Martin Savidge on the same show said they checked with a medical professional to get an idea of the amount and how it might impair him (given in nanograms...can't recall the exact amount but it is in the docs)
He said according to medical marijuana standards - it was 'right on the line' with what is the legal standard with being impaired to drive a vehicle.
Hey, I don't make too much of a 17 yr. old kid who has smoked a few joints...HOWEVER, what I want to know is how long ago this marijuana had been ingested. IOW, if the level was high enough to be 'right on the line' to be considered legally imparied to operate a vehicle, then I would think it had to be fairly recent. Not a week ago, kwim? I don't know... here to learn.
Please don't attack or misinterpret my reason for asking this. My MAIN reason is if it was very recent, that means he smoked since he had been visiting his dad. That leads me to wonder where the heck he got it considering his hometown and any connections were far away. Or maybe he brought it with him? I dunno.
