Marijuana Breath Test Achieves Major Technical Milestone: Cannabix Breath Collection Unit Achieves UL and CSA Safety Certifications

Vancouver, British Columbia, May 13, 2026 – Cannabix Technologies Inc. (CSE: BLO) (OTCID: BLOZF) (Frankfurt: 8CT) (the “Company or Cannabix”) is pleased to announce that its portable Breath Collection Unit (BCU), a core component of the Company’s Marijuana Breath Test (MBT), has successfully achieved Underwriters Laboratories (UL) and Canadian Standards Association (CSA) electrical safety certifications. The BCU along with Cannabix’s proprietary Breath Cartridges are core hardware products of the MBT system.

The Cannabix BCU has been certified to UL 61010‑1 (United States) and CSA 61010‑1-12 (Canadian) standards which are recognized North American safety standards that confirm a device is safe and suitable for professional, industrial, and regulated use.  Testing and certification were completed at an independent ISO/IEC 17025 accredited laboratory recognized in both Canada and the United States for electrical safety evaluations.

UL and CSA certifications are widely recognized top tier safety standards for electrical equipment used in the marketplace. Achieving certification under both safety standards represents an important regulatory, technical and commercial milestone for Cannabix as it advances its marijuana breath testing technology toward broader deployment.

These certifications will help:

• Facilitate adoption by workplace safety, industrial, law enforcement and government customers that require UL and CSA compliance as a condition of procurement. Certification positions the BCU to be considered for formal tender processes and approved vendor lists that were previously inaccessible without it.
• Support commercialization efforts in both United States and Canada, reducing regulatory friction for pilot programs and sales
• Demonstrate product safety, reliability, and manufacturing quality, enhancing confidence among prospective partners, customers, and regulators
• Enable smoother integration into safety‑critical and regulated environments

The Cannabix BCU is designed to capture breath samples for laboratory analysis. Successfully meeting UL and CSA safety requirements validates the Company’s engineering and design approach and aligns with its strategy to build regulatory‑ready technology for real‑world use.

 “Achieving both UL and CSA certifications for our Breath Collection Unit is a major milestone for Cannabix that reflects our focus on product safety, quality, and regulatory compliance as we continue positioning our technology during phased commercial deployment.” Stated, Rav Mlait, CEO Cannabix Technologies Inc.

Positioning for Future Growth

As regulatory scrutiny and demand increase for non‑invasive, recent-use marijuana screening solutions, The Company believes that compliance with recognized international safety standards will be an important enabler for scaling adoption. The Company expects these certifications to support ongoing discussions with government agencies, employers, and strategic partners seeking compliant and reliable testing solutions.

The Marijuana Breath Test (MBT) incorporates Cannabix’s proprietary Breath Collection Unit and Breath Cartridge technologies, designed to collect and preserve breath samples for analysis using gold-standard liquid chromatography-mass spectrometry (LC-MS) methods.
