Pub industry leaders have raised concerns over plans to ban the use of e-cigarettes in pubs in Wales.
The Welsh government wants to make vaping in public spaces and workplaces illegal from 2017.
However, a number of industry groups believe the plans go too far and that licensees should be entitled to decide themselves whether e-cigarette usage is permitted on their premises.
The Association of Licensed Multiple Retailers pointed out that there is no evidence that vaping is harmful, the Publican's Morning Advertiser reports.
As a result, chief executive Kate Nicholls believes it is "difficult to see the logic" in banning their use outright.
She said vaping in venues should therefore "boil down to a matter of practice for the operator", as a blanket ban is "unnecessary" and "will only increase the legislative burden already being placed on pubs and bars".
Brigid Simmonds, chief executive of the British Beer & Pub Association, added that the point where "a ban is the right way forward" has not yet been reached.
She therefore argued that allowing individual pub owners to decide on the issue is the best option.
The measure has been unveiled by the Welsh government in its new Public Health Bill, which chief medical officer Dr Ruth Hussey believes will "help keep pace with emerging public health concerns".
She stated that healthcare officials in Wales want to ensure that young people living there are "able to make healthy choices throughout their lives".
Health and social services minister Mark Drakeford added that the Welsh government has a responsibility to "create the conditions which enable people to live healthy lives and avoid preventable harm to their health".
He said Wales has a strong tradition of improving public health through legislation. He is therefore confident the Public Health Bill will continue this trend.
