DH left the RAF, after 35yrs service, about 18mths ago. We lived in married quarters, behind the wife, for a lot of that. They absolutely never tested everyone on in one single day of CDT. They couldn’t, they wouldn’t have had the time. He was let off on one occasion because I had a very important hospital appointment that couldn’t be changed. Anyone want to tell The Scum and The Fail about that one?
DS1 is now serving. His regiment has never tested them all either. He often does the “willy watching” as they call it, so they know that the personnel aren’t using someone else’s pee.
If, and it’s a big if, Harry was allowed to skip a drugs test i would suggest he’s not the only one considering I’ve come across helicopter pilots in the armed services who have fatal car accidents while high on all sorts of things.
