Last Updated on July 4, 2023 by Lily

Pre-employment drug screenings have become a standard practice for many employers as part of their hiring process. These screenings are conducted to ensure a safe and drug-free workplace environment. If you are a job seeker or someone preparing for a pre-employment drug screening, it’s important to understand what substances these tests typically look for. In this article, we will provide a comprehensive overview of what pre-employment drug screenings test for, including commonly screened substances, testing methods, and the importance of accurate and honest disclosure.

Commonly Screened Substances:

Pre-employment drug screenings typically test for a range of commonly abused substances. The specific substances tested can vary based on the employer’s policy, industry regulations, and the type of drug test conducted. Here are some substances that are often screened for:

Marijuana (THC): Marijuana is one of the most commonly screened substances. The screening tests for the presence of delta-9-tetrahydrocannabinol (THC), the active component of marijuana.

Cocaine: Cocaine is another substance commonly screened for in pre-employment drug tests. It is a powerful stimulant drug derived from the coca plant.

Amphetamines: Amphetamines, including drugs like methamphetamine and prescription medications like Adderall, are screened for in pre-employment drug tests. These substances are known for their stimulant effects.

Opioids: Opioids, such as heroin, morphine, codeine, and prescription painkillers like oxycodone and hydrocodone, are frequently screened for due to their potential for abuse and addiction.

Benzodiazepines: Benzodiazepines, which are commonly prescribed for anxiety and sleep disorders, are screened for in some pre-employment drug tests. Examples include medications like Xanax, Valium, and Ativan.

Phencyclidine (PCP): PCP is a dissociative hallucinogenic drug that is screened for in certain pre-employment drug tests. It is known for its mind-altering effects.

Testing Methods:

Different testing methods are used in pre-employment drug screenings, each with its own advantages and detection windows. The most common testing methods include:

Urine Tests: Urine tests are the most frequently used method for pre-employment drug screenings. They can detect drug metabolites and provide a detection window of up to several days, depending on the substance.

Hair Follicle Tests: Hair follicle tests involve analyzing a hair sample to detect drug use. These tests have a longer detection window, typically spanning several months.

Saliva Tests: Saliva tests are non-invasive and provide a shorter detection window compared to urine and hair follicle tests. They can detect recent drug use within a few hours to a few days.

Blood Tests: Blood tests provide real-time results and can detect the presence of drugs in the system. They are less common in pre-employment drug screenings due to their invasiveness and higher cost.

Importance of Accurate and Honest Disclosure:

It is crucial to provide accurate and honest information during pre-employment drug screenings. This includes disclosing any prescription medications you are taking, as some medications can potentially yield positive results. Employers and testing facilities understand the legitimate use of prescription drugs and take steps to ensure appropriate interpretation of test results.

Conclusion:

Pre-employment drug screenings aim to create a safe and drug-free work environment. These screenings typically test for commonly abused substances such as marijuana, cocaine, amphetamines, opioids, benzodiazepines, and PCP. The testing methods include urine tests, hair follicle tests, saliva tests, and, less commonly, blood tests. It is important to provide accurate and honest information during the screening process, especially regarding prescription medications, to ensure proper interpretation of test results. By understanding what pre-employment drug screenings test for, job seekers can approach the process with knowledge and confidence.
