Hero
It's worth noting that cocaine does not cause physiological dependence or withdrawal and its addiction is purely psychological in nature. It's a very dangerous drug, but not for the same reasons as, say, alcohol or heroin. Addictiveness does not equate to the potential for harm.
Obviously oreos are less dangerous.
I'm finding conflicting information about whether cocaine (I looked up heroin, too) is physically addictive.
Lots of references describe it as physically addictive, although, in the sense of the "body getting used to it's presence". I presume there are other more definite physical dependencies, with a more concrete physiological effect, that is meant.
Ok, did some more searching, and it seems that some sites are too loosely using the term "physical dependence". The more detailed sites (e.g., http://en.wikipedia.org/wiki/Substance_dependence, http://en.wikipedia.org/wiki/Physical_dependence, and http://www.nlm.nih.gov/medlineplus/ency/article/001522.htm) do a much better job.
I suspect a part of the fuzziness is because the definition will affect diagnosis codes, with a direct link to heath care and insurance issues. Lots of vested interests pushing the definition one way or another.
Thx!
