The Health Secretary Shona Robison said: “the measure is to tackle the devastation caused by cheap, high-strength alcohol.”
The retailers should now make sure a unit of alcohol costs at least 50p.
The cheapest bottle of red wine (9.4 units of alcohol) now costs £4.69, while two litres of 5% cider cost £5.
While the new measure has doubled the price of cider and larger, it leaves more expensive drinks unaffected.
The new law is therefore unlikely to impact on sales in pubs and clubs but it will help to cut deaths as the number of people losing their lives due to alcohol related illnesses in Scotland is nearly double than the rest of the UK each year.
The first Minister Nicola Sturgeon said: “We have a real problem with our relationship with alcohol in Scotland” and “the new law should save lives.”
Deaths related to alcohol illness cost £3bn annually to the government, twenty-two people die from alcohol each week in Scotland.
Critics who do not appreciate the new minimum pricing alcohol law argue it will affect less fortunate, and alcoholic will still find an alternative way to get money for their drink.
However, some campaigners hope England will replicate Scotland’s new law as it could save more than 1,000 lives.
It is now illegal to sell alcohol for less than 50p per unit in Scotland and posters in shops this morning could tell how aware the retailers were.
