They already are... Some parts of Ketamine have been altered or omitted (I'm not sure of the process) but it 'becomes' esketamine- I don't have all of the answers, but... it has literally saved my life. i never thought I could or would feel normal again- much less feel joy again after my two year old son passed away. Sounds like you may not have all the answers. It hasn't dumbed me down- and I've never done ketamine- other than my treatments- it has quite literally woken up my heart and spirit again and I am so grateful... They aren't saying go score drugs off the street and you won't be depressed anymore... But I assure you- they are certainly onto something... Also, Many soldiers with PTSD have been helped, as well... It isn't as simple as you are thinking it is.
