THC / 8000C / 320.31 / Tutorials
April 12, 2019
Ottawa, ON
On April 12, 2019, 12 criminal defence lawyers met in Ottawa, Ontario to learn all they could about cannabis, THC, CBD, and metabolites. We learned about the theory of operation and the limitations of the Draeger DrugTest 5000, a device that has been designated as Approved Drug Screening Equipment. We discussed the potential for false positives. Our guest expert was Ben Joseph. The recording of his presentation is about 2 hours in length and is suitable for Ontario substantive CPD.
In the afternoon, participants were able to use an Intoxilyzer 8000 and a Guth 2100 wet-bath simulator hands-on. We studied actual alcohol standard. Our focus was on defences based on the conditions precedent to Criminal Code section 320.31 conclusive proof. The recording of the Intoxilyzer / 320.31 presentation is about 2 hours in length and is suitable for Ontario substantive CPD.
Participants also had access in the materials to 4 hours of "primer" video recordings of previously recorded classes. The recorded primer classes include:
