Are False Negatives in Drug Testing Possible?

Since the use of drugs has increased all over the world, drug testing has also reached high figures. Due to this many abusers of drugs have been looking around for various methods in which they can beat drug test which have led to increasing number of myths, legends and misconceptions coming about regarding drug testing. Many of these myths are absolutely absurd while others are even disgusting. This post will mention a few of the misconceptions regarding intake of substances that will help show false negatives in drug tests.

The very first myth is that secondhand or passive exposure to drugs will cause the drug test to show a false negative. This myth can be true in certain cases but there are misconceptions present regarding this too. Medical studies show that for this myth to be true the amount of secondhand smoking and passive exposure is very large and asks for the person to be exposed to the drug or substance in a tightly sealed, small space for several hours. Hence a chance for a false negative to appear in case of secondhand exposure is at a very extreme level of exposure. Lastly this kind of exposure doesn’t affect hair follicles as substances are incorporated at the same level regardless of the fact that it is first or secondhand exposure.

Another myth is that high dosages of the medicine Ibuprofen can cause false negatives. This myth is true to some extent however, a false negative is shown in cases of extremely high dosages which is physically impossible for a person to intake. There is also a myth that states that poppy seeds can cause a false negative for the drug opiate. This is true in the case that a person eats or ingests 100 poppy seeds and only for the drug opiate.
