Spokeswoman Moira Gilchrist said: "We strongly support the recommendation for the relaxation of regulations that would allow smokers to be informed about the health benefits of alternatives to smoking such as e-cigarettes".
As part of ongoing efforts to curb the number of people who smoke cigarettes, a group of British MPs is looking to relax vaping laws.
'Concerns that e-cigarettes could be a gateway to conventional smoking, including for young non-smokers, have not materialised.
They say if e-cigarettes become more socially acceptable, less people will smoke and cause harm to themselves and others.
Vaping is less harmful than conventional smoking and the two should not be treated as the same, according to a report by the Science and Technology Committee (STC). "There is no public health rationale for doing so", said committee chairman Norman Lamb.
The report's release comes days after scientists warned that the perception that e-cigarettes are safe should be treated with caution.
- The government, the MHRA (Medicines and Healthcare products Regulatory Agency) and the e-cigarette industry should review how approval systems for stop smoking therapies could be streamlined should e-cigarette manufacturers put forward a product for medical licensing.
"The Government should carefully consider the report's recommendations, but any changes to current e-cigarette regulations should be aimed at helping smokers to quit whilst preventing young people from starting to use e-cigarettes".
"Businesses, transport providers and public places should stop viewing conventional and e-cigarettes as one and the same", he said. A long-term research project into their health impact should also be launched with updated evidence available online for health professionals and the public, the committee concluded.

Norman Lamb MP, the committee chair, said: "Smoking remains a national health crisis and the government should be considering innovative ways of reducing the smoking rate".
"E-cigarettes have already helped many smokers to quit, but they could help many more".
E-cigarettes are not covered by the smoking legislation which bans the use of cigarettes in all enclosed public and work places.
The report comes a month after Silicon Valley e-cigarette maker Juul launched its flash drive-sized vaping device in Britain, following huge success in the United States.
MPs want rules around e-cigarettes to be loosened to help smokers quit.
Approximately 2.9 million people in the United Kingdom now use e-cigarettes.
Meanwhile, NHS England's "default" policy should be that e-cigarettes are permitted on mental health units, to address the "stubbornly high" levels of smoking among people with mental health conditions, the report said.
It will review the impact of electronic cigarettes on health, their effectiveness as a stop-smoking tool and current regulations.
