Can Employers Drug Test Interns? What Employers and Interns Should Know
Internships play an important role in career development, offering students and recent graduates real-world work experience. As internships become more structured and regulated, many employers and interns ask an important question: Can employers drug test interns?
In most cases, yes—employers can drug test interns, but the rules depend on employment classification, state law, company policy, and whether the internship is paid or unpaid. Drug testing interns must be handled carefully to ensure compliance with labor laws, privacy regulations, and anti-discrimination requirements.
This comprehensive guide explains whether interns can be drug tested, when testing is allowed, legal considerations, consent requirements, and best practices for employers.
Are Interns Considered Employees?
Whether an employer can drug test an intern often depends on whether the intern is legally classified as an employee.
Paid Interns
Paid interns are generally considered employees. As a result:
- They are typically subject to the same drug testing policies as other employees
- Pre-employment, random, and post-incident testing may be allowed
- Employment laws usually apply
Unpaid Interns
Unpaid interns may fall under different legal classifications, especially in educational or nonprofit settings.
Employers may still drug test unpaid interns, but they must:
- Clearly disclose the policy
- Obtain written consent
- Apply the policy consistently
When Can Employers Drug Test Interns?
Drug testing interns is typically permitted under the same circumstances as employee testing.
1. Pre-Employment Drug Testing
Many employers require interns to pass a drug test before starting their internship.
Pre-employment drug testing must:
- Be part of a written policy
- Be applied uniformly
- Comply with state and federal law
Interns should be informed of the requirement before accepting the position.
2. Random Drug Testing
Random drug testing may be allowed for interns if:
- The employer conducts random testing for all employees
- The policy is clearly stated
- Selection is truly random
Random testing is more common in safety-sensitive environments.
3. Post-Accident or Reasonable Suspicion Testing
Employers may drug test interns if:
- An accident occurs
- There is reasonable suspicion of drug use
- Safety concerns are present
Documentation of observed behavior is essential.
State Laws and Drug Testing Interns
Drug testing laws vary by state. Some states impose stricter requirements regarding notice, consent, and testing methods.
Common state-level considerations include:
- Advance notice requirements
- Written consent forms
- Restrictions on random testing
- Medical marijuana protections
Employers must follow the laws of the state where the internship is located.
Intern Drug Testing and Medical Marijuana
Medical marijuana laws add complexity to intern drug testing policies.
Key points:
- Marijuana remains illegal at the federal level
- Many states protect medical marijuana users
- Employers may still restrict on-the-job impairment
Policies should clearly define expectations and accommodations where required.
Drug Testing Methods Used for Interns
Employers may use several types of drug tests for interns.
Urine Drug Testing
- Most common
- Detects recent to past use
- Widely accepted in legal and workplace settings
Saliva (Oral Fluid) Testing

Consent and Disclosure Requirements
Before drug testing interns, employers must:
- Provide written notice

Failure to obtain proper consent may violate privacy or labor laws.
Can Interns Refuse a Drug Test?
Interns may refuse a drug test, but refusal can result in:

Employers must apply consequences consistently.
Equal Treatment and Anti-Discrimination Laws
Employers must ensure that drug testing interns does not violate:

Clear communication prevents misunderstandings and disputes.
