Sir,
It is said that he found a more satisfying 'high'.
Do the annual military aviator physicals include drug tests for coke?

Depends what time period you are asking about.
Today the answer would be yes.
In the early 70's it depends apparently.

Actually the answer today and for the past 15 years (in my case) has
been no. I've never been drug tested at a flight physical. I've been
randomly drug tested several (probably 20+) times in my career but
again never at a physical.
