​Trust Screen Lab provides professional marijuana (THC) testing services for employers, courts, organizations, and individuals. Marijuana testing is designed to detect the presence of THC (tetrahydrocannabinol), the primary psychoactive component of cannabis. All testing is conducted in a confidential, professional setting using established collection and handling procedures to support accurate and reliable results.​

Marijuana testing is commonly used for pre-employment screening, random and reasonable suspicion testing, post-accident investigations, court-ordered programs, and personal testing needs. While marijuana laws vary by state, many employers and regulated industries continue to require THC testing to meet workplace safety, compliance, and company policy requirements. Testing at Trust Screen Lab is performed by trained professionals following validated collection and reporting protocols. Samples are collected in a secure environment and processed using industry-approved screening methods.Results are released only to authorized parties, and chain-of-custody procedures are maintained when required to ensure accuracy and defensibility.​​

Marijuana testing services are available as part of multi-panel drug screens or as THC-specific testing. Laboratory confirmation testing is available for non-negative screening results to provide verified outcomes. All services are delivered with a focus on privacy, consistency, and compliance, allowing clients to move forward with confidence.
