In time (varying from a single use to days or weeks, depending upon lots of elements), drugs or alcohol become the only method for the person to get that exact same rush of dopamine, that same rush of pleasure, that same sense that the only way to survive is by taking more drug, more heroin, or more alcohol.
Nothing will ever replicate the experience of the very first time, however the brain becomes so distorted and connected on the drugs that the chase continues. This understanding of neuroscience has unlocked to additional insights into how dependency, as a disease, works (how to prevent drug addiction). It describes why individuals who have http://www.rehabcosts.org/center/transformations_treatment_center_inc_33484 recuperated from their addictions can still struggle with temptation or regression: not due to the fact that they are inherently bad people, but because the Rehabilitation Center parts of the brain that are accountable for dopamine production have been primed to associate anything resembling previous drug use with enjoyment.
