Urine Drug Screening (MORPHINE & CANNABINOIDS)

A urine drug test, also known as a urine drug screen or a UDS, is a painless test. It analyzes your urine for the presence of certain illegal drugs and prescription medications.

Urine is preferred because its collection is noninvasive and inexpensive, and drugs and their metabolites tend to concentrate in the urine over time. Of all the matrices, urine is the most commonly used for adolescent drug testing and is the most thoroughly studied.

Urine offers a somewhat longer window of detection for substances, usually varying from one day after consumption to several weeks. Most drugs are detected in urine for 24-48 hours after the last use.


Strengths of urine drug screening

  • Typically preferred matrix for adherence and drug exposure testing
  • Longer window of drug detection than in blood
  • Adequate specimen volume for drug screening and confirmation
  • Drug markers (parent drug or metabolites) are present in high concentrations


Morphine (Opiate) 2 to 5 days
Cannabis (Marijuana) 1 to 30 days


How to take the test

You will likely take the urine drug test in a bathroom specifically prepared for drug testing. The test procedure includes the following steps:

You will receive a specimen cup from the person administering the test.
Urinate into the cup. You need to produce at least 45 millilitres for the sample.
When you finish urinating, put a lid on the cup and bring it to the technician.
