Background

This study examined the impact of a tobacco-free grounds (TFG) policy and the California $2.00/pack tobacco tax increase on tobacco use among individuals in residential substance use disorder (SUD) treatment.

Methods

We conducted three cross-sectional surveys of clients enrolled in three residential SUD treatment programs. Wave 1 (Pre-TFG) included 190 clients, wave 2 (post-TFG and pre-tax increase) included 200 clients, and wave 3 (post-tax increase) included 201 clients. Demographic and tobacco-use characteristics were first compared between waves using bivariate comparisons. Regression models were used to compare each outcome with survey wave as the predictor, while adjusting for demographic characteristics and nesting of participants within programs.

Results

Odds of clients being current smokers was lower (AOR = 0.43, 95%CI = 0.30,0.60) after implementation of TFG compared to baseline. Adjusted mean ratio (AMR) for cigarettes per day was lower post-TFG compared to baseline (AMR = 0.70, CI = 0.59, 0.83). There were no differences, across waves, in tobacco-related knowledge, attitudes, or services received by program clients, or use of nicotine replacement therapy. Increased cigarette taxation was not associated with reductions in client smoking.

Conclusion

Implementation of a TFG policy was associated with a lower prevalence of client smoking among individuals in residential SUD treatment. Increased state cigarette excise taxes were not associated with a further reduction in client smoking in the presence of TFG policies, though this may have been confounded by relaxing of the TFG policy. SUD treatment programs should promote TFG policies and increase tobacco cessation services for clients.

Objective

This study assessed whether exposure to cigarette graphic warning labels (GWLs) increased attendance to a smoking cessation programme.

Method

From 2014 to 2016, alternating cohorts of smokers in 3 residential drug treatment programmes received either GWLs (experimental) or transparent (control) labels placed on their cigarette packs for 30 days. The primary outcome was the proportion of participants who chose to attend a smoking cessation group after the labelling period.

Results

The sample (N=601) was 72.6% male, with a mean age of 41.9 (SD=11.16) and included African-American (37%), White (29.4%) and Hispanic (19.6%) participants. While similar on most measures, controls were more likely to be married, had been in the treatment programme longer and registered higher on expired carbon monoxide (CO). After labelling, the proportion attending at least one cessation group was 26% in the experimental condition and 18.8% among controls. In an intent-to-treat analysis adjusting for group differences at baseline, and for 2 levels of nesting, those who received GWLs were more likely than controls to attend the smoking cessation group (OR=1.58, 95% CI 1.02 to 2.44).

Conclusions

Smokers who received GWLs on their cigarette packs were more likely to attend a cessation programme. Thus, this study is one of the first to document a change in a directly observed behavioural outcome as a function of month-long exposure to cigarette pack GWLs.
