I thank the witnesses for their excellent presentation. Professor Stockwell presented very dense material in a very succinct manner. According to one of the slides, which related to the potential effectiveness of the different types of minimum pricing, setting a price per unit of alcohol is a more effective approach than setting a price per litre of alcohol. I ask Professor Stockwell to elaborate. Is evidence available to show minimum pricing per unit is more effective in reducing consumption and the potential for criminal behaviour? For how long has this approach been in place in Scotland and elsewhere?
