Heroin is able to cross the blood-brain barrier more quickly than morphine, which allows it to produce a more intense and immediate rush of euphoria. Despite having a lower potency, the quicker onset of effects makes it a more addictive drug. Additionally, heroin is metabolized more quickly than morphine, leading to a shorter duration of action.
