Why Employers Still Use Drug Testing

Drug testing remains part of many employers’ hiring and workplace safety programs, especially where roles involve safety-sensitive duties, driving, equipment operation, or other elevated risk.

For many organizations, the question is not whether to test at all. It is how to build a program that is:

• consistent

• role-appropriate

• compliant

• practical to administer

That starts with understanding panel selection.

When Drug Testing Makes Sense

Drug testing is often considered when:

• the role involves safety-sensitive responsibilities

• the employer maintains a formal drug-free workplace policy

• insurance, customer, or internal risk requirements support testing

• the employer wants a consistent pre-employment screening process for specific job categories

The right program depends on the role, the employer’s policy, and applicable law.

What a 5-Panel Drug Test Covers

A 5-panel drug test is one of the most common employment-testing configurations.

It typically screens for:

• marijuana (THC)

• cocaine

• amphetamines

• opiates

• PCP

For many employers, a 5-panel test is the baseline option for pre-employment screening.

What a 10-Panel Drug Test Covers

A 10-panel drug test includes the five substances in a standard 5-panel test, plus additional drug categories that broaden the screen.

A 10-panel test typically includes:

• marijuana (THC)

• cocaine

• amphetamines

• opiates

• PCP

• barbiturates

• benzodiazepines

• methadone

• methaqualone

• propoxyphene

That expanded coverage can make sense for employers that want broader screening based on the role, workplace risk, or policy requirements.

Because the panel is broader, employers usually reserve 10-panel testing for positions where the additional scope is justified rather than applying it automatically to every role.

How Employers Choose Between 5-Panel and 10-Panel

A practical rule is to match the panel to the role.

5-panel testing often makes sense when:

• the employer wants a standard pre-employment screen

• the role does not require a broader panel

• the goal is consistency and efficiency across common hiring categories

10-panel testing may make sense when:

• the role carries elevated safety or operational risk

• the employer wants broader screening coverage

• internal policy or customer expectations support expanded testing

The key is consistency. Employees or candidates in the same role category should be screened under the same standard.

Common Employer Mistakes

Using one panel for every role

That can increase cost without improving decision quality. Panel choice should reflect the role.

Applying the policy inconsistently

If similar roles are screened differently without a clear reason, the program becomes harder to defend and harder to manage.

Ignoring timing in the hiring process

Drug testing affects start timing. Employers should build that into the hiring workflow instead of treating it as an afterthought.

Overlooking review and adjudication steps

If a result requires additional review, the employer’s next steps should follow a documented, consistent process.

Compliance Considerations

Drug-testing rules depend on the employer, the role, the state, and the testing context.

Employers should make sure their process addresses:

• disclosure and authorization requirements where applicable

• consistent role-based testing standards

• any required review procedures

• state-specific restrictions or protections that may apply

This is especially important in jurisdictions with changing cannabis-related employment rules.

Frequently Asked Questions

What is the difference between a 5-panel and a 10-panel drug test?

A 10-panel test includes the substances in a 5-panel test plus additional drug categories. Employers choose between them based on the role and the level of screening they want.

Which panel should employers use for pre-employment testing?

That depends on the role, the employer’s policy, and any applicable legal or operational requirements.

Does every job need the same drug test?

Usually not. Many employers align panel selection to the position category rather than using one standard for every role.

Can employers still test for marijuana?

That depends on the employer’s policy, the role, and the jurisdiction. Employers should review current state and local rules before finalizing their program.

How should employers handle a positive result?

Positive results should be handled through a documented, compliant process rather than through ad hoc decision-making.

What to Do Next

A well-structured drug testing program should match the role, the risk, and the law. The right panel is not the broadest panel by default. It is the one that fits the job and your policy. Get started with screening your employees below!
