, and the influence of policy-driven tobacco control initiatives on social norms, behaviour and the public's health was examined.
Results The Smoke-free California policy adoption continuum reflects a general approach for policy innovation and diffusion that builds social acceptance and influences social norms, while minimising unintended consequences and creating best practices in tobacco control. California's local smoke-free workplace policies have reduced secondhand smoke exposure and supported attitude and behaviour changes. The effects of local policy adoption led to the nation's first statewide smoke-free workplace law.
Conclusions Proposition 99 created an unprecedented tobacco control infrastructure that supported local policy innovation and diffusion to influence social norms and behaviours. Tobacco control policy efforts should address campaign challenges, oppose pre-emption and confront tobacco industry influence. Advocates must be cautious of pursuing a statewide policy prematurely, as it may result in a weak and/or pre-emptive policy that can stymie local policy efforts and prolong the adoption of a meaningful statewide policy.

For over 20 years, California tobacco control advocates have employed voluntary and legislative policy processes as tools to yield long-term sustainable impacts on the health of their communities. Overall, tobacco control policies can be organised into three categories based on intent: (1) to educate individuals and influence health behaviours, (2) to create economic disincentives or (3) to regulate product production, distribution or use.1 2
Policy adoption continuum
Proposition 99 and the creation of the California Tobacco Control Program (CTCP) generated a statewide infrastructure which laid the groundwork for a localised policy adoption process that in turn has allowed for the innovation, diffusion and refinement of tobacco control policies while minimising unintended consequences.3 4 Everett M Rogers defined diffusion of innovations as ‘the process through which an innovation is communicated through certain channels over time among the members of a social system and categorises adopters of innovations into five categories: innovators, early adopters, early majority, late majority and laggards.5 The innovation and refinement of a given policy may occur across the following continuum of policy types, with varying impacts on social norms and the public's health.
Voluntary policies can be adopted by any individual or entity, and can be mandated only upon those persons who agree to be subject to the jurisdiction of the entity.6 Individuals, for example, can restrict smoking in their home, a business owner may voluntarily restrict smoking, and the owner of an apartment complex has the legal ability to voluntarily limit or prohibit smoking anywhere (including within units) on their property.7 However, voluntary policies are difficult to enforce, are generally limited in scope, are not easily tracked or measured, and do not typically have the force or effect of law.8 Despite these weaknesses, voluntary policies remain an important tool in circumstances where legislated policies are pre-empted by federal or state legislation or simply not politically feasible.
Local resolutions and ordinances
Local resolutions or ordinances may be established by any government or board authorised to set formal rules, such as a city, county, tribe, fair board, transit authority, or housing authority.6 A resolution reflects a formalised, written decision adopted by a governing body that encourages and promotes a particular action or a desired outcome. Like voluntary policies, resolutions are generally not enforceable and are limited in scope.
A local legislative ordinance is a law reflecting a mandate or directive that must be adhered to by those under the specific jurisdiction. Legislative policies are relatively easy to track and measure, and violations are typically subject to legal penalties such as fines, imprisonment, or court orders. Legislative policies are also subject to tobacco industry efforts to influence, weaken, or defeat policy adoption.9–16 Given the tobacco industry's lack of credibility within many communities, their local efforts have generally been indirect and have focused on advocating for individual rights, disputing ‘junk’ science and providing erroneous calculations of economic impacts on local businesses.13 17 18
Policy strength and iteration
The strength of a policy is dependent on a number of factors, including: restrictions, penalties, enforcement, implementation, public support, compliance and its lack of exemptions. A strong policy will include all of these factors and provide guidance regarding who may enforce the law and in what capacity.19 Compliance with a specific policy will be dependent on knowledge, social acceptance and successful policy implementation.
Using Rogers' model, the innovation and diffusion of a specific policy across jurisdictions allows for refinement or modification of the policy.5 20 This becomes an iterative process that can help build social acceptance, identify policy gaps or loopholes and strengthen protections and enforceability. While few communities fall into the innovator or early adopter categories, the rate of diffusion (policy adoption) increases as jurisdictions become increasingly more confident to modify and adopt similar or stronger policies.21 Other factors influencing policy strength and innovation include community size and political environment, as well as social and geographical proximity to other communities with similar policies.20
While the iterative process of policy adoption can occur at any level of government, the pursuit of a statewide policy should reflect best practices and establish meaningful standards that do not negate or limit future innovative local policy efforts.2 3 At the state level there is greater likelihood for tobacco industry opposition, increased scepticism regarding a policy's legal and economic impact, and the potential for pre-emption (pre-emption is the process whereby a state legislature (or Congress) takes away the right of the lesser political subdivisions to enact laws in a certain policy area).13 22 Without strong public support for a policy, a weak and/or pre-emptive policy may lead to low compliance, have minimal impact on protections and behaviour, and may stifle local policy innovation.
