I wouldn't be surprised if that there contains many opiates, and I'm sure morphine is in it, but not in any significant range (but if I understand correctly, he's just chemically experimenting).
My fiancee actually has a fairly large opium poppy patch she tends and occasionally makes opium from (God only knows what our first child-planning on next year-will grow), and the one time she tried to snatch morphine from the opium residue it came out horrible. What your friend will come out with, at best, is what is called crude morphine. But in order to get that, he must isolate it from the opium (what it appears you may have there). To refine the morphine, you have to heat it together with acetic anhyidride. Then there's a bunch of steps you have to do in order to purify the morphine into the traditional hydrochloride salt.
All in all, though, I do think there's a distinct potential, and I think your friend is worth his weight in salt, given his use of lime to precipitate.
Keep up the good work, and definitely keep us posted!
