When I was part of the recruiting system for the RAF, a number of "make or break" questions were asked of potential recruits. One of them involved the taking of drugs. A positive answer would disbar the application going any further. He knew exactly what the penalty would be for possession and taking of a Class A drug. As a senior officer he held a position of higher responsibility in any case and it appears that rather than discouraging the use of cocaine, he had condoned and even encouraged its use in those junior to him.