This paper describes the policy adoption continuum in the context of California's smoke-free workplace movement, and examines the influence of policy-driven tobacco control initiatives on social norms, behaviour and public health. While 22 other states have adopted stronger statewide smoke-free policies, California's population size (37 million), diversity (56% non-white), geographic distribution (20% rural),23 as well as the number of local jurisdictions (537),24 argues for engagement in strategic local tobacco policy work.
Moreover, California reflects the wide political diversity that can impact tobacco control policy efforts. For example, recent voting records from the 2006 ballot initiative to raise the state tax on cigarettes by $2.60 per pack indicate support from 67% of San Francisco County voters compared to only 25% of Glenn County voters.25 Additionally, there are few states that have experienced the degree to which the tobacco industry has sought to influence local and state smoke-free legislation.13 26
Smoke-free California: policies before Proposition 99
The adoption of local (city or county) smoke-free workplace policies in California began in the 1970s, when local non-smokers' rights groups13 began advocating for the specific designation of smoke-free enclosed spaces, including elevators, lobbies, conference rooms, public meetings and eventually public buildings.27 Initial smoke-free workplace policies followed the 1972 Surgeon General's Report that questioned the health risks of secondhand smoke exposure, but preceded the first significant study concerning secondhand smoke and lung cancer in 1981.28 29 Then, 5 years later, the 1986 Surgeon General's Report concluded that secondhand smoke caused disease among non-smokers.30
The strength of local smoke-free policies in California and the rate of diffusion of those policies reflected the growing scientific evidence concerning the effects of secondhand smoke exposure and the changes in public knowledge and attitudes towards smoking and secondhand smoke. While policies varied across jurisdictions, the protections generally strengthened over time.27
California smoke-free workplaces
By the time the CTCP began in 1989, over 250 workplace ordinances had already been adopted by California cities or counties.27 Concurrent with increases in programme funding and smoke-free policy initiatives, the tobacco industry presence in local California communities increased during the 1990s. From 1991 to 1992, tobacco industry spending to influence local policy efforts in California exceeded $2.4 million.31 In response to negative public attitudes towards the tobacco industry, local industry efforts were coordinated primarily through smokers' rights groups, business organisations and eventually through public affairs groups and campaign firms.13 15
The tobacco industry often targeted high profile California communities and focused on discrediting the science, potential economic impacts, implementation costs and amendments in order to weaken policies. For example, in 1987 the tobacco industry heavily opposed the smoke-free ordinance in Beverly Hills by creating the Beverly Hills Restaurant Association. Using this association the industry was able to overturn the enacted ordinance 6 months after it was adopted.13 Nevertheless, during the early 1990s, local smoke-free workplace ordinances continued to proliferate and strengthen across the state.
In June 1990, Lodi, California became the first city in the US to pass an ordinance that incorporated 100% smoke-free restaurants. And 2 months later, the City of San Louis Obispo, California, adopted the nation's first smoke-free bar law.28 As a result of local advocacy efforts and the coordination of a statewide campaign, the state of California had over 100 local smoke-free (100%) restaurant policies by 1994.28
From local to statewide policy
The first two attempts to adopt a statewide workplace policy occurred in the late 1970s, reflecting Berkeley, California's 1977 policy that created smoking and non-smoking restaurant sections.13 Following the adoption of hundreds of local smoke-free workplace policies and the passage of Proposition 99, the tobacco industry recognised the value of a pre-emptive statewide policy that could overturn current local policies and curb the impact of strong local efforts. The first industry-supported bill, Senate Bill (SB) 376, failed in 1991 once the media revealed the extent of tobacco industry involvement.13
Assembly Bill (AB) 2667 proposed the first comprehensive smoke-free workplace law in 1992, but failed after multiple amendments that included pre-emptive language that would roll back many protections established by local governments.32 When the bill was reintroduced the following year as AB 13, it was met with mixed opinions from tobacco control advocates because the pre-emptive language had not been removed. AB 13 was also countered with an industry-supported bill (AB 996), that would have allowed smoking if basic ventilation standards were met.13 32 Over the 2-year legislative session, AB 13 underwent 11 amendments and numerous attempts by the tobacco industry to weaken the provisions and create exemptions.
