Have drug testing questions? Get answers from Experts
I am online and will be happy to answer your questions.
coedine and morphine are both opiod class of drugs, so if urine test showed positive opiod it could be because of coedine, but if it specifically tested for morphine , then it would not be codeine. ( there are two different kind of tests, one only tests for class of drug and then one detects specifically the drug.) most screening tests only screen the class, so yes it is possibility to be coedine detected as positive morphine ( in real positive opioid).
am i making sense to you?
you can call lab and ask what technique they used, whether they detected class of drug or if they specifically looked for morphine.
marijuana use , like many other, depends on individual response of patient.
please let me know if i can provide further clarifications. thanks
Hello. I have a different opinion than the other expert.
In the body, codeine is metabolized into morphine. So, if someone is taking codeine, then the test for morphine will be positive. Even if the lab does a specific test for morphine, rather than for the opiate class, codeine can cause a positive test.
The test would also still be accurate 2 days later, if it has been stored correctly in a refrigerator. In fact, since she is known to be taking codeine, then this result is to be expected, so would be considered an accurate report.
The other expert is correct that there is no level of THC that is considered the threshold for impairment
If you are representing people for possible impairment, then a good consolidation of information for various drugs can be found at the National Highway Traffic and Safety Administration site. For example, the page for marijuana can be found at www.nhtsa.gov/people/injury/research/job185drugs/cannabis.htm with links to other drugs in the left column.
