Codeine is a form of prescription opioid painkiller that is used to treat those suffering from mild to moderate pain. Codeine can be traced in urine, blood, hair, and saliva drug tests. Read below to see how long this drug stays in your system.

How long is Codeine detectable in your system?

The length of time codeine is detectable in the system varies depending on a variety of factors. These can include body mass index (BMI), how long the drug has been taken for, in what volume, age of user, and gender. It also changes depending on which of the four main types of identifying test is used. These are urine testing, blood testing, hair follicle testing, and saliva testing. The length of time codeine is identifiable in each test is as below.

Test type Time period
Urine Up to 3 days
Blood Up to 24 hours
Hair Up to 90 days
Saliva Up to 4 days

Factors that affect codeine detection times

There are many factors that can influence the detection rate in a toxicology test and these can vary from person to person. For instance, someone with a long history of opioid abuse, or someone who uses codeine in large quantities will have detectable opioid metabolites in their system for longer than someone who hasn’t. The same is also true if someone abuses multiple drugs or combines them with alcohol regularly. 

Other factors that influence crack cocaine detection rates include:

  • Body mass index (BMI)
  • Gender
  • Age
  • Pre-existing medical conditions (especially those involving the liver or kidneys)
