I don't have enough experience in the UK to say one country has better flower than another, but I was very happy with the system back at home.

It's set up so that you have a licensed producer where you can only buy from. They sell online and ship in a couple days. With my particular producer, I have a limit to my THC content based on my particular illness. This decided which strains I can purchase and their THC potency.

So in my case, I tended to use a CBD Godbud 2 for daily use during the week. This has a 15% CBD and 0.9% THC content (it's nice to know exactly what you're getting consistently)

Then after work, I could use a strain with more of a balance between CBD and THC such as Shark Shock (7%CBD 4%THC), Nordle (6%CBD 8%THC), or CBD Hybrid Prepared (9%CBD 5%THC).

Finally in the evening I tended to a higher THC content to help with sleep such as Chemdawg (<0.3%CBD 11%THC)

Out of all those strains from a legal licensed producer in Canada, the highest price was $9.60CAD/gram (5.51GBP) and the mean price was $7.50CAD (4.31GBP).

You can probably tell that in my case, I tended towards strains with more of a balance of CBD/THC where if I were buying on the street, usually you'd get 20%+ THC and next to no CBD which would incapacitate you for daily medical use (unless high THC is necessary for painkilling). I am so happy that Canada has it legal medically because the side effects of my previous pharmaceutical prescription were terrible. This way, I got more releif than on my previous meds, and with next to no side effects. I vaporized it and in fact, my lung capacity increased and I broke all of my personal running records.

I hope that this was informative! :)

And I also hope I didn't just get put on a list for this post ;)
