*Clinical studies confirmed that 99% of those individuals with drugs present in their urine tested positive with the First Check test. We recommend all positive screening results be sent to the laboratory for confirmation via gas chromatography/mass spectrometry(GC/MS), the gold standard in laboratory testing for most drugs.

Marijuana

What is it?

Marijuana is the dried leaves and flowers of the hemp (cannabis) plant.

Slang Terms:

Grass, dank, bud, zig zag, hydro, cannabis, bud, smoke, chronic, herb, reefer, pot, weed, ganja, dope, mary jane, skunk

Intoxicated Terms:

High, loaded, baked, roasted, buzzed, or stoned

How is it used?

Dried leaves are hand-rolled into cigarettes called joints or stuffed into hollowed-out cigars called blunts. Marijuana is also smoked in small pipes known as one-hitters or tooters, or in a larger water pipe called a bong.

Smoke is inhaled and held in the lungs as long as possible to maximize effects. Marijuana is also mixed into food and eaten or brewed with hot water into tea.

Sign of usage:

Dilated pupils, a lack of focus or slowed/changed speech.

Use of heavy perfumes or air fresheners to cover the distinctive odor of marijuana smoke.

Effects of usage:

Impaired brain functions resulting in the following:

Marijuana use can result in attention deficit, impaired memory, impaired learning, and difficulty with sensory experiences. Individual may also be unmotivated and experience impaired reaction time, motor skills, and ability to maintain and shift attention.

How long do the effects last?

Effects peak within 20 minutes and last 2-3 hours.

Effects of withdrawal:

Cravings, irritability, insomnia, anxiety

Adverse reactions:

Resembles a panic or anxiety attack.

Effects of prolonged usage:

Respiratory problems, nagging coughs, frequent chest colds, chronic bronchitis, and risk of pneumonia. Long term use can adversely affect the immune system and reproductive system.

Usage by 12th graders:

49% of High School seniors report having tried marijuana

32% of High School seniors report having used marijuana in the past year

22.4% of High School seniors report being current regular users of marijuana

Recent Developments:

Marijuana is being used in combination with other drugs of abuse and is a delivery medium for other drugs. Crack, psilocybin mushrooms, ketamine, and PCP are sometimes added to marijuana joints. Slang names for the combinations vary according to geographic locations around the country. Joints or blunts containing PCP are known as love boats, honey-dipped joints, happy sticks, sherms, or dust blunts. Dipping marijuana joints into other chemicals such as formaldehyde, embalming fluid, or formaldehyde mixed with PCP enhances the effects of marijuana and makes the joints and blunts burn longer. The PCP combination produces aggressive behavior in the users. Variations make marijuana smoking more unpredictable, particularly for novice users.

Cocaine

What is it?

Cocaine is a potent, addictive stimulant that directly affects the brain and central nervous system. This crystal powder is manufactured from the coca leaf. In its pure form, cocaine is a chemical known as cocaine hydrochloride. Crack cocaine is cocaine that has been cooked down with baking soda to form ammonia or sodium bicarbonate that is used by smoking.

Slang Terms:

Nose nachos, racehorse Charlie, yeyo, hooter, crank, blow, bad rock, bazooka, beam, Bernice, big C, blizzard, coca, blast beam, flake, nose candy. Crack is also referred to as freebase, ready rock, and gravel.

Intoxicated Terms:

Buzzed, high, getting a rush, freaked out

How is it used?

Cocaine can be inhaled or snorted through the nose or it can be injected directly into the blood stream. Crack cocaine can be smoked. The drug user uses baking soda with water and a hot flame to cook the cocaine into chunks or “rocks,” which are then broken into pieces that are smoked in a glass pipe. Many users mix other drugs with cocaine or crack to get what they consider a better high. When heroin and cocaine are used together, for example, it results in an immediate high and is also addictive at first time use.

