What Jobs Require Drug Testing?

Pre-employment drug testing is one of the silent gatekeepers standing between American workers and securing a new job. Yet, despite its pivotal role in the hiring process, drug testing often slips under the radar during job search discussions.

Drug testing is more likely for specific roles and industries. As job seekers prepare their resumes and sharpen their interview skills, they should be aware that this seemingly simple step could make or break their success in the hiring process.

We wanted to take a closer look at drug testing in America’s job market to provide greater insight into its prevalence and the implications for job seekers. By examining LinkedIn job listings nationwide, we determined the extent to which various states and industries lean on pre-employment drug testing.

Key Findings on Industries That Require a Drug Test for a Job

• Technology-related industries such as IT and Engineering lead the nation in drug testing requirements, with 34.38% and 28.54% of total LinkedIn job listings requiring drug testing, respectively.
• Legal industry jobs required the least drug testing, with about 0.60% of total LinkedIn job listings requiring drug testing before hiring.
• New Mexico leads the nation in drug testing requirements for new hires, with about 2.3% of LinkedIn job listings requiring pre-hire drug screening.
• In New Jersey, job seekers are less likely to face a drug test for a job, with only about 0.26% of LinkedIn listings in the state requiring pre-hire drug screening

What Is Pre-Employment Drug Testing?

Pre-employment drug testing is a crucial step in the hiring process for many companies. Drug testing helps ensure that new hires are free of illegal drugs, thus reducing the risks of workplace accidents and maintaining high standards of workplace safety and integrity.

If an applicant refuses a pre-employment drug test, the employer will usually withdraw the job offer. For current employees, refusal may result in disciplinary action or termination and, in regulated industries, may lead to removal from safety-sensitive duties.

There are several methods of drug testing available to employers, each with its own advantages and specific use cases:

• Urine Testing: The most common form of drug testing for jobs is urine testing due to its simplicity, cost-effectiveness, and non-invasive nature. It is widely accepted and is the approved method for federally mandated drug screenings. Urine tests can detect drugs like marijuana, cocaine, opiates, amphetamines, PCP, and alcohol.
• Hair Testing: An alternative that is a less common drug test for jobs but still acceptable is hair testing. It provides a longer detection window compared to urine tests and can trace drug use back up to 90 days. Hair testing is particularly useful for identifying consistent or repeat drug use over time.
• Oral Fluid Testing (Saliva): This method is gaining popularity for its ease of administration and the difficulty in adulterating samples. It is effective for detecting drug use and potential substance abuse that occurred recently, typically within minutes to a few days.
• Blood Testing: Although it is the most invasive drug testing method, blood testing is highly accurate and can measure the exact amount of drugs present in the bloodstream at the time of the test.

Understanding the various testing methods allows employers to choose the most appropriate one based on their specific needs and regulatory requirements. Urine testing remains a staple due to its balance of cost, ease, and compliance with legal standards.

Why Employers Require Drug Tests

Employers require drug tests for a job to protect workplace safety, meet industry regulations, and maintain productivity. In fields like healthcare, transportation, and manufacturing, impairment can create serious risks to both employees and the public. Drug testing also helps companies comply with federal or state guidelines, especially in industries regulated by agencies such as the Department of Transportation. Beyond safety and compliance, some employers view testing as a way to promote accountability, reduce liability, and ensure that employees can perform their roles reliably.

Common drug testing timelines include:

• Pre-employment testing: Conducted after a conditional job offer and before the employee begins work to confirm eligibility.
• Random testing: Performed without advance notice at unpredictable intervals during employment to deter substance use.
• Post-accident testing: Administered after a workplace accident or safety incident to determine whether drugs or alcohol may have been a contributing factor.

Drug Testing Laws

Federal regulations, such as Executive Order 12564, mandate a drug-free workplace for federal employees. This order, established by Ronald Reagan in 1986, prohibits illegal drug use by federal employees both on and off duty, and requires each federal agency to develop its own drug-free workplace program.

These programs, along with guidelines set by laws like the Omnibus Transportation Employee Testing Act of 1991, dictate that roles such as truck drivers and machinery operators must pass a drug test before starting their duties, with ongoing testing requirements for DOT-regulated positions. Understanding these laws helps employers ensure compliance and uphold a safe and lawful working environment.

