Potential problems with e-cigarettes

•Possible gateway for nonsmokers to cigarettes

•Not safe—▫“Water vapor”▫Not all use good product manufacturing

processes▫Calls to poison centers are up

•Could delay or prevent quitting among smokers—end up with dual use

Why consider e-cigarettes?

•E-cigarettes have the potential to act as a nicotine replacement therapy▫Could help individuals quit cigarettes▫Broader appeal = greater reach▫Potential population impact?

•There is no product likely to be deadlier than cigarettes▫Orders of magnitude▫Looking for “game changer”

Most Important reason?

•Credibility

Why consider the behavioral health population in this discussion?•High rates of smoking•Both greater uptake and less cessation•High rates of morbidity and mortality

from smoking•A tobacco disparity population

▫Important that regulations not result in disproportionate harm

Tobacco control among those with behavioral health conditions•Many myths around quitting•Excluded from much of the research•Changing

▫Smoke-free policies in facilities▫Recommendation of greater assistance▫Recognition

Need to quit Want to quit Can quit

E-cigarettes and behavioral health•It’s already happening•High consumers of cigarettes•E-cigarettes are most salient to smokers•Bring data to bear

A way to view e-cigarettes•Perceptions from clinicians—what would

you do if someone wanted to quit using e-cigarettes?▫Physicians▫Paraprofessional cessation counselors

•Data from a national probability survey▫Focus on those with Mental Health

Conditions•Clinical practice implications

Methods•Family Physicians (N=21) from Family

Medicine Department at the UCSD School of Medicine

•Cessation counselors (N=57)

Summary of Perceptions

•E-cigarettes are relevant•See them as higher in health risks than

NRT or varenicline•See them as not very effective• Important to clinicians that FDA has not

approved them as quit aid•With little data to go on, they are erring on

the side of being against e-cigarettes▫Treat like cigarettes—taxes, advertising,

youth access, use in smoking-restricted areas

Likely answer?

•If a smoker wanted to quit smoking by using e-cigarettes, what would you do?▫Most would discourage him from using

e-cigarettes to quit smoking▫Offer alternative to e-cigarettes such as

NRT, bupropion, varenicline▫Recommend and provide or refer to

behavioral cessation counseling

What if…?

•The patient had tried and been unsuccessful with all the recommended pharmacotherapies (as is true of many with behavioral health issues)?

•Insisted that he would only try to quit if he could use e-cigarettes?

•Was unwilling to give up smoking at all, but was willing to switch to e-cigarettes?

Then need to consider the likely impact of e-cigarettes?•Need to weigh:

▫Potential to prompt a quit attempt▫Ongoing nicotine addiction▫Potential to delay quitting cigarettes

Mental Health Conditions•High smoking prevalence•More difficulty quitting•Use of other tobacco products not known•E-cigarettes

▫Do they use them?▫If so, why?▫Are they likely to use them in the future?

Implications

•Beneficial? ▫Decrease cigarettes▫Increase quitting

•Detrimental?▫Maintain smoking▫Delay quitting

•Tobacco Control Policy▫Accessibility▫Pricing▫Advertising

Methods•Conducted through GfK’s Knowledge

Panel•National probability sample (N=10,041)•Asked about diagnosis of Anxiety

Disorder, Depression, or “Other Mental Health Condition”