Signs of usage:

There are physical and social signs to watch for in cocaine use. Physical signs include red, bloodshot eyes, runny nose, and frequent sniffling. The user may change eating habits and lose weight. There is often a change in sleeping habits, an increase in skipping school or flunking out of school, a distinct loss of interest in old activities, and a change of friends or groups. The user frequently needs money and will resort to stealing. The user will almost always be withdrawn, listless, and careless about personal appearance.

Effects of usage:

The effects of the drug depend on the way it is taken. The drug reaches the brain within seconds, creating a “rush.” When injected, the euphoric high happens more quickly and with more intensity. When inhaled or smoked, this rush takes place within several minutes. Tolerance is built up with use, so more of the drug has to be taken each time to experience the same effects.

How long do the effects last?

Effects peak within 20 minutes and last 2-3 hours. The high from cocaine lasts up to about 30 minutes and from crack, less than ten minutes. The euphoria makes this drug very addictive.

Effects of withdrawal:

Just as the intense emotional highs resulting from cocaine use are addictive, the lows after use can be devastating. This may depend on intensity of the hit and how the drug was taken. Fatigue and irritability also result. Intense cravings result from use because of the intensity and pleasure of the highs.

Adverse reactions:

Extreme psychological reactions can occur, including paranoia and excitability. The possibility of stroke and heart attack is a reality, especially when cocaine is mixed with another drug or with alcohol.

Effects of prolonged usage:

Cocaine poses risks of both physical and psychological addiction. There are numerous health consequences associated with cocaine use, including cardiac arrest and stroke due to reduction of blood flow to the heart and brain. Memory problems and abdominal problems are also risks. Alcohol and cocaine used together are a deadly combination and can cause sudden death. Snorting cocaine can actually rot teeth, damage nasal passages, and at the very least, cause nasal congestion. Lung problems and chest pain can result from smoking crack.

Use by age:

The average age of first use for cocaine is reported to be 19.5 years, and the most prevalent use by age is in young adults aged 18-25. However, the average age of those who finally receive treatment is mid-30’s.

Use by grade level:

1.2 % of eighth-graders
1.3 % of tenth-graders
2.1% of high school seniors
While cocaine users tend to be young, cocaine use is becoming more common by those who originally used it in their youth and are now in their 50s and older.

Recent Developments:

Cocaine use peaked in the 1970s and again in the mid- 1980s and 1990s. Though there is a reported decreased use with youth today, cocaine is a powerfully addictive drug with extremely dangerous health risks. Overall, young women are now using more crack than young men.

4 - If I test negative with a First Check Home Drug Test, does this guarantee I will test negative on other drug tests administered by a professional?

Many First Check® Home Drug testing products are more than 99 percent accurate in detecting specific drugs according to the designated cut-off levels. However, if a more sensitive test is administered, there is a chance of testing positive if drugs are present in urine.

Back to Top

5 - Is a white line considered a Preliminary Positive Result?

  • Yes. A white waxy looking line in the Drug Window (sometimes referred to as a “ghost line”) is considered a Preliminary Positive Result and should be sent into the lab for confirmatory testing.
  • A Negative Result can only be based on the appearance of a red or pink colored line in the Drug Window. Even if the line in the Drug Window is very faint, as long as there is some red or pink color to it, it is considered a Negative Result and should not be sent to the lab for confirmatory testing.

Back to Top

6 - What cut-off levels do First Check Home Drug Tests use for detecting drugs in urine?

  • The cut-off level for each drug varies (depending on the type of drug) and is measured in nanograms (ng/ml).
  •  Although First Check Home Drug Tests are designed to detect a very small amount of a drug in urine, if the amount is below the established cut-off level, you may test negative for that drug even though you may have taken the drug.

