E-cigarette Use in Veterans Seeking Mental Health and/or Substance Use Services

Abstract

abstractObjective: Individuals with mental illness and substance use disorders smoke at elevated rates and tend to have greater difficulty quitting smoking as compared to the general population. Some believe that e-cigarettes may reduce harm associated with smoking, but little is known about e-cigarette use, perceptions, and motivations for their use among individuals with mental health and/or substance use disorders. Methods: Rates and correlates of e-cigarette use, perceptions, and sources of information about e-cigarettes among smokers seeking mental health and/or substance use services (N = 188) at the VA Connecticut Healthcare System were assessed via a brief survey. The Pearson χ2 test of independence was used to compare veterans who currently used e-cigarettes with those who did not. Logistic regression was used to examine independent attitudinal differences controlling for potentially confounding variables. Results: Participants were generally male (90%), Caucasian (54%), and older than 50 (69%), with high rates of at least one mental health condition (82%), at least one substance use disorder (73%), and comorbid mental health and substance use disorders (55%). A relatively high proportion of the sample (30.9%) used e-cigarettes. These participants, compared to those who did not use e-cigarettes, were more likely to have a mental health disorder and less likely to have a substance use disorder, started smoking later in life, spent less money on smoking, and were more likely to have tried to quit “cold turkey.” Knowledge of e-cigarettes originated most often from TV, radio, or personal contacts. Respondents held generally positive perceptions and motivations regarding e-cigarette use (i.e., it is socially acceptable, may help reduce/quit smoking, less harmful to others). Despite positive attributions, rates of dual use of e-cigarettes and traditional cigarettes was high (86.2%), and very few people using e-cigarettes (6.9%) indicated that e-cigarettes actually helped them quit smoking, suggesting little related harm reduction. Conclusions: E-cigarettes are commonly used by smokers with mental health conditions and/or substance use disorders, a high-risk group that feels positive about e-cigarettes. However, positive regard of e-cigarettes did not appear to translate to ability to reduce or quit cigarette smoking. Safety and effectiveness research on e-cigarettes is urgently needed.
