Answer:
It like a Drug addiction, drug addiction is a brain disease. Every type of drug of abuse has its own individual mechanism for changing how the brain functions. But regardless of which drug a person is addicted to, many of the effects it has on the brain are similar: they range from changes in the molecules and cells that make up the brain, to mood changes, to changes in memory processes and in such motor skills as walking and talking.
There is no "one size fits all" form of drug treatment, much less a magic bullet that suddenly will cure addiction. Different people have different drug abuse-related problems. And they respond very differently to similar forms of treatment, even when they're abusing the same drug. As a result, drug addicts need an array of treatments and services tailored to address their unique needs.
