I just asked her and she has no idea what that pill could be. She is in doubt it is codiene since all the pills she has ever seen clearly state the dose in either 15, 30, or 50 mg. But if you are sure, just look on the bottle or ask the guy you got it from. After that type codiene into your search engine of choice to read the possible contradictions and side effects before you pop it.
or she pointed me to this one:
