> 2ug / litre of THC in the blood is a drug-driving offence
So I can have up to 8ug of THC in my blood? If I took 0.1mg (100ug) of THC (and would be very NOT high in this case, as it is 1/100th of a "normal" dose) I would probably be over the limit in that case, so sure they may be able to test for THC in the blood, but the limit is so laughably low as to effectively ban cannabis users from driving.
