Why is heroin so addictive? When heroin enter the body it heads straight for the users brain. Once there it takes over the parts of the brain that are responsible for “reward” and addiction.
Heroin will trick a users brain into stopping the production of reward feelings on its own. When a user stops taking heroin they do not have any good feelings; their brain is no longer producing “reward” feelings so heroin use was the only way of achieving it.
