This course is designed for the uniformed officer who needs further knowledge on how to investigate DUI cases where the suspect may have ingested marijuana. This is not designed for a Drug Recognition Expert. It is designed for officers that have basic DUI training, SFST training, or ARIDE training.

States across the country are passing laws that legalize marijuana for recreational and medicinal use at a dizzying pace. Unfortunately, law enforcement has not been keeping up with the liberalization of marijuana laws. Studies have shown that marijuana DUI’s increased in states that have legalized marijuana. However, states have not been able to keep up with the demand of training our officers in the art of marijuana DUI detection.

Sending your entire agency to the Drug Recognition School isn’t an option either since the DRE course is an investment of over 2 weeks for each officer.

As I traveled the United States training our officers, I’ve asked them what the most important training they think they should have. Hands down, the majority of officers want to know more about how to do a marijuana DUI investigation.

This is the reason I designed this course. I designed it for the officer that has only basic DUI training, Standardized Field Sobriety Test training or maybe an ARIDE course. I’ll teach you some clues to look for in a marijuana DUI and how you can use this information in your investigation and ultimately your report.
