Brief Answer:
Some information:

Detailed Answer:
The information I have is that morphine is a metabolite of codeine, and it looks like it is also in the breakdown of hydrocodone (see link in response above).

What I would suggest is this: close this current discussion with me (I am a family practice doctor) and repost it with the following words in the first line of the question: "For drug/addiction specialist only". I have seen that we have an addiction specialist answer here from time to time and he might know. Please know that it might take more time for him (or another similar doctor) to respond as they aren't always on this site.
