one would imagine that a price floor of £5 for a 2L (4.5 pints) bottle of cider wouldn't prevent many people from being able to purchase it to literally save their life. It would however, help people think twice about going through multiple of them a day?
I am usually quite sympathetic to the plight of addicts and the poor regulation and political environment around it but having lived in the UK for years ive only really heard good stuff about this. It's really not a high price point, it cuts out the really nasty stuff only.
