In the first day or two of Navy nuclear power school in 1974, all of us junior officers in the new class (93 of us IIRC) were assembled in an auditorium for a don't-do-drugs lecture by a chief petty officer who was a "fleet sailor" — i.e., he'd been around the block a few times, so it was thought that young sailors would pay more attention to him — and had been assigned to get trained as the drug counselor.

The speaker made one especially-memorable comment: "I'm told that shooting heroin feels like an all-over-body sexual climax. I don't know about you, but to me that sounds pretty neat."

(The rest of the lecture was standard stuff about how doing drugs would get us de-nuked and basically end our careers.)
