I'm describing what an opiate addict looks like before recovery. Instead of saying "he looked like a vampire," I'd like to say something like "he looked [vampiric]."
I actually just found out vampiric was a word, but I want something that sounds better (more colloquial/natural, I suppose) and covers a variety of traits (pale, emaciated, sickly, etc).
Why I don’t just use "vampiric":
I think the idea is to find a word that isn't so "circular", and doesn't refer explicitly to vampires or require knowledge of vampires in context. If someone were to ask "What does a vampire look like?", then "It looks vampiric/vampirish" wouldn't be terribly helpful.
I don’t want to explicitly refer to drug addicts as vampires. I just want to capture those traits in the best way.
