In brief: RECEPTOR ATTACHMENT

The drugs that can lead to addiction and abuse are the ones that have a very immediate effect on how you feel.
So there is a link between the drug and euphoria or sedation or relaxation etc. The quicker this happens the more potential for addiction like smoking is very rapid absorption into the bloodstream through the lungs. The effects are short lasting however and so you have to smoke again.

Dopamine stimulation is generally thought to be the necessary final pathway to addiction because this is the "reward system" of the brain. The answer to addiction is complex, really because there is no ONE single answer.
