He added that the decision was also based on international studies that highlighted the dangers of using such items.
The UAE's original 'sin tax', which first came into effect in October 2017, included cigarettes and other tobacco products as well as energy drinks and carbonated beverages- but the scheme was later expanded by the federal cabinet.
