Most ASDA stores I've been to had their Accessible toilet door open outwards. I think I only remember one store that had the door open inwards but thats about it. I used to like the antidrug lighting but looking back, it just seems pointless as it does come with drawbacks. I've never experienced antidrug lighting before so I cant really be certain.
Every ASDA I've been to except for Lowestoft has had the accessible toilet's door open inwards. There physically isn't space at most of them, although they could get away with an outwards one at Yarmouth
The door opening inwards reminds me of like a hospital toilet if you get what I mean. Also you can see that this light is on full blast like you mentioned, imagine if someone disabled spent 10 minutes in here god knows what would happen.
