Talking of medicines, let's just run through some of the consequences. And I think I'm qualified to talk on this.
1. You think that drugs are expensive? Think again, they make up less than 10% of the NHS bill. And the reason they're cheap is that EU freedom of trade makes it harder to 'grey trade', i.e. buy cheaply in one country and then sell in another at a high price, effectively bet against patients. And EU legislation made it possible for cheaper generic medicines to bring down the cost of drugs.
2. One of the nasty, intrusive EU laws you don't like is the Falsified Medicines Directive, which is making it easier to trace medicines across Europe and make it much, much harder to pass on fake or poor-quality medicines to the patient. As this will no longer apply to the UK, look forward to a choice of either accepting the EU approach anyway, or getting medicines counterfeiters to see the UK as the easiest market to sell their 'wares' to.
3. Do you yearn for new treatments, better and advanced medicines? Sorry. One of the biggest problems in introducing a new medicine used to be that you had to prove to every single country that the medicine was safe, created an advance in treatment etc. Under the EU that has been replaced by the so-called 'CP', the Centralised Procedure, and the science only has to be proved once at EU level before it is released to patients. That will now have to be done twice, once for Europe and once for the UK - and it's a long, complex procedure as it rightly should be. So if the disease doesn't have many patients so no mega-millions coming in, how sure are you that the inventor will be bothered with the UK with a smaller number of patients?
Every sinew in my body says that the people who voted for this are the ones who will be hurt the most.
