re: #809 Political Atheist

I’m not convinced of the utility. When they talked about marijuana is a toxicology report, can they even tell what level of inebriation is there? Not hard to imagine an irrelevant joint the day before showing up in a screening, or just a weekend habit. Can technology tell from blood if a person was high or just a smoker? High or did coke two days earlier?
I would expect a blood draw from anyone apart from cops who fires a gun at a person let alone hits or kills them.

Answering the question I was bolding, yes they can determine level of inebriation. Unlike the urine test (which measures residue and which lingers for a long time) the blood test can tell exactly how much intoxicating material per unit of blood exists.
