Changes to how alcohol is advertised would result in the closure of small shops across Scotland, according to a leading industry figure.
Ferhan Ashiq, Scottish president of the Federation of Independent Retailers, said many convenience stores rely on alcohol sales to keep them afloat.
The Scottish Government is consulting on changes, including covering drinks behind counters - the same as cigarettes.
Regulations could also be strengthened to ban sponsorships at sporting and live events, as well as barring distillery and brewery shops from selling branded merchandise.
The consultation closes today.
Ferhan Ashiq, Scottish president of the Federation of Independent Retailers, said many stores rely heavily on alcohol sales.
'Failure waiting to happen'
He said small businesses support the government's aim to reduce problem drinking, but believes the plans are a "failure waiting to happen".
Mr Ashiq told the BBC that convenience-store owners were considering leaving the market altogether because of "heavy-handed" legislation.
As well as possible changes to alcohol advertising, small shops will be impacted by a possible restrictions on single-use vapes and by the upcoming UK ban on multi-buy deals for junk food.
Mr Ashiq said: "Margins are extremely tight. You've got to realise there are four categories that allow a convenience store to run and they happen to be alcohol, tobacco, confectionery and soft drinks.
"Without them, many convenience stores would not survive - they would be closed tomorrow.
"All that's going to lead to is increased cost for the consumer. We help reduce the costs that supermarkets will charge - if we disappear overnight, the supermarkets can charge whatever they want."
£96million cost
The Scottish Retail Consortium has said the measures would cost the retail sector £96million and would require a "complete refit of thousands of stores".
I said: "In short, these are ill-considered proposals which completely fail to recognise the work already done by retailers, the impact of the policy and provide no substantial evidence which justifies the policy."
The Scottish Government said it was meeting with a number of stakeholders.
A spokesperson added: "The function of consulting at this stage, before any proposals are finalised, is to give organisations and individuals the chance to feed back on these, and potential impacts.”
The Scottish Government said alcohol harms is one of the country's most pressing public health issues.
It aims to reduce alcohol-related hospitalisations and deaths by restricting alcohol advertising.
Drinks companies want plan abandoned
Some of the world's biggest whisky and beer companies united last month to warn the Scottish Government that its proposed ban on alcohol advertising will "destroy Scotland's drinks industry".
More than 100 drinks companies including BrewDog, Chivas Brothers, Budweiser Brewing Group, Lanson Champagne, Diageo, Whyte & Mackay and Tennent’s Lager signed an open letter to Holyrood ministers to urge them to abandon the plan, which at its most extreme would stop alcohol branding or advertising in public spaces or online.
Russell Borthwick, chief executive of Aberdeen & Grampian Chamber of Commerce, has added his backing to the drinks-sector's intervention.
He said: "When did this become a country where people are unable to make their own minds up? The proposed advertising ban is a dangerous, dystopian intervention from an administration which is becoming obsessed with pursuing snowflake policies at any economic cost.
“The anti-business positions being proposed by the Scottish Government right now are bordering on dangerous and have placed tens of thousands of jobs on the line. Our politicians need to start listening to their key industries and employers, or face losing them and the billions of pounds they generate for the Scottish economy.”
