Quick answer: Many temp agencies drug test, but not for every job. Whether you’re tested depends on the client company, the type of work and your state’s laws. Warehouse, forklift, driving, manufacturing and healthcare jobs are the most likely to require a test. The most common is a pre-employment urine test (5-panel or 10-panel), and the agency or employer usually pays for it.
If you’re signing up with a staffing agency, a drug test is one of the first things you may be asked to do. So, do temp agencies drug test before every job? Not always. This guide explains when temp agencies test, which jobs require it, what the test looks for, how long drugs show up, how marijuana rules differ in Florida, Nevada, New York, New Jersey and Texas, and what happens if you test positive.
Do temp agencies drug test? Why many do
When you work through a staffing agency, the agency is your employer, but you do the work at a client company. So the agency follows two sets of rules: its own hiring policy and the client’s requirements. If the client requires a drug-free workforce, the agency tests you before placing you there.
The most common reasons a temp agency drug tests are:
- The client requires it. This is the biggest reason. Many warehouses, manufacturers and healthcare employers won’t accept a worker without a negative test.
- The job is safety-sensitive. Running a forklift, operating machinery or working around heavy equipment carries real injury risk.
- Federal rules apply. Jobs regulated by the U.S. Department of Transportation, like commercial truck driving, require drug testing under 49 CFR Part 40.
- Insurance and state programs. In Florida, employers that run a certified drug-free workplace program can qualify for workers’ compensation insurance discounts.
Drug testing is common across the U.S. workforce. In its 2025 Drug Testing Index, Quest Diagnostics analyzed more than 8 million workplace drug tests and found that 4.4% came back positive in 2024.
At Jomsom Staffing, we conduct background checks and drug testing as required by our clients (see our job seeker FAQ). So when people ask us “do temp agencies drug test?”, our honest answer is: it depends on the specific job you’re placed in.
Do temp agencies drug test for every job? Which jobs require it
There’s no single rule, but some types of work are much more likely to require testing than others:
| Type of temp job | Drug test likely? | Why |
|---|---|---|
| Commercial driving (CDL) | Required | Federal DOT rules require pre-employment and random testing |
| Forklift operator | Very likely | Safety-sensitive equipment |
| Warehouse and distribution | Very likely | Client safety and insurance requirements |
| Manufacturing and assembly | Likely | Machinery and production-line safety |
| Healthcare support | Likely | Patient safety and access to medication |
| Skilled trades | Often | Tools, heights and job-site safety |
| Clerical and office | Sometimes | Depends on the client’s company policy |
| IT and professional | Sometimes | Depends on the client’s company policy |

When do temp agencies drug test?
- Pre-employment: the most common. You’re tested after you’re offered an assignment and before your first shift.
- Pre-assignment: if you move to a new client that has its own testing rules, you may be tested again.
- Random: mainly for DOT-regulated and other safety-sensitive jobs.
- Reasonable suspicion: when a supervisor sees signs of impairment on the job.
- Post-accident: after a workplace injury or accident, depending on company policy.
What kind of drug test do temp agencies use?
Most temp agencies use a urine test, either a quick instant test or a sample sent to a lab. Here’s how the common types compare:
| Test type | How it works | What it usually covers |
|---|---|---|
| 5-panel urine test | Urine sample at a clinic or collection site | Marijuana, cocaine, amphetamines, opioids, PCP |
| 10-panel urine test | Same as 5-panel, with more drugs | The 5 above plus drugs such as benzodiazepines, barbiturates, methadone and others |
| Instant (rapid) test | Results in minutes on site | Usually 5 to 10 panels; non-negative results are sent to a lab to confirm |
| Oral fluid (saliva) test | Mouth swab, often observed | Recent use, roughly the past day or two |
| Hair test | Small hair sample sent to a lab | A much longer window, often around the past 90 days |
The 5-panel test is the standard because it matches the five drug classes the federal government requires for transportation workers. Under 49 CFR §40.82, DOT labs test for marijuana, cocaine, amphetamines, opioids and phencyclidine (PCP), and nothing else.
How long do drugs show up on a urine test?
Detection times depend on the drug, how much and how often it was used, and your body. These are typical urine detection windows from the University of Washington Department of Family Medicine:
| Drug | Typical urine detection window |
|---|---|
| Marijuana (occasional use) | 2–4 days |
| Marijuana (heavy, daily use) | Up to 30 days |
| Cocaine | 2–4 days |
| Amphetamines / methamphetamine | 2–3 days |
| Opiates (morphine, codeine) | 1–3 days |
| Oxycodone | 1–3 days |
| Fentanyl | 1–3 days |
| Benzodiazepines | 1–3 days (short-acting) to 30 days (long-acting) |
These are ranges, not guarantees. The only sure way to pass is not to use drugs that aren’t prescribed to you.
