If you are suspected of using the drugs at other times (before 48 hours period) and you are tested through this method, then it is likely that your boss does not know about oral swab drug test THC detection times. The mouth swab drug test detection period is usually limited to a few hours and not days.
  2. The person who is performing the test will let the equipment come to room temperature first and ask you to spit out any gums you might have in your mouth.
  3. The cotton swab will be inserted into your mouth and your cheeks, gums, and tongues will also be swabbed for up to five minutes or when the swab gets saturated. This can be indicated with a line on the testing swab.
  4. The swab will then be removed and placed in a testing cup. Saliva drug test detection times for THC are usually 10 minutes. After 10 minutes the colored bands can show if drugs are present in your mouth or not.

Substances like opioids, cannabis (THC), phencyclidine (PCP), alcohol, barbiturates, benzodiazepines, amphetamines, and methamphetamines can be detected with saliva drug tests.
