Most Americans want to ban smoking in all public places, but only 19 percent believe it should be illegal in the U.S., according to a poll by Gallup published on Friday.
The polling firm in Princeton, New Jersey, did a telephone survey between July and 10 July, which began performing in 2001, and 59 percent of respondents approved of the ban on snuff in public places.
10 years ago was for 39 percent, an amount similar to that of 2007, according to a survey published on the website www.gallup.com.
19 percent of respondents who wanted to legislate against the snuff is about 14 percent in 1990 wanted that smoking was illegal.
"The majority of Americans now support a total ban smoking in public places, establishing a significant change from four years ago, the last time that Gallup conducted a survey on this issue," the firm said.
"Relatively few Americans support the idea that smoking is illegal in the country, perhaps in part because of practical difficulties that would result in compliance with this ban."
The anti-snuff in the U.S. has increased in recent years.
In New York, the city's most populous country with 8 million people, smoking is prohibited in most public places, including outdoor plazas and beaches. The District of Columbia and 27 states have passed laws against snuff.
Gallup reported that in its July survey also asked Americans about their habits on snuff.
"The 22 percent of American adults admitted smoking in the last week, a percentage that has not changed substantially over the past five years," said Gallup.
The survey results are based on a random sample of 1,016 people over 18 years in 50 states and the District of Columbia. Gallup said that the maximum margin of error was plus or minus 4 percent.
