    In some circumstances, the drug test may report traces of illegal substances though none were taken.  This is referred to as a false positive and can be caused by the donor taking Ibuprofen, Marinol (generic name Dronabinol), Hemp-contain food products, Riboflavin, Bc or having diabetes, kidney or liver disease.  Because no test is 100% accurate, consider sending positive specimens to a lab for independent confirmation.

    When you need to check if someone is smoking marijuana, this test has a proven track record as the best in terms of price and quality.

    • The test is CLIA Waived indicating the test is certified accurate and designed to eliminate mistakes during home use.

There are some over-the-counter drugs that can cause false positives on Marijuana urine testing: Ibuprofen: (Advil®, Nuprin®, Motrin®, Excedrin IB®, etc); Naproxen (Aleve®); Riboflavin (B2, Hempseed Oil) and possibly some more

THC Marijuana Urine Drug Test Cassette Kit Instruction

Explanation Of The THC Drug Test (Marijuana)
THC marijuana (9-tetrahydrocannabinol) is the primary active ingredient in cannabinoids (marijuana). When ingested or smoked, it produces euphoric effects. Users have impairment of short-term memory and THC(Marijuana) use slows learning. Also, it may cause transient episodes of confusion, anxiety, or even toxic delirium. Long term, relatively heavy use may be associated with behavioral disorders. The peak effect of smoking THC (marijuana) occurs in 20-30 minutes and the duration is 90-120 minutes after one cigarette. Elevated levels of urinary metabolites are found within hours of exposure and remain detectable for 3-10 days after smoking. The main metabolite excreted in the urine is 11-nor- 9-tetrahydrocannabinol-9-carboxylic acid.
The THC / marijuana drug test is based on the principle of the highly specific immunochemical reactions between antigens and antibodies, which are used for the analysis of specific substances in biological fluids. The sensitivity is 50 ng/ml of THC marijuana.

FAQ about Marijuana:

Q: How long does marijuana stay in the user's body?
A: THC in marijuana is readily absorbed by fatty tissues in various organs. Generally, traces (metabolites) of THC can be detected by standard urine testing methods several days after a smoking session. However, in heavy, chronic users, traces can sometimes be detected for weeks after they have stopped using marijuana.

Q: Does using marijuana lead to other drugs?
A: Long-term studies of high school students and their patterns of drug use show that very few young people use other drugs without first trying marijuana, alcohol, or tobacco. Though few young people use cocaine, for example, the risk of doing so is much greater for youth who have tried marijuana than for those who have never tried it. While research has not fully explained this association, growing evidence suggests a combination of biological, social, and psychological factors are involved. Researchers are examining the possibility that long-term marijuana use may create changes in the brain that make a person more at risk of becoming addicted to other drugs, such as alcohol or cocaine. While many young people who use marijuana do not go on to use other drugs, further research is needed to determine who will be at greatest risk.

Q: How can I tell if my child has been using marijuana?
A: There are some signs you might be able to see. If someone is high on marijuana, he or she might seem dizzy and have trouble walking; seem silly and giggly for no reason; have very red, bloodshot eyes; and have a hard time remembering things that just happened.

Q: When the early effects fade, over a few hours, the user can become very sleepy.
A: Parents should be aware of changes in their child's behavior, although this may be difficult with teenagers. Parents should look for withdrawal, depression, fatigue, carelessness with grooming, hostility, and deteriorating relationships with family members and friends. In addition, changes in academic performance, increased absenteeism or truancy, lost interest in sports or other favorite activities, and changes in eating or sleeping habits could be related to drug use. However, these signs may also indicate problems other than use of drugs.

In addition, parents should be aware of signs of drugs and drug paraphernalia, including pipes and rolling papers; odor on clothes and in the bedroom; use of incense and other deodorizers; use of eye drops; posters, jewelry, etc, promoting drug use.
