Federal Senator David Leyonhjelm has lashed out at the Queensland government - labelling Premier Campbell Newman a "control freak" - after the government moved to make e-cigarettes privy to the same regulations as their tobacco counterparts.

The New South Wales Liberal Democrat, who proudly espouses the party's 'low taxes, less regulation, free markets, individual liberty and an end to the nanny state' mantra, said Queensland was in danger of becoming the nation's "most authoritarian state".

E-cigarettes are set to be treated the same as traditional cigarettes in Queensland.

Mr Leyonhjelm made his comments after Health Minister Lawrence Springborg introduced legislation in the Queensland Parliament which will make "vaping" as socially taboo as smoking.

Mr Springborg cited a recent World Health Organisation study that found there was "sufficient evidence" to warn 'children, adolescents and pregnant women' not to use them, and questioned whether there was enough evidence to date to prove their effectiveness as as a quit-aid.
