And the pricing for that is open. The NHS pays £3.31 for a Salbutamol inhaler with 200 doses[0]. They are paying private dispensaries (high street chemists, etc) to handle the prescriptions and drugs and whatnot. I still think the prescription price is well worth the cost.

They also get Humalog much cheaper[1]. £29.46 vs $240.18

There's no sane way you can see discrepancies like this and not see something untoward happening.
