My gut reaction, and vote, went on continuing to buy the juices of my choice.
I (we) have 18 months to stockpile stuff so I’ll aim to “protect” myself from the not trivial price increase for a good while.
At my current consumption level, the monthly cost will increase from two packets of fags to three. As I smoked more that a pack a day before I quit, it’s still appreciably cheaper, and far less harmful.
I await the flavour ban decisions with baited breather - the outcome of that may change my mind.
