I was just given a drug test at my Dr. office. It showed positve for a low level of Morphine (78 ml). To my knowledge, I have never taken this drug. Does anyone know what would cause this? I have not taken any codeine lately either

Probably the test. The immediate read drug tests have a very high error rate (but usually only show positive or negative).

Also, any opiate would show positive for morphine and at that level any synthetic or semisynthetic opioid.
