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.
