According to a US government report released on Thursday, the decline in smoking in the United States may continue to stagnate, while the use of e-cigarettes by adults seems to be on the rise, according to foreign reports.
Last year, about 14 percent of U.S. adults were smokers, the third year in a row that the annual survey found. But health officials say the change in methodology makes it difficult to compare it with the 14% reported in 2017 and 2018.
The latest decline in adult smoking was in 2017, up from 16% the previous year.
According to the latest data from the Centers for Disease Control and prevention, there are more than 34 million adult smokers in the United States.
At the same time, about 4.5% of adults were considered current e-cigarette users last year, about 11 million.
The ratio appears to have risen from 3.2% in 2018 and 2.8% in 2017. However, officials again said it was difficult to compare 2019 with previous years due to changes in the survey.
CDC's data are based on feedback from about 32000 people.
Health officials have long argued that tobacco use is the main cause of preventable diseases and deaths in the country.
