Just for those who didn't realise... http://www.rta.nsw.gov.au/roadsafety/drinkdriving/drugs/index.html Personally I think it is a good thing although it would be interesting to know how long after taking drugs will this test still register. Is it a day, a week or a month? I have been told they can detect cannabis use in blood samples up to 3 months after. The only annoying part of this is that the test isn't as simple as the normal 1 minute RBT style test. You have to wait 5 minutes for a result. Do the tests in Victoria take this long? You'd be pretty annoyed if you were running late or just nipping down the street and maybe lose up to 10 minutes at the RDT.
