Morning lads.
I've been investigating this 'drug driving' lark.
There's a zero tolerance approach to illegal drugs and the limit for an 'accidental exposure' plea of THC is 2ug/L.
2 microgram's of THC per litre of blood, any more than that and it's auto prosecution.
Next step is to wrap my head round the maths and try to work out the connection between subjective THC content of cannabis samples and a blood concentration level of 2ug/L.
According to Erowid the recommended dose to stimulate appetite (as in the USA) is 2.5mg.
That's 250x more than our limit, we're fucked!
