Here is a cold water extraction for pills containing A/A (acetaminophen (tylenol)/asprin):

I just did it with 20pills 300mg/30mg - acetaminophen/Codien. I used 60ml water. I took 10ml today & felt great. That means 10ml = 3.33 pills codiene @ 30mg/pill ... so 3.33pills x 30mg = 100mg pure codiene since the acetaminophen was extracted (granted, not 100% of the acetaminophen was extracted, but its better than taking 600mg+). Acetaminophen is very liver toxic. I stay as far away from any A/A as possible. You can take opiates your whole live with very little negative side effects (that is if you dont over dose).

Any how ... enough blabber.
Best of luck,
