Detection Period - 7 to 45 days (depending on amount and frequency of use)

Detection Level - 50 nanograms/ML (the cut-off level suggested by the SAMHSA)


Marijuana is a common illegal drug prepared from the Cannabis plant genus.  The most important chemical compound in marijuana - the ingredient that makes it psychoactive - is delta-9-tetrahydrocannabinol, also known as THC.  Often when buying a drug test you will see marijuana referred to as THC.

A Marijuana Drug Test sold by Home Health Testing allows you to learn the test subject's recent drug history with a very simple test.  At any time of the day collect a urine specimen in a clean and dry container.  Dip the drug test card into the urine specimen and after 5 minutes you will know the results of your marijuana drug test (please follow the detailed directions found in our "Instructions" tab when conducting your test).  

The results of your marijuana drug test are very easy to read.  If the result of your test is negative, two lines will appear, one in the Control Region of the test card and one in the Test Region.  If positive, no line will appear in the Test Region of the marijuana drug test, but a line will appear in the Control Region of the drug test to show that the test was conducted successfully.  A positive result from your marijuana urine test means that the drug concentration in the urine sample is greater than the designated cut-off/detection level for marijuana.

According to the National Survey on Drug Use and Health, in 2007, 14.4 million Americans aged 12 or older used marijuana at least once in the month prior to being surveyed.   in 2007 about 6,000 people a day used marijuana for the first time—2.1 million Americans. Of these, 62.2 percent were under age 18.

How does a test this easy to use work?  When the marijuana drug test is properly used with the urine sample, the urine specimen migrates up the card by capillary action.  If THC is not present at a great enough level in the urine sample, it will not be able to prevent its antibody on the marijuana drug test card from reacting with the drug-protein conjugate on the test card.  When this reaction occurs a colored line appears in the Test Region and the result is Negative.  When marijuana is detectable in the urine it prevents the antibody from reacting with the drug-protein conjugate.  Therefore no colored line appears and the result of the marijuana drug test is Positive.

Materials Provided:

One Step Drug Screen Test Card
Package Insert


Materials Required But Not Provided:


Specimen collection container
Timer - a timer or timing device (such as a wrist watch) is required to run this test


1.  Conduct at room temperature and allow test card, urine specimen, and/or controls to equilibrate to room temperature prior to testing.  Have urine sample ready.

2.  Remove the test card from the sealed pouch and use it as soon as possible.  Remove "iScreen" labeled cap from end of the test card.

3.  With arrows pointing to the urine specimen, immerse the strip(s) of the test card vertically into the urine specimen for at least 10-15 seconds.  Immerse test card to at least the level of the wavy lines on the strip(s) but NOT above the arrow(s) on the test card.  Do NOT allow the plastic device/test card above the wavy lines to be touched by the urine.

4.  Replace cap and place the test card on a non-absorbent flat surface.  Start the timer and wait for the colored lines to appear.  The results should be read at 5 minutes.  Results remain stable for up to 4 hours after test initiation.


Interpretation of Results:


NEGATIVE:  Two lines appear.  A colored line appears in the Control Region (C) and a colored line appears in the Test Region (T).  A result should be considered negative whenever there is even a faint line - shades of colored lines in the T Region may vary.  Negative means that the concentrations in the urine sample are below the designated cut-off levels for a particular drug tested.  Please check your instructions for more information on the cut-off levels being used in your test.

POSITIVE:  A colored line appears in the Control Region (C) and NO line appears in the Test Region (T).  Positive means that the drug concentration in the urine sample is greater than the designated cut-off level for a specific drug.  Please check your instructions for more information on the cut-off levels being used in your test.

INVALID:  No line appears in the Control Region (C).  Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for Control line failure.  Read the directions again and repeat the test with a new test card.  If result is still invalid, contact manufacturer.


Warnings/Limitations


ALL SPECIMENS SHOULD BE CONSIDERED POTENTIALLY HAZARDOUS AND HANDLED IN THE SAME MANNER AS AN INFECTIOUS AGENT.

This test only provides a qualitative, preliminary analytical result.  A secondary analytical method must be used to obtain a confirmed result.  Gas chromatography/mass spectrometry (GC/MS) is preferred.

There is a possibility that technical or procedural errors, as well as other interfering substances in the urine specimen, may cause erroneous results.

Adulterants, such as bleach and/or alum, in urine specimens may produce erroneous results regardless of analytical method used.  If adulteration is suspected, test should be repeated with another urine specimen.

A Positive result does not indicate level of intoxication, administration route or concentration in urine.

A Negative result may not necessarily indicate drug-free urine.  Negative results can be obtained when drug is present but below cut-off level of the test.

Test does not distinguish between drugs of abuse and certain medications.

Urine specimen must be collected in a clean and dry container.

Urine collected at any time of the day may be used.

Urine specimens may be stored at 2-8 degrees Celsius for up to 48 hours prior to testing.  For prolonged storage, specimens may be frozen and stored below -20 degrees Celsius.  Frozen specimens should be thawed and mixed well before testing.

Test should remain in sealed pouch until use.  DO NOT FREEZE.  Do not use beyond expiration date.  Store at 2-30 degrees Celsius (36 to 86 degrees F).

Used test card should be discarded according to federal, state and local regulations.

  Frequently Asked Questions - Marijuana Urine Test

Q:  How long does marijuana stay in your urine?

A marijuana urine test cannot detect marijuana use immediately after the drug is taken.  It takes approximately 6-8 hours for marijuana to be detected in urine.  Thereafter, depending on a number of factors, marijuana can be detected in urine up to 15-30 days after its use.  According to Dr. Edward J. Cone from the National Institute on Drug Abuse, average detection time for most drugs in urine ranges from 1-5 days when the user is taking low doses or is only an occassional user. When an individual is a heavy or chronic drug user, the detection time for marijuana can be up to a month long.

Q:  How is marijuana taken?

Marijuana is usually smoked as a joint or cigarette or in  a pipe.  Marijuana can also be smoked in blunts or cigars that have the tobacco removed and refilled with marijuana.  Marijuana can also be mixed in food or brewed as a tea.

Q:  What are the behaviors of someone under the influence of marijuana?

Typical behaviors are euphoria, slowed thinking and reaction time, confusion, impaired balance and coordination and difficulty in problem solving.

Q:  Why should I buy a marijuana urine test?

A marijuana drug test that tests urine is a highly effective way to learn about recent drug use.  Our marijuana urine test is very simple and can be done in the home, at any time of the day.  A urine test is a common type of drug test and very inexpensive.  You can also test for more drugs at a time than you can with any of our other convenient at home drug tests.

Despite these advantages, a marijuana urine test may not suit your needs as well as a marijuana saliva test or a marijuana hair test.  If so, please check out our marijuana saliva test or marijuana hair test pages to find the drug test that best matches your needs!
