From the point of view of WADA, they are simply banned substances.
Someone suggested they actually define cocaine as a stimulant and not a recreational drug.
So you have a bone to pick with WADA, not me. They don't recognise your categorisation.
As I said to Tshooter elsewhere, he simply mistakes policy documents as facts.
So you and I might agree that their classification of cocaine as a PED is a mistake.
It's a mistake however that got Hingis banned for as long as Sharapova and that's the point.
They were both unfairly penalised.
Auctoritas non veritas facit legem, as the saying goes.
Neither do you seem consistent when you say Meldonium is not a PED whereas you bring in Hingis who took cocaine which is recreational and not a PED.
