A lot of substances cause withdrawals/dependence and act of brain chemistry, e.g., the vast array of psychiatric drugs. However, I have never seen the word addiction used in the context of antidepressants, mood stabilizers, etc.. Even non-psychiatric drugs like NSAIDs, insulin, hypertension medication, etc. can have a withdrawal effect. I might be mistaken, but I am under the impression that addiction is psychological in nature. Take gambling addiction, for example, I am not certain if there is any physical withdrawal effect, but there is definitely a psychological compulsion.
