Hello Communtiy! I started taking "Hydrocodone" this past year!, and my bloodwork sample says they found "Propoxyphene" in one month, and next month they found "levorphanol"??? I borrowed a "hydrocodone" of a different color/shape before, and thought that since it has "hydrocodone" and "acetominophen" in it, that it wouldnt hurt?, but is it possible to produce these other two drugs that i mentioned by taking a different color/shape of Hydrocodone? can Somebody please help me on tis question? I would greatly apprecitate it, and thanks again Community!
