Narcosis

Becoming unconscious/asleep because of the effects of a narcotic/opioid drug.

Joe: Damn Jim, took 20mgs of Morphine last night and 5 minutes later I was out for 8 hours.
Jim: You had narcosis Joe. Taper the dose down to 15mg, you should be okay then.

Endorphins 

Your body's natural pain reliever, released when stress or pain levels are high, or after an orgasm.
Equivalent to a narcotic pain reliever once released.

I went for a run and got the Runner's High (endorphins), it felt great.