Drug Detection Time in Urine

Drug/Identifier Cut-off Level† Minimum Maximum
Marijuana (THC) 50 ng/ml 2 hours Up to 40+ days
Cocaine (COC) 300 ng/ml 1-4 hours 2-4 days
Methamphetamine (MET) 1000 ng/ml 2-7 hours 2-4 days
Amphetamines (AMP) 1000 ng/ml 2-7 hours 2-4 days
Ecstasy (MDMA) 500 ng/ml 2-7 hours 2-4 days
Opiates (heroin) (OPI) 2000 ng/ml 2 hours 2-3 days
Phencyclidine (PCP) 25 ng/ml 4-6 hours 7-14 days
Benzodiazepines (BZO) 300 ng/ml 2-7 hours 1-4 days
Methadone (MTD) 300 ng/ml 3-8 hours 1-3 days
Barbiturates (BAR) 300 ng/ml 2-4 hours 1-3 weeks
Tricyclic Antidepressants (TCA) 1000 ng/ml 8-12 hours 2-7 days
Oxycodone (OXY) 100 ng/ml 1-3 hours 1-2 days

† The Substance Abuse and Mental Health Services Agency (SAMHSA), has set “cut-off” levels when testing for marijuana, cocaine, methamphetamine, amphetamines, ecstasy, opiates, and PCP. First Check is manufactured to conform to those standards. Screening tests may not detect amounts of drugs in a urine sample that are below the cut-off level. Even though some level of drug may be present in a urine sample, the sample would still be considered Negative Result if the drug level is below the cut-off level.

7 - How soon after taking a drug can you detect it in urine with a First Check Home Drug Test and how long can a drug be detected in urine?

  • Most drugs can be detected in urine with a First Check Home Drug Test within a few hours after taking the drug; however this can vary depending on the type of drug taken, the amount taken, the frequency of use, and the metabolism of the person being tested.
  • Each drug is cleared by the body at different rates. Some drugs, for example marijuana, can stay in the body for up to several weeks after use.

Drug Detection Time in Urine

Drug/Identifier Cut-off Level† Minimum Maximum
Marijuana (THC) 50 ng/ml 2 hours Up to 40+ days
Cocaine (COC) 300 ng/ml 1-4 hours 2-4 days
Methamphetamine (MET) 1000 ng/ml 2-7 hours 2-4 days
Amphetamines (AMP) 1000 ng/ml 2-7 hours 2-4 days
Ecstasy (MDMA) 500 ng/ml 2-7 hours 2-4 days
Opiates (heroin) (OPI) 2000 ng/ml 2 hours 2-3 days
Phencyclidine (PCP) 25 ng/ml 4-6 hours 7-14 days
Benzodiazepines (BZO) 300 ng/ml 2-7 hours 1-4 days
Methadone (MTD) 300 ng/ml 3-8 hours 1-3 days
Barbiturates (BAR) 300 ng/ml 2-4 hours 1-3 weeks
Tricyclic Antidepressants (TCA) 1000 ng/ml 8-12 hours 2-7 days
Oxycodone (OXY) 100 ng/ml 1-3 hours 1-2 days

8 - Why don’t First Check Home Drug Tests use “zero” as the cut-off level for detecting drugs in urine?

First Check uses standard cut-off levels to help to reduce the likelihood of false-positive screening results which can occur when using a zero cut-off level.

Back to Top

9 - Are there any factors that can affect the test result?

  • Certain over-the-counter medications or prescription drugs may cross-react with the First Check Home Drug Test and cause a Preliminary Positive Result.
  • The test will only give accurate results on fresh human urine samples. Old or diluted urine samples may not be suitable for testing.
  • If you are testing someone else, keep in mind that First Check Home Drug Tests are only as accurate as the urine sample being tested. Samples can easily be “adulterated” (i.e., contaminated or tampered) with common household products such as bleach and other liquids if you’re not closely supervising the entire process.
  • This test provides a screening result only. It is not designed to determine the actual concentration of a drug, the level of intoxication nor is it to be used for legal purposes.