Do temp agencies drug test for marijuana? Rules by state
Marijuana is where the rules vary most. Most standard panels still include it, but some states limit what an employer can do with a positive result. Here’s how it works in the states where Jomsom has offices:
| State | Marijuana and pre-employment drug tests |
|---|---|
| Florida | No job protection for marijuana use. Under Florida’s drug-free workplace law, employers can refuse to hire an applicant who refuses a test or has a confirmed positive result (Fla. Stat. §440.102). |
| Nevada | Employers generally can’t refuse to hire you just because a pre-employment test finds marijuana. Exceptions include firefighters, EMTs, jobs that require driving, and jobs that could affect other people’s safety (NRS 613.132). |
| New York | Employers generally can’t test for cannabis unless federal or state law requires it, or the worker shows specific signs of impairment on the job (NY Labor Law §201-d). |
| New Jersey | A positive marijuana test alone can’t be the reason for not hiring you. Employers can test when there’s reasonable suspicion of impairment at work (NJ Cannabis Regulatory Commission). |
| Texas | Almost no limits on private employer drug testing, and no job protection for marijuana use (Texas Workforce Commission). |
One important exception applies everywhere: jobs covered by federal DOT rules, such as commercial driving, still test for marijuana, even in states where it’s legal.
Who pays for a temp agency drug test?
You shouldn’t have to. When job seekers ask “do temp agencies drug test for free?”, the answer should be yes. The agency or the client company normally covers the cost. In New Jersey, the Temporary Workers’ Bill of Rights specifically bans temp agencies from charging workers for drug tests. Florida’s drug-free workplace law also requires employers to pay for the tests they require.
At Jomsom Staffing, our job placement services are completely free for job seekers. If any agency asks you to pay a fee to get placed, treat that as a red flag.
How long do temp agency drug test results take?
- Instant tests: a result in minutes. If it’s not clearly negative, the sample goes to a lab to confirm.
- Lab tests: negative results often come back within 1 to 3 business days.
- Positive or unclear results: take longer, because the lab runs a confirmation test and, for regulated tests, a Medical Review Officer reviews the result.
Most agencies ask you to take the test within 24 to 48 hours of getting the request, so go as soon as you can to avoid delaying your start date.
What if you take prescription medication?
Don’t panic. Legally prescribed medication shouldn’t cost you a job. If a test comes back positive for something you’re prescribed, a Medical Review Officer (MRO), a licensed doctor, will usually contact you privately to verify your prescription before the result goes to the employer. Under federal DOT rules, this verification interview is a required step (49 CFR Part 40, Subpart G).
Keep your prescription bottle or pharmacy record handy. You don’t need to share your medical details with your recruiter; the MRO handles it.
What happens if you fail or refuse a temp agency drug test?
If you test positive and the result is confirmed, the agency usually can’t place you with that client. Refusing to test is typically treated the same as a positive result. Depending on the agency’s policy, you may still qualify for other assignments that don’t require testing, so ask your recruiter.
Some states also give you a chance to respond:
- Florida: you can explain or contest a positive result within 5 working days, and request a retest of your sample at your own cost within 180 days.
- Nevada: if you’re tested within your first 30 days on the job, you can take a second test at your own cost to rebut the first, and the employer must consider it.
How to prepare for a temp agency drug test
- Ask your recruiter what to expect. Which test, where to go and the deadline.
- Bring a government-issued photo ID. Most collection sites won’t test you without one.
- Go as soon as possible. Delays can push back your start date or cost you the assignment.
- Don’t over-drink water. A very diluted sample can be flagged and may need a retest.
- Have your prescriptions ready in case the MRO calls.
- Follow up. If you haven’t heard back in a few business days, call your recruiter.

Frequently asked questions
Do temp agencies drug test everyone?
No. Many do, but it usually depends on the client and the job. Safety-sensitive jobs like warehouse, forklift, driving and manufacturing are the most likely to require a test, while many office jobs don’t.
Do temp agencies drug test for warehouse jobs?
Usually, yes. Most warehouse and distribution clients require a pre-employment drug test because of forklifts, machinery and other safety risks.
What drug test do temp agencies use?
Most use a 5-panel or 10-panel urine test. A 5-panel test checks for marijuana, cocaine, amphetamines, opioids and PCP. Some agencies use saliva or hair tests if the client requires them.
Do temp agencies do hair drug tests?
Some do, but it’s less common than a urine test. Hair tests are more expensive and look back much further, often around 90 days, so they’re usually used only when a client specifically asks for them.
Do temp agencies drug test randomly?
It can, if its policy or the client’s policy allows it and state law permits it. Random testing is most common in DOT-regulated and other safety-sensitive jobs.
Does Jomsom Staffing drug test?
Jomsom conducts background checks and drug testing as required by our clients. Your recruiter will tell you before you accept an assignment whether a test is needed, and our placement services are free for job seekers.
