What kind of drugs are you on about? by that logic Luffy lost to Apoo.
Zoro wanted to KO Kaido permanently, yes, but he didnt that dosent mean his atack was swallow in any means of the word, and small scar? are you for real?
Look at the size of the thing, no matter how much coppium you are on, only a complete utter idiot would deny that Zoro atack by itself did way more damage than any single atack Luffy hit Kaido with. Zoro's Asura is undoubtly the highest AP atack in the raid soo far, yes, even if we take Kidd and Law's awakenings into the mix.
