You appear to be correct. I found some info saying that there are tests that check saliva for delta-9 THC and not metabolites, and can narrow it down to a 4 - 6 hour window since the last hit. I certainly don't support any form of impaired driving, but I still don't necessarily see that as any real proof of impairment.
I'd also be interested to see if the cited 6.8% were 'at fault' as opposed to just 'being involved' in the accident.
