Will marijuana show up in tests as an opiate?

last guy: No THC is THC, the chemical found in marijuana. An opiate is a form of herion such as morphine or Oxycontin.

pip313: Technically it is a opioid because it has activity at opiate receptors, demerol is an "opioid" because it is fully synthetic with no structural simularity to anything the poppy plant produces. No one questions demeral being an opioid THC has the same quality's (again activity at the opiate receptors , at least the mu receptor)
