If I didn't have a financial interest in this, and was an impartial consumer, I might be burning mad that the government is taking away my choice to vape.
I would write to my MP and make them aware of the product and what it has done for me, and what taking away my access to it will mean. It would let them and others know it’s the position of this government agency that one can purchase a product, cigarette, which WILL kill you, but provides a large amount of revenue form them, while restricting alternatives.
Letters to the editor of your local paper, blog entries ect would go a long way.
