30 million U.S. adults have used e-cigarettes, unpublicized CDC data reveals
This was the first time the NHIS, the main source for national smoking prevalence statistics, asked about e-cigarettes. The survey asked participants if they had ever used e-cigs, even one time; if they had, a second question asked them if they currently used them every day, some days or not at all (“triers”). From this data, I have produced the first-ever national estimates of e-cigarette use.
About 71 percent of e-cigarette users are also current smokers (every day or some days), and 22 percent are former smokers. The rest (about 7 percent or 595,000) were never cigarette smokers, but nearly 70 percent of them said they smoke products other than cigarettes (cigars, pipes, water pipes or hookahs, very small cigars that look like cigarettes, bidis or cigarillos) every day, some days or rarely.
Of the 6.3 million smokers who used e-cigarettes, only 22 percent used them every day. In contrast, among the nearly 2 million former smokers who used e-cigarettes, about 63 percent – or 1.25 million – were daily users. Among those who never smoked cigarettes, but did vape, only 16 percent were daily users.
Among daily smokers, there was virtually no difference in cigarette consumption; regardless of whether they vaped or not, daily smokers consumed 14-15 cigarettes per day on average. Cigarette consumption was more variable among “some day” smokers: those who used e-cigarettes every day smoked only 3.5 cigarettes on the days they smoked, while those who used e-cigs on some days smoked 5.2 cigarettes. Some-day smokers who had tried e-cigarettes consumed 7.8 cigarettes per day, while those who had never used an e-cig smoked 5.6 cigarettes.
While it is encouraging that almost 2 million former smokers were currently using e-cigarettes in 2014, it is not possible to prove that they had used e-cigarettes to quit. However, 85 percent of these former smokers had quit five years or less before the survey, making it plausible that e-cigarettes played some role in their becoming or staying smoke-free.
The table below compares some characteristics of former smokers who currently used e-cigarettes with former smokers who never used them. (These comparisons are general observations that might change after additional analysis). Former smokers who used e-cigarettes were younger and more likely to live in the South; they looked more frequently for health information on the Internet during the previous 12 months.
|Former smokers who use e-cigarettes and those who never use them|
|Characteristic||Current users||Never used|
|Under age 45||59 percent||22 percent|
|Live in the South||46 percent||36 percent|
|Live in the Northeast||9 percent||19 percent|
|Looked for health info/ Internet||62 percent||44 percent|
|Quit smoking less than five years prior||85 percent||15 percent|
Another statistic stands out: In 2014, the percentage of adults in the U.S. who smoked was 16.7 percent, down from 17.8% in 2013.
Cigarette smoking in the U.S. continues an inexorable decline. Rather than impeding progress, e-cigarettes may be accelerating a smoke-free revolution.
