Lets wait and see what impact these proposed fines for retailers will do. They'll never eradicate all the black market stuff but if they scare off enough small retailers it'll knock a flipping great hole in it.
I must admit it seems so ludicrase and laughable that they want to try to get people off tobacco by restricting them to things that taste like tobacco. What genius decided that was a good idea? Since I gave up the rollies one thing I specifically made a point of never doing was vaping any tobacco flavoured juices.
