How to (Try to) Cheat a Drug Test

Attempting to fool a drug test has a long (and often entertaining) history.  Cheaters have been trying to figure out ways to pass a drug test ever since drug tests were invented. Thankfully, Worker Care is pretty good at sniffing out these cheaters, ensuring your employee is being kept honest. There are three primary ways to “try” to fool a drug Test: Dilution, Substitution, and Adulteration.
A “diluted specimen” is a urine sample that has a higher than average water content. The goal when diluting a sample is to minimize the drug levels visible in urine. Since many laboratories have specific cut-off points where, even if the drug is detected, it will not be marked as a positive result because there is very little in the sample, the cheater’s goal is to dilute the specimen enough that the drug can’t be detected.
To accomplish this, cheaters will intentionally over-consume large amounts of water prior to a drug test. This will lower drug ratios in the urine, but unfortunately for the cheater, this does not guarantee a negative result, and our laboratory will immediately flag the diluted sample.
Also, it is very common for people to try and add regular water directly to the urine sample. This is the reason that Worker Care adds dye to our toilets and shuts off our faucets. This is also very easy for us to detect.
This is one of the only methods of cheating a drug test that had a consistent rate of success at one point. Substituting a urine sample is when the donor provides urine that did not originally come from his or her body. There are two methods preferred by cheaters: sneaking in someone else’s urine, or substituting synthetic urine.
Cheaters usually try to sneak in someone else’s urine using several methods: sneaking it inside a Ziploc bag or condom, or using a device such as a Whizzinator. When using synthetic urine, the most popular form of this is from concentrate. Powdered urine can be purchased online in packets, and then mixed with water to form urine.
The biggest challenge for the cheater when using substitute urine is keeping the urine at the correct temperature. Chemical pocket warmers are commonly used to keep hidden urine warm. Providing one of Worker Care’s technicians with a cold (or overly hot) sample will immediately flag them, and they will be forced to retest. Even if we don’t catch them when we collect the sample, our lab has many ways of detecting substituted urine, and we have had the great pleasure of reporting these cheaters to many, many employers over the years.
An “adulterated specimen” is a urine sample that has been tampered with in some way. Adding certain chemicals to a urine sample will either mask the presence of drugs, or interfere with the laboratory equipment. These chemicals are also easily detected by our lab, and the specimen will be flagged as adulterated.
Common chemicals used for “doping” samples are soap, salt, bleach and eye drops. There are also “drug screens” sold online, such as, Goldenseal, QuickKlean or Mary Jane Super Clean 13. These products do little more than dilute or adulterate a sample. Any of them will flag the urine sample at the lab as tampered-with.
Rest assured, Worker Care is constantly updated our drug detection techniques and testing methods, keeping up with changes in technology and staying two-steps ahead of the cheaters.  If you’re interested in learning more about our drug testing procedures, please call us to make an appointment to come in and see our techniques, and we’ll happily walk you through how we catch these sneaky cheaters.