State laws legalizing medical or recreational marijuana can affect workplace testing policies. Although federal law still classifies marijuana as illegal, requiring strict compliance in federally regulated and safety-sensitive roles, some states restrict when private employers can test for marijuana or act on positive results. As a result, testing policies may vary based on whether federal or state law primarily applies.

Job Industries That Require Drug Testing

While the technology and engineering sectors are leading with the highest drug testing requirements in the nation—34.38% and 28.54% of job listings, respectively—other industries also maintain rigorous testing standards to ensure workplace safety and regulatory compliance.

• Transportation: Federal regulations mandate strict drug testing for transportation roles, including truck drivers and machinery operators, primarily to prevent accidents and ensure public safety.
• Healthcare: Given the high stakes involved in healthcare settings, protecting health is paramount, and employees, especially those in direct patient care roles, are often required to undergo drug testing.
• Construction and Manufacturing: These industries require drug testing due to the high-risk nature of the work, which often involves heavy machinery and the need for precise coordination.
• Public Safety and Government: Drug testing for jobs in these sectors are critical to ensure the integrity and reliability of those tasked with public welfare and safety.

Interestingly, the legal industry shows the least reliance on pre-employment drug testing, with only about 0.60% of job listings indicating such a requirement. This variation underscores that while drug testing is widespread, the intensity and frequency of its implementation can significantly differ depending on the specific roles and responsibilities within each industry.

The 10 U.S. States that Require Drug Testing the Most & Least

Overall, drug testing requirements are relatively low across the nation. Our study revealed New Mexico as the national leader in pre-employment drug testing requirements, with 2.298% of job posts requiring drug tests. The District of Columbia is the distant second place, but the gap between the two is stark, with only 1.057% of D.C. job posts requiring a drug test.

The East Coast and Northeastern states are less inclined towards pre-employment drug testing, with seven out of the top ten states requiring the least drug testing located there. This finding demonstrates a distinct geographical bias in applying drug tests within the hiring process, hinting at potential cultural, legislative, or industry-specific factors at play.

The U.S. States with the Highest Drug Testing Rates for Various Job Filters

Our examination of the American drug testing landscape revealed a significant contrast between pre-employment drug testing for entry-level vs. senior-level positions. For example, in Georgia, a substantial 63% of job listings that mandate drug testing are for entry-level roles. Along the same lines, a mere 2.6% of Maryland job listings for senior-level positions required a drug test, again demonstrating a distinct focus on drug screening in early-career candidates. 

Similarly, higher-salary jobs require drug testing more often than lower-paid positions. In California, for example, about 17% of jobs offering $40k+ salaries required drug testing while just above 8% of jobs offering $100k+ salaries in the state required drug testing.

Closing Thoughts

The U.S. pre-employment drug testing landscape is nuanced and hinges on variables like geographical location, industry, role level, and compensation. For job seekers in tech and engineering (especially in entry-level positions), being prepared for drug screening can make all the difference. 

The implications of workplace drug use stretch well beyond the job market. In the healthcare sector, the ramifications can be significant, which is why a drug test for job candidates in this field plays such an important role. If you or a loved one have experienced negligent medical care due to drug use among medical staff (or for any other reason), we can help.

Employers usually confirm positive results with a secondary test, known as a GC-MS (Gas Chromatography-Mass Spectrometry) test, to reduce the chance of false positives.

Methodology

To gain insight into U.S. pre-employment drug testing practices, we started with a list of all 50 U.S. states plus the District of Columbia. Then, using LinkedIn job postings, we searched for and collected data by state for jobs that “required drug testing” in April of 2023. To determine which states drug test the most, we divided the total number of job listings requiring drug testing in each state over the total number of job listings. Next, we determined which industries require the most drug testing before hiring by dividing the number of jobs industry-wide that require drug testing over the total number of jobs in said industry. Finally, to determine the states that drug test the most based on various filters and categories, we divided the total number of job listings that require drug testing per filter category over the total number of jobs that require drug testing in each state.
