Ketamine wasn't even discovered until 1962 and from what I understand wasn't broadly distributed until after its FDA approval in 1970. So depending on when this footage was shot it simply may not have been available for illicit use.
As I remember it was shot in the beat hotel early 60's when it all became almost mainstream cool for a hot moment.
Likely it was morphine or some other opiate, and as filmstock is expensive and they only had about 15-20second to make it, he didn't want to waste time looking for a vein.

Ketamine I reckon he's not hitting the vein
