Does CostCo Drug Test?

If you're applying for a job at Costco, you might be wondering: does Costco drug test? The short answer is yes — but the timing and type of test depend on the role you're applying for. While some entry-level positions may not be tested immediately, others — especially in management or safety-sensitive departments — often require a pre-employment screen.

Whether you're applying to stock shelves, work the register, or manage a department, here’s what you need to know about Costco’s drug testing policy in 2025.

Does Costco Drug Test at the Interview?

No, Costco does not drug test at the interview. Interviews typically focus on work history, availability, and team fit. If a test is required, it will be requested after a conditional offer of employment.

Does Costco Drug Test New Employees?

Yes. Costco does drug test new hires for most roles. Testing usually happens after a job offer but before orientation. It's part of the company’s commitment to maintaining a safe and productive workplace.

Does Costco Drug Test at Orientation?

Sometimes. If the drug test hasn’t been done pre-orientation, it may be conducted on-site during or immediately after orientation. Candidates are usually told in advance if this will be the case.

Does Costco Drug Test for Weed?

Yes — Costco does test for marijuana (THC) as part of their standard drug panel. However, how strictly it’s enforced may depend on your location. In states where cannabis is legal, some stores may be more lenient — but corporate policy still includes THC in most screening panels.

Does Costco Random Drug Test?

Costco reserves the right to conduct random drug tests, but it's not common for most store-level roles. Random testing is more likely in warehouse, machinery, and pharmacy-related positions, or if there’s reasonable suspicion of substance use.

Which Costco Roles Might Require Drug Testing?

• Warehouse & stockroom workers
• Supervisors and department managers
• Forklift operators and equipment handlers
• Pharmacy and optical staff
• Corporate and administrative roles

Is Weed a Disqualifier for Costco Jobs?

Potentially, yes. Costco tests for THC, and a positive result could disqualify you — even in states where recreational use is legal. However, enforcement varies by role and region, and some candidates have reported second chances or retests.
