Question by DLM: What is the current medical definition of “addiction?” (more)?
Also, does the definition differ from one substance to another, or in the case of gambling or other behaviors, where there is no chemical dependency, is there a separate definition for those as well?

I am just curious about the “umbrella” that the word addiction covers in the medical world, versus common everyday ‘people-talk’ use of the word. The more specifics you can provide, the better.

You’ll want a DSM-IV for all the definitions you’d ever care to look at.
