where can I buy absinthe in the UK

I’ve been trying to find a bottle of ” cannabis absinthe Antonio Nadal 80″ however most places that sell it don’t ship to the UK and I know its legal here. I was served this at a pub and I quite enjoyed it since its pretty strong and I’m sure if I bought a bottle I could make it last at home. Just need to find a place that sells it, lady at the pub said she doesent remember where they got it from.