The 1995 enacted version of AB 13 provided for 100% smoke-free workplaces and restaurants, but allowed for a number of exemptions, including a 2-year moratorium for bars and card rooms, which was later extended to 3 years.32 Additional confusion existed regarding the inclusion of pre-emptive language in the bill. Some perceived that the law pre-empted local governments from enforcing AB 13 and enacting stronger regulations, when in reality the pre-emptive language set a minimum standard of protection, allowing for the adoption and enforcement of stronger local smoke-free policies (so-called ‘floor pre-emption’).33
The adoption of local smoke-free policies slowed considerably following the passage of AB 13 (figure 1). Although some attributed this to a chilling effect caused by the new law,22 it was more likely due to a programmatic shift of state and local tobacco control efforts to protect AB 13 and facilitate local implementation. Future innovation of local smoke-free policies focused on eliminating the exemptions in AB 13 and creating smoke-free outdoor spaces.27
California's smoke-free movement provides a context to examine the progression and influence of tobacco-related policy efforts. For the purposes of interpretation, the discussion is organised by the following four concepts: (1) policy-driven tobacco control, (2) social norm change, (3) atypical policies, and (4) emerging smoke-free outdoor policies.
Policy-driven tobacco control
CTCP funds local programmes to work on changing the environments in which people begin smoking and are able to quit, with the goal of ‘denormalising’ tobacco use. This work takes place at the community level within four priority areas: (1) eliminating secondhand smoke exposure, (2) revealing and countering tobacco industry influence, (3) reducing access to tobacco products and (4) providing cessation services.34 The social norm change paradigm demonstrates that long-term change will occur through the adoption and implementation of policies. A change in social norm typically begins with public apathy and requires an increase in public awareness in order to achieve the social concern necessary to address the problem.3 34 A strong policy should be sustainable, requiring little maintenance following implementation, allowing programmes to pursue future tobacco-related policies.
Policy strength should also be considered as a policy is refined and advanced from the local to state level. When reviewing the provisions and exemptions in local policies adopted prior to 1994, it is likely that a state law adopted in California prior to 1994 would have included greater exemptions (eg, bars) and/or pre-emption. Conversely, had more time been allowed to strengthen local policies and further increase the demand for smoke-free spaces, California may have passed a stronger statewide policy with fewer exemptions.
Over the 20 years following the passage of Proposition 99, 22 other states had adopted stronger comprehensive statewide policies without first adopting as many local policies as in California35; however, the experience of local refinement and diffusion in California has informed the policy process in other states, and reflects the strengthened evidence regarding the health effects of secondhand smoke exposure. Following the 2006 Surgeon General's report concluding that there is no safe level of exposure,36 the largest roadblock for states continues to be weak and pre-emptive statewide laws.
The strength and impact of a policy may also be minimised if the intent of the policy is unclear or influenced by competing interests. This may in turn prevent the adoption of future policies.12 For example, due to exemptions in California's statewide smoke-free workplace policy, California is precluded from acknowledgement as a smoke-free state by the Centers for Disease Control and Prevention.35 Recent attempts to remove the exemptions in the statewide law have failed. In the 2007 veto message for AB 1467, the Governor disagreed with placing further restrictions on businesses and suggested ‘increasing access to cessation services offered through the highly effective California Smokers' Helpline’ as an alternate strategy.37
Social norm change
In the social norm change paradigm, tobacco control policy is viewed as a measurable, short-term outcome.3 9 Whether policies address the price of tobacco, secondhand smoke exposure, access to tobacco, or countering the tobacco industry, the result of successful policy implementation eventually leads to intermediate outcomes, such as compliance with the policy, decreased consumption and increased quit attempts.38
In the case of smoke-free workplace policies, the refinement and diffusion of policies has helped influence reductions in involuntary secondhand smoke exposure. Figure 2 shows the cumulative number of local smoke-free policies with the reported percentage of smoke-free workplaces and non-exposure in California. From 1990 to 2005, 2-week workplace exposure rates dropped from 29% to 14%. By 2005, 95% of Californians reported having a smoke-free indoor workplace. During the same period, cigarette consumption among daily smokers declined 20% from 17.3 to 13.8 cigarettes per day, while a greater number of smokers reported considering and making quit attempts.39 Since the start of the CTCP, overall cigarette consumption in California has declined by 60.8%.40
The diffusion of smoke-free policies was also associated with changes in individual knowledge, attitudes and behaviours. In addition to the increased proportion of smoke-free workplaces, support for smoke-free restaurants grew among California smokers and non-smokers (figure 3). Further, between 1996 and 2005, the number of adults reporting a smoke-free home increased from 64% to 83% (figure 2).
