How High? Who knows?

David v. Hernandez, No. B270133 (D2d6 July 25, 2017) 

Plaintiff in a car crash case, who was pretty badly hurt when his minivan hit a truck pulling a uey on the PCH, tested positive for THC when taken to the hospital. The Tucker wanted to get that into evidence as proof that Plaintiff was impaired, and thus at least partially at fault for the accident.
