Webinar: THC/Cannabis - Recognizing Impairment

September 29, 2021 from 2:00pm-3:30pm Eastern

Webinar Faculty: Ed Barley  

About the Webinar: With the legalization of marijuana and the recent innovations in the delivery and ingestion of Cannabis in both psychoactive and non-psychoactive forms, there has been a surge of Cannabis related cases in the criminal arena. This presentation is designed to educate attorneys and investigators on how to challenge the DRE process and how it applies when Cannabis is the drug perceived to be resulting in impairment.
Topics will include
• Chemical breakdown
• Toxicology
• Retrograde extrapolation discussion
• DRE – a review of the 12-step evaluation
• Scientific studies
• Court cases
• Pitfalls
Upon completion of this course, the attendee will:
1) Be familiar with the chemical breakdown of THC and understand the psychoactive vs non-psychoactive metabolites.
2) Have an understanding of the pseudo-science behind DRE 12-step process
3) Be aware of the pitfalls of Field Sobriety Tests and the DRE examination
4) Be familiar with some studies and court cases related to THC and DRE examinations

NAPD doesn't apply for CLE or track attendance to provide certifications for our live webinars, conferences and online courses. This helps us keep the price as low as possible and avoids the disruption of the flow of the training required by many states to verify attendance.
We are able to provide CLE for dozens of recorded sessions from previous training for NAPD members in most states.   These sessions are only $10 per credit hour.   For more details, log in with your NAPD credentials at this link.
