If you get the good stuff (you can choose, you just need to do 5 min research) then absolutely. Much stronger.

There's medical weed grown outdoors in Portugal which is cheap but worse than any decent black market stuff.

Impossible to go wrong with anything cultivated in Canada though.

I'm writing a long form note post about my experience getting prescribed in the UK. It's much easier than you might think but it does cost money because the NHS refuses to cover it so far.
