How Long Does Morphine Stay In Your Blood?

Medically Reviewed by Johnelle Smith, M.D on April 30, 2021

Morphine is a prescription opiate that is rapidly absorbed and metabolized. This means it will leave the blood quickly. The average detection time for morphine in blood may vary based on biological and personal factors related to drug use.

How Long Can Morphine Be Detected In Your Blood?

Blood testing methods will only be able to detect morphine use for a short amount of time: 12-24 hours.

Other drug tests that can screen for morphine use include:

  • urine tests: one to three days
  • saliva tests: 48 to 72 hours
  • hair follicle tests: up to 90 days

If you’re suspected of misusing morphine, a blood test may be ordered to monitor your drug use.

Detecting Morphine Through Blood Tests

On average, morphine can be detected in the blood for between 12 and 24 hours after its last use.

What Factors Affect How Long Morphine Stays In Blood?

Blood tests will typically be able to detect morphine for 12 to 24 hours after your last dose. This is the average amount of time for the general population.

Factors that can affect this average timeframe include:

  • amount taken
  • frequency of use
  • drug formulation (i.e. immediate vs. extended-release)
  • method of use (e.g. morphine injection)
  • use of multiple drugs
  • metabolic rate

Personal factors—such as age, liver and kidney function, and body fat—may affect the process of drug metabolism. This can potentially result in a longer detection window.

How To Get Morphine Out Of Your System

The only way to get a negative result for morphine use is to stop taking it. If you’re physically dependent on morphine, this may cause uncomfortable morphine withdrawal symptoms.

Stopping morphine all at once can be difficult, or even dangerous to attempt if you’ve been abusing morphine or have become addicted. In this case, a detox program is recommended.

Inpatient detox programs can offer:

  • 24-hour medical supervision
  • treatment for withdrawal symptoms
  • recommendations for additional substance abuse treatment

If you’re addicted to morphine, additional treatment may be recommended. Many detox centers work with drug rehab centers to coordinate additional care for people overcoming addiction.
