Scottish Labour has called for legal limits on the amount of caffeine in alcoholic drinks such as Buckfast.
The party’s call came ahead of the launch of its alcohol commission, which aims to find ways to tackle Scotland’s record of drink-related violence.
Labour has opposed Scottish government plans for a minimum price per unit of alcohol but said its commission would be allowed to consider the move.
Ministers said the Labour move showed “blatant disregard” for parliament.
The alcohol commission, being chaired by education expert Prof Sally Brown, will be asked to consider how much caffeine should be allowed in drinks.
Caffeine is a psychoactive stimulant.
Strathclyde Police recently told BBC Scotland that Buckfast, a fortified wine with a high caffeine content, was mentioned in 5,000 crime reports over three years.
Scottish Labour said Buckfast contained 281mg per 750ml bottle – as much as eight cans of cola, while Red Square Reloaded contained 420mg per litre).
Labour pointed to the 150mg per litre limit set in Denmark, Iceland and Norway.
Scottish Labour health spokeswoman Jackie Baillie said: “I believe the risks involved in consuming caffeinated alcohol are so great that the Scottish government must take action.
“The research suggests you are more likely to end up in hospital or be assaulted if you drink these products.”
The commission’s membership also includes Sam Galbraith, a former Labour minister for health in Scotland, Graeme Pearson, former head of the Scottish Crime and Drug Enforcement Agency and Glasgow licensing board convener Stephen Dornan.
The commission, which will also look at the enforcement of existing laws, aims to influence the government’s Alcohol Bill, with a report due in the summer.
It is also expected to consider issues arising from the use of caffeinated soft drinks as mixers.
Ms Baillie reiterated Labour’s position on minimum pricing – a policy which has encountered strong opposition support.
She said: “The [Scottish Parliament's] health and sport committee will be looking in detail at those arguments – should the commission wish to look at that I’m not going to be stopping them – but frankly the bulk of it will be on alternative pricing mechanisms.”

The judge has now agreed that the owner must return to prison pending a new trial – expected by the end of the year – and should have left the police.

Lebanese search teams have retrieved a flight recorder from the Ethiopian Airlines jet that crashed in the Mediterranean, army sources say.

Local authorities in England could lose many of their planning powers regarding schools if the Conservatives win the general election.
A draft of the party’s planning policy, seen by BBC One’s The Politics Show, says the schools secretary would take decisions on building new schools.
They would, in effect, be treated like major infrastructure projects.
The policy says the party would not want unnecessary bureaucracy to stifle the creation of new community schools.
The Conservative policy on planning, to be published later this month, is based on the idea of localism – bringing an end to national targets and giving freedom for local authorities to decide how much housing or commercial development they want in their area.
But schools will be the exception to the rule, according to the latest draft of the document.
The party has pledged to allow parents and non-profit making organisations to set up new, independent schools wherever they want.
The Conservatives’ planning system would remove potential obstacles to the development of new schools by curtailing the power of local authorities in this area, according to the document.
The leaked planning policy says “for the [education] policy to be successful it is essential that unnecessary bureaucracy is not permitted to stifle the creation of new community schools”.
Under the policy, as well as planning decisions on new schools being taken by the secretary of state for children, schools and families, anyone would be able to turn an existing building into a school without the need for planning permission.
And when an existing school closed, that land would not be allowed to be used for any other purpose without the agreement of the schools secretary.
Shadow planning minister Bob Neill told The Politics Show said the party had made it clear it wanted to help parents and communities establish new schools.
He said: “That’s our national policy and naturally therefore we, within the planning side of things, want to facilitate that approach.
