According to a BBC News article brain scans have revealed "a possible biological basis for cocaine addiction".
Next week: brain scans reveal 'possible' biological basis for thoughts, feelings, actions and neurological illness.
Most pop science articles starting with "Brain scans reveal..." are usually uninformative. This one is no exception.
You're selling the article a bit short though. The main idea seems to be that the reason why addiction likelihood varies between people seem now to be better understood, or so do the researchers think. Not that article gives much insight into that, beyond "In effect, the drug messes with what is colloquially known as willpower - with some maybe more vulnerable than others." Yawn.
One of the possible solutions to the problem of media reports on scientific discoveries with its poor language and concepts borrowed from popular culture and fiction, is to require sceintific qualification to any journalist, or create an hybrid: an intermediate journalist and scientist carrer in universities and faculties.
