DEFINITION:
A False Positive is a drug free sample falsely being reported as showing
positive for drugs.
This can occur for a number of
reasons including: improper laboratory procedure, mixing up samples, incorrect
paperwork and passive inhalation. But the most common cause of drug testing
false positives are cross reactants. A cross reactant is a substance which
because of its similar chemical structure to a drug or its metabolite can cause
a false positive result.
Drug Test Interaction With Medicines And Foods
Be aware that certain foods and
over-the-counter medications can cause you to test "positive" for various kinds
of drugs. Some simple examples are:
-
Poppy seeds, for example, can show up on a drug test as morphine.
-
Cold remedies that contain codeine can also cause a positive
result for morphine.
-
Valium reportedly can produce erroneous indications of PCP
(Phencyclidine), and other cold remedies can apparently produce false reports of
methamphetamine usage.
-
The widespread availability of hemp-containing products,
including everything from hemp-seed oil nutritional supplements to hemp-seed
candy, cookies, cheese, bread, cooking oil, and general seasoning, means that
ingesting ANY of these products could potentially cause a false positive result
on a test for marijuana.
Let's take a look at more specifics
in the are of false positive drug tests.
PLEASE READ THIS
DISCLAIMER: Let us
first say that not all drug tests are sensitive to all of the following and just
ingesting one or more of these ingredients will not guarantee a false positive
test. Also just by saying you have ingested one or more of these
ingredients will not automatically dismiss a false positive drug test.
These are just guidelines and should not be taken as absolutes.
