Duration of Cannabis Presence in Saliva

Cannabis can be detected in saliva for about 1 to 2 days following last use for occasional users, and up to a week for regular users.

Factors Influencing Cannabis Detection in Saliva

The detection window of cannabis in saliva can be influenced by several factors, including:

  • Individual’s metabolism
  • Frequency of use
  • Amount consumed
  • Strength of the cannabis

Understanding Saliva Tests for Cannabis

Saliva tests are often used due to their non-invasive nature and ability to detect recent use of cannabis. They function by detecting Delta-9-THC, the active component in cannabis.

It’s important to note that these tests are generally sensitive and may indicate a positive result even in case of passive exposure to cannabis smoke.

Medical cannabis users and people using CBD products should be aware that depending on the THC content of their medication, they could also test positive in a saliva test.

Cannabis and Legality in the UK

In the UK, cannabis is classified as a Class B drug. Use for recreational purposes is illegal. However, medical cannabis has been legal since November 2018 for patients with particular medical conditions when prescribed by a specialist doctor.
