Heroine is a very quick acting drug. Not as quick as cocaine, for instance. But one always tries to get at it by saying "what's the half life of it?", "How long of a time does it take until there is only half left?" Basically Heroine will last 6-8 hours and then you're done. You have broken down what was in your body and you need more if you pursue the effects.
