Common Drugs Screened During Employment Drug Testing
Employment drug testing has become a standard practice in many industries. Companies use drug tests to ensure that employees are safe, focused, and capable of performing their jobs without impairment. Drug testing not only supports a safe workplace but also promotes productivity, reduces absenteeism, and boosts morale.
If you’re implementing a drug testing policy or simply want to understand what’s included in an employment drug test, it’s helpful to know which substances are typically screened. In this post, we’ll explore the most common drugs screened during employment testing and why companies choose to test for each.
Why Do Companies Drug Test?
Before we dive into the specifics, let’s look at why companies drug test in the first place. Drug testing helps companies maintain a safe and healthy work environment. Employees who use drugs can pose safety risks, especially if they operate machinery, drive, or work in high-stress roles. Impairment from drugs can also lead to poor decision-making, decreased productivity, and strained team relationships.
Drug testing also protects the company’s reputation. By maintaining a drug-free workplace, companies demonstrate their commitment to professionalism and safety. Many clients and customers appreciate working with businesses that prioritize safety and reliability.
Types of Drug Tests Commonly Used
The most common types of drug tests are urine tests, saliva tests, blood tests, and hair tests. Each type has its own strengths:
- Urine Tests: The most widely used, these tests detect a broad range of drugs and are easy to administer.
- Saliva Tests: Quick and non-invasive, saliva tests are effective for detecting recent drug use.
- Blood Tests: While more invasive, blood tests provide accurate results and are often used when immediate impairment needs to be determined.
- Hair Tests: These detect drug use over a longer period, making them useful for identifying past drug use.
Different tests can detect different time frames for drug use. For instance, urine and saliva tests are better for identifying recent use, while hair tests can detect longer-term usage.
Common Drugs Screened During Employment Testing
Each drug test, or “panel,” screens for specific substances. The number of panels (5-panel, 10-panel, or 14-panel) refers to the number of drugs included in the test. Let’s look at the most common drugs screened and why they’re included in employment drug testing.
1. Marijuana (THC)
Marijuana is one of the most commonly tested drugs in the workplace. Although it’s legal for recreational or medical use in many states, it can still impair focus, judgment, and motor skills. For this reason, employers often include it in drug tests, especially in safety-sensitive roles.
Marijuana can stay in the body for days or even weeks, depending on the individual and frequency of use. It’s typically detected through urine, saliva, or hair tests. Employers include marijuana in drug tests to prevent potential safety issues and maintain productivity.
2. Cocaine
Cocaine is a powerful stimulant that can create feelings of extreme energy, confidence, and alertness. However, it also causes risky behaviors, impaired judgment, and can lead to serious health issues. Cocaine can significantly affect focus and impulse control, which are critical for many jobs.
This drug is particularly concerning in industries where safety is essential. Cocaine can be detected in urine and saliva for up to a few days after use, while hair tests can detect it for months. Employers test for cocaine to ensure employees are making safe, rational decisions on the job.
3. Amphetamines and Methamphetamines
Amphetamines, including methamphetamines, are stimulants often used illegally. They’re known to boost energy and focus but also cause erratic behavior, aggression, and severe health risks when misused. Drugs like Adderall, which is a prescription amphetamine, may show up on drug tests, too.
Methamphetamine, often known as meth, is a particularly harmful form of amphetamine. It’s associated with serious health risks and aggressive behavior, making it a high-priority drug for testing. Employers test for amphetamines and methamphetamines to ensure employees are not taking substances that could lead to aggressive or risky behavior.
4. Opiates and Opioids
Opiates (derived from opium) and synthetic opioids are highly addictive painkillers. They’re often prescribed legally for pain but are also frequently abused. Examples of opioids include heroin, morphine, codeine, oxycodone, and fentanyl. These substances can cause drowsiness, impaired motor skills, and respiratory depression, all of which can create severe risks in the workplace.
Opioid addiction has become a major issue, leading many companies to include them in routine testing. Testing for opiates helps companies protect employees and support those who may be struggling with addiction. Employers can detect opiates through urine and saliva tests, and hair tests can show longer-term use.
5. Phencyclidine (PCP)
PCP, also known as “angel dust,” is a powerful hallucinogen that can cause delusions, hallucinations, and violent behavior. While not as common as other drugs, PCP poses unique risks due to its extreme psychological effects. Users may become aggressive or paranoid, which can lead to dangerous situations in the workplace.
Due to these effects, PCP is often included in drug tests, especially in industries where safety is paramount. PCP can be detected in urine for several days after use, and hair tests can show longer histories.
6. Benzodiazepines
Benzodiazepines are prescription drugs used to treat anxiety, insomnia, and seizures. Common examples include Valium, Xanax, and Ativan. While they’re legal when prescribed, benzodiazepines are sometimes misused, leading to drowsiness, confusion, and poor coordination. This can create risks, especially in jobs that require alertness or physical activity.
Because these drugs can impair performance, they’re often included in employment drug tests. Employers test for benzodiazepines to ensure employees are safe and capable of performing their duties effectively.
7. Barbiturates
Barbiturates are sedatives that were once widely prescribed for anxiety and sleep disorders. Although they’re less common today, they’re still available and sometimes misused. Barbiturates can cause drowsiness, lack of focus, and impaired motor skills, making them risky in any work environment.
Including barbiturates in drug testing allows employers to detect any misuse and ensure that employees are alert and safe on the job. Most standard drug tests can detect barbiturates through urine samples, and hair tests can show extended use.
8. Methadone
Methadone is a synthetic opioid often used to treat pain or opioid addiction. Although it has medical uses, methadone can impair alertness and motor skills when misused. Because of this, it’s often included in employment drug tests, especially in safety-sensitive roles.
Methadone testing allows employers to ensure that employees using the drug are taking it responsibly and are not impaired at work. Like other opioids, it’s detectable through urine and saliva tests, and hair tests can show past use.
Why Employers Test for Prescription Drugs
Prescription drugs, when used as directed, are legal and safe for most users. However, they can still impair focus, coordination, or judgment, especially in safety-sensitive roles. Employers test for certain prescription drugs to ensure that employees are capable of performing their duties effectively and safely.
When testing for prescription drugs, it’s important for employers to respect privacy and handle results fairly. Employees with a legal prescription may still test positive, so employers should follow company policy and consult with HR before taking action.
Legal and Ethical Considerations
While drug testing can benefit a workplace, it’s essential to conduct tests legally and respectfully. Employment drug testing laws vary by state and industry, so it’s essential to understand local regulations before implementing a policy. Some states restrict the types of drugs that can be tested or limit testing to specific situations.
It’s also important to consider employees’ rights. Drug testing can feel invasive, so ensuring confidentiality and professionalism is essential. Drug test results should be kept private, shared only with relevant personnel, and used according to the company’s policy.
Conclusion: Ensuring a Safe, Productive Workplace
Drug testing is a powerful tool for creating a safe, productive, and drug-free workplace. By understanding which drugs are typically screened in employment testing, companies can implement fair, effective policies that protect their employees and their reputation. Common drugs like marijuana, cocaine, amphetamines, opiates, and benzodiazepines are included in many tests due to their potential to impair performance.
However, it’s important to approach drug testing with respect and consistency. Clear policies, confidentiality, and legal compliance are key to building trust and maintaining a positive work environment. When handled thoughtfully, drug testing contributes to a workplace where employees feel safe, supported, and empowered to perform at their best.
