Hi all
Today is a really dark day!
I have smoked cannabis for 5 years, i am a productive member of society with a job and a car.
As of Monday 2nd March the UK police have the ability to test for cannabis and other drugs at the roadside, if you test positive, you will be banned from driving.
The test will be performed via an oral swab with a machine called "drugalyser" the limit for cannabis is 2mcg/litre of blood.
I am perfectly happy to not drive when i am high. However according to the following study, 4/6 people test positive 22 hours after smoking a spliff.

"10 participants provided 86 OF samples −0.5 h before and 0.25, 0.5, 1, 2, 3, 4, 6, and 22 h after initiation of smoking. Before smoking, OF samples of 4 and 9 participants were positive for THC and THCCOOH, respectively, but none were positive for CBD and CBN. Maximum THC, CBD, and CBN concentrations occurred within 0.5 h, with medians of 644, 30.4, and 49.0 μg/L, respectively. All samples were THC positive at 6 h (2.1–44.4 μg/L), and 4 of 6 were positive at 22 h."
Would your experience in australia suggest this study is true? I am not a scientist, but i cannot see how this study would be wrong or irrelevant?
