Just a little refresher,

To date, oral fluid is the most studied and promising alternative matrix for DUID programs. However, THC is detected in oral fluid for 48 hours in chronic smokers during sustained abstinence.

"Exhaled breath may offer an alternative to oral fluid testing as cannabinoid detection in this matrix may better coincide with impairment."

Cannabis effects on driving skills:

"Evidence suggests recent smoking and/or blood THC concentrations 2–5 ng/mL are associated with substantial driving impairment, particularly in occasional smokers."

Anywhere between 2 - 5 ng/mL will likely be the accepted threshold.
