No, it isn't wrong to want an apology, not at all. However, at this point, he cannot possibly give you a real apology. Why not? Because that would imply that he won't actually do any of those bad things again. He likely has not decided that he won't, particularly if he is still using, as that would mean not using again. It may one day come, but I would hope for the best and expect the worse.

PS:
I say it 'may' come because I myself have apologized, not only for things done under the influence, but also for drinking in the first place, knowing that it was dead wrong for me to do so.
