To be honest the small piece done by Sky some time ago was a lot more positive in my opinion. I also read this week the BMA have come out very positively in favour of vaping too. I will watch Sundays show in the hope that it presents facts rather than beliefs and in saying that I realise that no one knows for certain that vaping is 100% safe, but I feel as a non nicotine vaper that I would consider introducing nicotine if it was proved to help with Alzheimer's and dementia.
