Yes, I don't have a link to the original article, but iirc they gave the elephant a gigantic dose compared to its body weight (the amount needed per kg of body weight goes down dramatically as body weight increases). The elephant started having what looked like seizures (faire enough, after basically eating the human equivalent of a full thimble of LSD), so they gave it a whole bunch of other drugs to try and stop the seizure. Then other things happened, so they gave it more drugs... etc.
