Pre-Employment Cannabis Testing
Washington's 2023 pre-employment cannabis testing law was a landmark change for employees and job seekers in the state. The law limits employers from making hiring decisions based on positive pre-employment cannabis tests in many circumstances — recognizing that off-duty cannabis use is legal and should not affect employment opportunities in most cases.
Important exceptions apply however — including safety-sensitive positions, federal contractors, and certain regulated industries. Understanding exactly how this law applies to your specific situation is important before assuming full protection.

Adults 21 and older can legally purchase, possess, and consume cannabis in Washington state. Medical cannabis has been legal since 1998. Cannabis remains federally illegal under the Controlled Substances Act — Washington's legalization applies only within state boundaries.

Can my employer still test me for cannabis in Washington state?
Washington's 2023 cannabis employment law limits employers from discriminating against job applicants based on off-duty cannabis use in many circumstances. Employers can no longer require pre-employment cannabis tests or refuse to hire someone based solely on a positive cannabis test result for most positions. However important exceptions apply — including safety-sensitive positions, federal contractors, law enforcement, and certain regulated industries. If you work in one of these categories the protections may not fully apply. Consult our full blog post or a Washington employment attorney for guidance specific to your situation.
Can I travel with cannabis purchased in Washington state?
Cannabis purchased legally in Washington must remain in Washington. Transporting cannabis across state lines is a federal offense under the Controlled Substances Act regardless of whether cannabis is legal in the destination state. This applies to driving across state borders, traveling by air — TSA agents are required to report cannabis found during screening — and traveling by ferry to international destinations. Within Washington state you may transport legally purchased cannabis in your vehicle as long as it is in its original sealed packaging and you are not consuming while driving.
What does Washington state require cannabis products to be tested for?
Washington state requires all licensed cannabis products to be tested by an accredited third-party laboratory before reaching retail shelves. Required testing covers potency (THC and CBD content), pesticides, heavy metals including lead and cadmium, residual solvents from extraction processes, mycotoxins including aflatoxins, and microbial contaminants including E. coli and salmonella. Medical-grade DOH-compliant products are subject to even stricter testing requirements. This comprehensive testing framework is one of the reasons buying from a licensed Washington dispensary like Hashtag is significantly safer than purchasing from unregulated sources.
What are Washington state's cannabis packaging requirements?
Washington requires all cannabis products to be sold in child-resistant, tamper-evident packaging. Most products require opaque packaging to prevent visual identification of contents. All packaging must carry required warnings, potency information per serving, total cannabinoid content, net weight, producer and processor information, and lab test results. These requirements ensure consumers know exactly what they're purchasing and help prevent accidental consumption by children.
