I had an aunt die about 4 months back from Hydrocodone (Vicodin and others). She got it from accident pain clinics and was on it for years, no one knew. It basically destroyed her liver until it couldn't process anything anymore.
She had an OD one day. Not much fun watching her body just stop working. It was kind of creepy, I was at the hospital the same night she died and her skin slowly started turning yellow because of liver and kidney failure, then her heart stopped.
So yeah, I think it's addictive
