I dunno Melbourn_madness, looks a bit suss to me;
"However, this time frame may be extended where there is regular usage of the drug. A driver may be prosecuted when THC isfound to be present."
Sounds like zero tollerance if there is ANY thc in the system. Their 2-3 hour time frame was im sure for someone who basically never smokes but has a one-off joint, even then i think they are asuming very fast metabolism of thc.
"The frequency of cannabis use may influence the level of Delta-9-THC in the
body. If the active metabolite of the parent drug is present then it is
having and influence on the ability to drive"
That sounds to me like they are saying "Well yeah, if some pothead smokes a gram a day or whatever, then yeah sure, after 3 days of non-smoking there will still be thc in their system, but hey, I mean, if theres thc in the system, then its in interests of public safety mate, we gotta get that maniac off the road"
THats kinda how i read that statement...
All i know, is that this can't be good for us. I mean, ok, might take a few fuckheads off the road, no doubt, however, I think a lot of people are gonna face a hard time from this even though they are responsible drivers.
I might do some research on how long it will take b4 heavy smokers can come up clean, then edit this msg..
And for a sidenote, |Gi'me a stoned driver over a drunk driver any day

Im not saying they'll be using the same testing method, but this is food for thought. Being busted 72 hours after mdma ingestion would be a nasty surprise i would think. I also know that the 14ours stated for pot will climb with higher levels of usage(obviously).
