  • Moderate users: 5 to 7 days
  • Daily users: 10 to 15 days
  • Heavy daily use: more than 30 days

Blood Test

According to an article in Therapeutic Drug Monitoring, Cannabis is typically detectable in the blood for 1 to 2 days. However, in some cases, it’s been detected after 25 days. Daily use of cannabis can increase the length of time it is detectable.

Saliva Test

  • Occasional users: 1 to 3 days
  • Daily users: 1 to 29 days

Cannabis can enter the saliva through smoking flower or concentrates. However, its metabolites are only present in saliva after cannabis has been smoked or ingested.
