The anti-smoking lobby group, ASH Ireland, has accused those opposed to the ban on smoking in the workplace of making "ridiculous" arguments against the measure.
The group also called on the Government to increase taxation on cigarettes, saying there should be a means of minimising the impact on inflation of such increases.
The group's chairman, Prof Luke Clancy, said: "ASH Ireland is entirely confident that the workplace smoking ban will be successful despite many ridiculous predictions from elsewhere. Most people obey the law, and all employers, including the vintners, have a responsibility to ensure the law is upheld where possible."
Publishing ASH Ireland's annual survey, the professor said he hoped t many people would use the support of the anti-smoking legislation to insist on a smoke-free environment in the workplace.
"This desire of members of the public to insist on a smoke-free environment did manifest itself after similar bans were introduced in a number of states in the United States. Next year we urge people, especially workers, to insist on their right to a smoke-free environment."
He said the group was concerned that recent price increases in tobacco products were not in line with the stated policy of the Government to create a "smoke-free society".
"Price increase is well established as the most effective means of persuading smokers to quit and encouraging young people not to experiment with tobacco.
"The Government must find a mechanism which deals with the inflation fears and clears the way for significant price increases on tobacco products in the coming years."
Prof Clancy also expressed concern about tobacco advertising on Formula One motor racing cars, which he said was unacceptable given the Government's ban on cigarette advertising.
"ASH Ireland is deeply concerned about the major promotion and advertising of tobacco products on RTÉ via the broadcast of Formula One motor racing.
"During the broadcast of Formula One events a tobacco product is being advertised virtually every second," the professor said.
