How Drug Screening Works and Why It’s Necessary

Drug screening is integral to many industries and institutions, such as workplaces, in-patient treatment programs, and sports organizations. These screenings look for signs of prescription, legal, or illegal drugs in a urine or hair sample. If you have an upcoming drug screening, you may have questions about the process. Here is what you should know.

An overview of drug screening

Drug screening, also known as drug testing, is collecting and analyzing a biological sample, such as blood, urine, hair, or saliva, for the presence of chemicals left in the body after drug or alcohol use. Drug screenings are common in workplaces, hospitals, and drug treatment centers. These screenings often test for the presence of:

• Alcohol
• Amphetamines
• Barbiturates
• Benzodiazepines
• Cocaine
• THC (marijuana)
• Opioids and opiates
• Phencyclidine (PCP)

They may also test for performance-enhancing drugs (PEDs) like steroids.

Types of drug screenings

Drugs and other substances metabolize in the body at different rates. Therefore, the timeframe for detecting different substances varies widely based on the substance used, the amount used, and how the body reacts to the drug.

Urine screenings

Urine tests are the most common type of drug screening due to its low cost and simple collection process. It requires a sample of one's urine. For example, a 5-panel or 10-panel urine test assesses a sample for specific prescription drugs and illegal substances. However, the 5-panel drug screen is used most often by employers for pre-employment screenings or workplace safety.

Saliva drug screenings

Also known as an oral fluid drug screening, saliva screening involves a medical provider using a swab to gather a sample from the patient's mouth. The drug detection period for saliva is shorter than other types of drug screenings. However, saliva tests offer an opportunity for employers to differentiate between recent (on-the-job) substance use and previous use.

Blood drug screenings

Blood drug screenings are more invasive than urine and saliva screenings. They are often common in emergency situations in healthcare facilities, such as overdose and DUI cases. These screenings can measure the precise amount of the drug in the bloodstream.

Hair drug screenings

Hair drug screenings provide the longest detection window, as they can identify drug use over a 90-day period. This type of drug screening analyzes the keratin in hair follicles, where drug metabolites accumulate as hair grows. While effective for long-term use patterns, hair tests do not detect recent drug use.

Breath drug screenings

This type of drug screening can detect recent alcohol consumption. The result of this screening is known as a breath alcohol concentration (BrAC). Police officers, medical providers, and employers can use this to estimate a person's blood alcohol content (BAC).

Why drug screening is necessary

Workplace safety

Individuals may need a drug screening for several reasons. The most common use of drug screening is for pre-employment requirements or workplace safety. Employees under the influence of drugs pose a health and safety risk, particularly in industries involving heavy machinery, transportation, or hazardous materials. Drug use can impair judgment, coordination, and reaction times, which can lead to accidents and injuries. Regular drug screenings can help to maintain a safe work environment and reduce workplace accidents.

In other situations, drug abuse can severely impact productivity and job performance. Employees who regularly use drugs may call in sick more, have lower productivity, and come in late to work. Implementing drug screening programs can help employers identify and address substance abuse issues, which can improve workplace efficiency and productivity.

Additionally, many industries are required by law to conduct drug screenings. For example, the Department of Transportation (DOT) mandates regular drug and alcohol testing for commercial drivers and pilots. Similarly, healthcare facilities often conduct drug tests to comply with state regulations and ensure patient safety. Compliance with these regulations is necessary for legal and operational standing, as well as worker safety.

Fairness in sports

In sports, drug screening is essential to ensure a level playing field. Performance-enhancing drugs such as human growth hormone (HGH) can give the athletes using them an unfair advantage compared to those who are not. These substances harm the integrity of athletic competitions. Drug screening can detect and deter steroid use, ensuring that achievements are based on athletic skill and hard work rather than illicit substances.

Detterance and rehabilitation

Regular drug screening often serves as a deterrent against drug use. Knowing that they could be tested at any time discourages employees, athletes, and other individuals from using drugs in their everyday lives. This preventive measure can help maintain a drug-free environment, promoting healthier and more responsible behavior.

Additionally, drug screening can contribute to health and rehabilitation efforts in drug treatment facilities. Identifying drug use early on can help people struggling with addiction receive the support and treatment they need. Medical providers can offer counseling and rehabilitation resources, aiding addiction recovery and promoting the patient's long-term well-being.
