Depending on your tolerance, it would be a waste to cold water extract them. 10 of them (300 mg codeine) would be 3.25 grams of APAP, which, if taken occasionally, and if you don't drink a lot, would still be ok for you. To answer your other question, hydrocodone (vic's) is about 6 time as potent as codeine. As far as the feeling goes, you won't get the same buzz as you get from hydro. The equiv. is in analgesia, not euphoria. Interestingly enough, I read somewhere that Vicodin got it's name b/c hydrocodone is 6 X (VI) as potent as codiene (Codin).
