At least that last point is starting to change. It's not something that a GP could prescribed, but hospital specialists can prescribe medical cannabis for a select list of conditions.  You might remember there was that epileptic boy who had his meds from the US confiscated, and finally got a special exemption from the Home Secretary to have it shipped to his hospital. That was a big milestone towards CBD being reclassified as a medicine in 2017.

Yep, painfully painfully slowly. But it is happening, I have a feeling we need another economic collapse (much worse than the past 10 years have been), or Labour or the LibDems growing a backbone, decent leadership and actually pledging to do it (and not just talk about it in parliament and say no as they do a line of coke) before we get actual medical cannabis or one day the dream of legalization.
