The OP's video showing Lord Forsyth 'seeing' the benefits of vaping with his son is a positive thing to see, even if it had no lasting effect on the bill at the moment. The more recent studies (e.g. testing of the air in a small vape shop showing NO detectable horrors in the vapour) along with the realistic long-term testing of vaping on the human body may provide some more support for future changes.
Until the knee-jerk, short-sighted, badly-researched, profit-driven changes we have in place now are brought under the spotlight again collecting the evidence from scientific research and helping the general public see the real benefits of vaping are what we have to do. Fighting the bad-press with facts, correcting the mis-information with real studies, and just politely correcting the scaremongering tabloid nonsense reactions without wanting to do harm to the idiot mouth behind them.
The 'hammer' of facts is getting bigger quickly so the 'nail' of stupidity can be hit with some clout in the future. At the moment we are suffering an 'angry mob with torches and pitchforks' and very little information but incorrect biased tabloid headlines supporting their arguments.
