Cigarettes are no longer allowed to be displayed in large stores across Scotland.
The legislation came into force on Monday and is part of a Scottish government initiative to reduce the number of smokers to less than 5% by 2034.
Large stores such as supermarkets will be affected although most shops have had a blank display in place for the past few weeks in preparation for the new law.
The ban was set out in the Tobacco and Primary Medical Services (Scotland) Act 2010, which will also see the sale of cigarettes from vending machines prohibited.
Minister for Public Health, Michael Matheson, said: “These bans are the right step to prevent young people in Scotland from taking up smoking. Each year, tobacco use is associated with over 13,000 deaths and 56,000 hospital admissions in Scotland.
“That is why it is so important that this Government works to improve health by reducing the number of people who choose to smoke and evidence shows that young people exposed to the promotion of tobacco are more likely to try smoking.”
Smaller shops such as newsagents and petrol stations won’t be affected until April 2015.