Drug Detection Time in Urine

Drug/Identifier Cut-off Level† Minimum Maximum
Marijuana (THC) 50 ng/ml 2 hours Up to 40+ days
Cocaine (COC) 300 ng/ml 1-4 hours 2-4 days
Methamphetamine (MET) 1000 ng/ml 2-7 hours 2-4 days
Amphetamines (AMP) 1000 ng/ml 2-7 hours 2-4 days
Ecstasy (MDMA) 500 ng/ml 2-7 hours 2-4 days
Opiates (heroin) (OPI) 2000 ng/ml 2 hours 2-3 days
Phencyclidine (PCP) 25 ng/ml 4-6 hours 7-14 days
Benzodiazepines (BZO) 300 ng/ml 2-7 hours 1-4 days
Methadone (MTD) 300 ng/ml 3-8 hours 1-3 days
Barbiturates (BAR) 300 ng/ml 2-4 hours 1-3 weeks
Tricyclic Antidepressants (TCA) 1000 ng/ml 8-12 hours 2-7 days
Oxycodone (OXY) 100 ng/ml 1-3 hours 1-2 days

Even though some level of drug may be present in a urine sample, the sample would still be considered Negative Result if the drug level is below the cut-off level.

Back to Top

10 - When is the best time to take the test?

  • Use first morning urine when possible as this urine tends to be the most concentrated urine of the day making it best for detecting any drugs that may be in the system.
  • However, First Check Home Drug Tests can be used any time of day.

Back to Top

11 - How soon can I read my results?

  • You can read your results after 5 minutes as long as a red or pink colored line has appeared next to the word Control or the letter C.
  • Disregard all results after 10 minutes.

Back to Top

12 - How do I know if the First Check Home Drug Test worked properly? What if I am unsure of the result?

  • The test is working properly as long as a red or pink colored line appears next to the word Control or the letter C (depending on the test you have purchased).
  •  The result is Negative when a red or pink colored line appears next to the word Drug or the drug abbreviation (depending on the test you have purchased).
  • The result is Preliminary Positive when NO line appears next to the word Drug or the drug abbreviation (depending on the test you have purchased).
  • If you have questions about your results call 1-888-788-5716 to speak with one of our First Check representatives.
  • If you are unsure about your results please re-test using a new First Check Home Drug Test.

Back to Top

13 - What is meant by a Preliminary Positive Result?

The First Check Home Drug Test is considered a “screening test.” We recommend all Preliminary Positive Results be sent to the laboratory for free confidential confirmatory testing. Gas chromatography/mass spectrometry (GC/MS) is considered the gold standard in laboratory testing for most drugs.

Back to Top

14 - The Drug Line is lighter than the Control Line. Does this mean some drug is present?

No. Any line next to the word Drug or the drug abbreviation (depending on the test you have purchased), no matter how dark or light, is considered a Negative Result and no further testing is required. It is possible that the intensity of the lines will vary among the drugs being tested for due to a variety of reasons such as; how diluted the urine is, the pH or protein level of the urine, or interference from a metabolite in the urine that closely resembles the drug.

Back to Top

15 - How accurate are First Check® Home Drug Tests?

Many First Check® Home Drug testing products are more than 99 percent accurate in detecting specific drugs in urine. The accuracy of the test depends on several factors such as how close to the cut-off level the drug is in your urine, how soon the test was administered after ingesting a drug, and how much of the drug was used or ingested.

Drug Detection Time in Urine

Drug/Identifier Cut-off Level† Minimum Maximum
Marijuana (THC) 50 ng/ml 2 hours Up to 40+ days
Cocaine (COC) 300 ng/ml 1-4 hours 2-4 days
Methamphetamine (MET) 1000 ng/ml 2-7 hours 2-4 days
Amphetamines (AMP) 1000 ng/ml 2-7 hours 2-4 days
Ecstasy (MDMA) 500 ng/ml 2-7 hours 2-4 days
Opiates (heroin) (OPI) 2000 ng/ml 2 hours 2-3 days
Phencyclidine (PCP) 25 ng/ml 4-6 hours 7-14 days
Benzodiazepines (BZO) 300 ng/ml 2-7 hours 1-4 days
Methadone (MTD) 300 ng/ml 3-8 hours 1-3 days
Barbiturates (BAR) 300 ng/ml 2-4 hours 1-3 weeks
