Sticking by what I said originally. If you want to proceed you can however, you will always find the consensus to be "do not ingest unknown molds" there can be hundreds of subspecies or what have you that can occupy the same space. Mold and infection do kill people, ingesting via an oral route will provide some resistance but you are asking this question:
Is the relative risk of ingesting strange molds worth the reward of a possible successful morphine extraction? Among sane individuals the will (most likely) say that it is not worth the risks.
That doesnt mean if you go "szuko i hate you and think your wrong!" I will show up and cut your arms off so you cant proceed

Its the simple fact that even pills can contain compounds that can facilitate mold growth in a liquid medium, way to many variables for me to change my stance on the matter.