Tobacco control policies have been adopted successfully at the state level without first being pursued locally. In California this typically occurs when a policy is only feasible through legislative action, or when a policy is only relevant to a particular level of government. For example, on January 1, 2008, California became the third state in the country (following Arkansas and Louisiana) to enact a smoke-free car law. Following four previous attempts in the California State Legislature, a bill was reintroduced to restrict smoking in cars where minors (under 18) are present.32 While the intent of this policy was to reduce involuntary secondhand smoke exposure, the regulation of smoking in cars at the local level was unrealistic and would likely have been unenforceable.
Emerging smoke-free policies in California
Today, smoke-free policy innovation and diffusion is occurring at the voluntary, local and state level. Given the knowledge and social demand for smoke-free spaces, local jurisdictions have begun to adopt smoke-free policies aimed at reducing secondhand smoke exposure in outdoor public spaces and multi-unit housing complexes.
Comprehensive smoke-free outdoor policies
In outdoor settings secondhand smoke can present a nuisance and a significant health hazard,41 with specific locations, such as entryways, outdoor dining areas and bus shelters having a greater risk for involuntary exposure. In response, several municipalities have found the health risks compelling enough to adopt a comprehensive outdoor policy. Currently, a comprehensive outdoor smoke-free policy is defined as one that prohibits smoking in at least five of the seven major outdoor areas: outdoor dining areas, entryways, public events, recreation areas, service areas, sidewalks and worksites.42
Following the 2006 California Air Resources Board (ARB) classification of secondhand smoke as a toxic air contaminant,43 44 Calabasas, CA became the first city to adopt and implement a comprehensive outdoor smoke-free policy. By the end of 2008, 20 California cities and counties had adopted comprehensive outdoor policies.42
Local advocates are also working to increase the number of voluntary and legislative policies that provide smoke-free living spaces. While this work is moving towards protections in private spaces, it is completely legal to restrict smoking in multi-unit housing units or buildings.7 Voluntary and local legislative policies are able to restrict smoking in residential units, on patios/balconies, and in indoor and outdoor common areas. Legislative policies may also limit or restrict grandfathering provisions, classify secondhand smoke as a nuisance and require disclosure of smoking policies to prospective tenants or buyers. By October 2008, 22 California cities had adopted local multiunit housing ordinances with cities such as Temecula, Belmont, Calabasas, Novato and Loma Linda including provisions that require the creation of smoke-free units.45
In 2008, SB 1598 was introduced to authorise landlords to prohibit smoking in residential units.32 The intent of the bill was to provide landlords with additional legal protections and encourage the adoption of local voluntary policies. The bill proposed a grandfathering provision, however, which would have significantly limited the adoption and implementation of future local voluntary policies. Following a number of amendments and opposition by major voluntary health organisations, the bill was removed from consideration.32
As California's policy adoption efforts to protect non-smokers in multiunit housing evolve, public health officials and advocates continue to focus on increasing public knowledge and acceptance of multi-unit housing policies and increasing the number and quality of protections provided at the local level. Future statewide laws should establish a minimum level of protection without pre-empting local jurisdictions from adopting stronger tobacco control policies that reduce secondhand smoke exposure in multi-unit housing complexes.
Proposition 99 created an unprecedented tobacco control infrastructure in California and provided funding for local advocacy programmes throughout the state. The programme's success is due in part to the state's ability to promulgate a strategic vision, provide training and maintain a local tobacco control infrastructure that requires accountability on the part of local health agencies and non-governmental organisations to focus on policy-driven tobacco control efforts.34
Local policy-driven campaigns have the ability to innovate and diffuse policies that support comprehensive state-level tobacco control efforts to change social norms and achieve the goal of reducing tobacco-related disease and death. Refining policies at the local level helps identify gaps in policies, minimise negative outcomes and build social acceptance. These efforts can contribute to achievement of strong, non-pre-emptive state-level policies that allow for continued local innovation and diffusion. Pursuing a state policy prematurely may result in a weak and pre-emptive policy that can stymie local policy efforts and prolong the adoption of a meaningful statewide policy.
At any given time, the number, type and strength of tobacco-related policies will vary across jurisdictions and among states. While multiple policies can be pursued simultaneously along the continuum, state and local programmes must coordinate and prioritise their efforts to maximise limited resources and maintain focus. Tobacco control programmes and advocates should proactively address the challenges to adopting and implementing policies, oppose pre-emption and confront tobacco industry influence by exposing historical and current tobacco industry practices to influence the policy process.46–48
