About DrugImpairment.com

Training and resources on drug impairment are often scattered, costly, or out of reach for those who need it most. Our mission is to connect practitioners from all disciplines with credible resources from top experts in a single, easily accessible platform.

We believe the key to success in this mission resides in three principles:
Industry-Leading Instructors

DrugImpairment.com is where experts in drug recognition, forensic & clinical toxicology, medicine, vision science, and other fields come together to offer training on the complex topic of drug impairment. Our multi-disciplinary approach and inclusion of instructors with real-world experience is unmatched. Read more.

On-Demand Accessibility

Opportunities for industry-leading training are rarely next door. Access is then limited by travel time, dependence on class / conference schedules, and often exorbitant travel costs. We deliver the training you need in asynchronous e-learning courses that can be taken when and where convenient for you.

Cost Effectiveness

Classic continuing education models include paying hundreds of dollars for webinars and thousands of dollars for conferences to access cutting edge content. We use a membership-based platform to scale content over time for otherwise impossibly low fees: allowing broader access to frontline practitioners.

Matthew Myers Founder DrugImpairment.com Bio Pic

The Founding of DrugImpairment.com

DrugImpairment.com was founded by Matt Myers, a career law enforcement officer who fought through repeated obstacles to get training on drug impairment. As a young officer, Matt frequently dealt with drivers on drug cases and recognized the need for training beyond basic field sobriety testing. Unfortunately,  his agency repeatedly declined to approve Drug Recognition Expert (DRE) training, citing a lack of need for advanced education in this area. Undeterred, Matt eventually completed DRE training and field certification on vacation leave. After initial DRE training, Matt was frustrated with the limited opportunities to continue education in that path. Further complicating matters, the high-quality training that did exist exceeded budgetary limitations of his agency – even after gaining more supportive management. Matt worked extra jobs to fund his attendance to the Borkenstein courses, several other trainings / conferences, and eventual completion of a master’s degree in Clinical Toxicology.  Having experienced the challenges of continued education in this space, he resolved to make training on drug impairment more accessible to everyone who needs it.
