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.

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.
