It will be interesting to read the actual study when it comes out.

Interesting questions: * What is the baseline of consumption / THC level?

* what was the alcohol level in decesased drivers ? (e..g how many people only had alcohol, how many only THC, how many had both, how many had nothing.

* Are there other test scenarios where THC screening is mandatory that could help getting to the baseline ? Are there ways to get an approximate answer from sewers, like they did for Covid?
