Detection times for drugs on roadside drug test

  • 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 and often in practice a much shorter time
  • The advantage of saliva drug screening for roadside drug testing is that it looks for active impairment, as it mainly detects drugs that have been consumed within hours of the drug test being performed rather than days.
