Iowa: Research Finds Some State Laws Linked to Lower E-cigarette Usage

State laws that regulate e-cigarette sales and usage may lower their use in states where those laws have been implemented, according to a new observational study from the University of Iowa published this week by the journal JAMA Network Open.

In the observational study, a research team led by Dr. Wei Bao, assistant professor of epidemiology in the University of Iowa College of Public Health, estimated the potential impact of five laws on e-cigarettes use by adults in the United States. Some of those five laws are implemented in many states, such as prohibitions of self-service displays of e-cigarettes at retail outlets, which was in force in 26 states. Others, such as age limitations or a tax, were in force in just a few states.

After linking e-cigarette use information to state laws based on the participants’ states of residence, the study found that differing laws had different impacts.

People were 14 percent less likely to use e-cigarettes in states where laws prohibited their sale to persons under age 21. This is also the law that is in force in the fewest number of states — only California, Hawaii, and the District of Columbia have implemented age restrictions. However, a new rule from the U.S. Food and Drug Administration now makes it illegal to sell e-cigarettes to anyone under the age of 21 in the U.S.

Dr. Bao’s study, “Association of Electronic Cigarette Regulations with Electronic Cigarette Use Among Adults in the United States,” was co-authored by Ms. Yang Du, Dr. Buyun Liu, Ms. Guifeng Xu, Dr. Shuang Rong, Dr. Yangbo Sun, Ms. Yuxiao Wu, Drs. Linda G. Snetselaar, and Robert B. Wallace, all of the University of Iowa. It was published in the January 31 issue of JAMA Network Open.
