Q. Why do people become dependent on alcohol?
I did a search in Academic Search Premier and the CINAHL databases. I used the following searchterms:Alcoholism and "risk factors" / Alcoholism and Treatment / Alcoholism and genetics. Quite a few scholarly journals came up in these databases.
CQ Researcher (found under C on our database page) has a report from June 2012 that discusses alcohol abuse.
Please give the above databases a try and if you run into problems please feel free to stop by the reference desk.
