Marijuana usage detection is fast, easy and accurate with our urine test cassette. Marijuana urine cassette has a sensitivity/cut-off level of 50 ng/ml in accordance to SAMHSA standards. You just put a few drops of urine into the cassette and read the test result in several minutes. One line means positive (Marijuana metabolites detected), two lines negative, even a very faint line shows a negative marijuana test result.
Detection times for marijuana usage vary depending on the drug potency, tolerance, and health condition, fluid intake at time of test, method and frequency of marijuana use. It is usually not more than 15-20 days for chronic users and 3-5 days for occasional smokers. People with overweight keep THC traces longer, as marijuana metabolites are fat soluble.

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
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
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;
Clothing, posters, jewelry, etc, promoting drug use.
