Roadside drug test detection times

Drugs are detected in saliva for up to a maximum of 72 hours after last use although many drugs including Cannabis are cleared much more quickly. Cannabis is usually only detectable in saliva for up to 12 hours since last use. The advantage of saliva drug screening for roadside testing is that it looks for active impairment, as it mainly detects drugs that have been consumed within hours of the roadside drug test being performed rather than days.
