Drug detection factors
The length of time that a drug is detectable in the system depends on a variety of factors, including:
- the type of test
- the existence of medical conditions
Drug detection times
Please use these figures as a guide only:
- Alcohol: 3-5 days in urine, 10-12 hours in blood
- Amphetamines: 1-3 days in urine and around 12 hours in blood
- Barbiturates: 2-4 days in urine and 1-2 days in blood
- Benzodiazepines: 3-6 weeks in urine and 2-3 days in blood
- Cannabis: 7-30 days in urine and up to 2 weeks in blood
- Cocaine: 3-4 days in urine and 1-2 days in blood
- Codeine: 1 day in urine and up to 12 hours in blood
- Heroin: 3-4 days in urine and up to 12 hours in blood
- LSD: 1-3 days in urine and up to 2-3 hours in blood
- MDMA (ecstasy): 3-4 days in urine and 1-2 days in blood
- Methamphetamine (crystal meth): 3-6 days in urine and 24 – 72 hours in blood
- Methadone: 3-4 days in urine and 24-36 hours in blood
- Morphine: 2-3 days in urine and 6-8 hours in blood
Drug detection in hair
Drugs or their metabolites may be detectable in hair. Hair grows at a rate of approximately 1cm per month so depending on the length of hair it may be possible to determine drug use over recent months.
This drug is commonly found in the form of a white powder, but many times mixed with other similar looking powder such as baking soda or baby powder to create artificial filler. Cocaine is a processed drug that is made from the leaves of the coca plant. Some enjoy a lighter effect of cocaine by chewing the raw coca leaf.
As a stimulant, cocaine is popular among people who need to stay up for a long time such as an overnight work shift or all night parties. It is also an appetite suppressant that can cause dangerous and rapid weight loss.
The United States government recognizes cocaine as a schedule 2 drug with high potential for abuse but less abuse potential than Schedule I drugs. They are likely to lead to severe psychological or physical dependence and are considered dangerous, and are tested in all 5 panel drug tests.
Amphetamines are usually found in pills and crushed by the user for snorting. Like cocaine, amphetamine is susceptible to artificial fillers to add weight to the drug. Amphetamine is a laboratory drug commonly found in ADHD and ADD treatment drugs such as Adderall and Ritalin.
Like cocaine, amphetamine is also a stimulant and appetite suppressant, but to a lesser extent. Instead of the energy rush of cocaine, amphetamines simply allow the user to stay awake, alert, and focused. It is a dangerous, but popular "study drug" commonly found among high school and college students.
It is considered a schedule 2 drug with high potential for abuse and potential for psychological or physical dependence. Although illegal recreationally, it is available by prescription.
Methamphetamine (part of Amphetamines)
Methamphetamine is a form of amphetamine with a similar chemical base, most commonly known as its nickname, "meth". Meth is found as a powder or in a crystallized form. Since most meth is made by illicit home laboratories, it is hard to establish a standard of composition or strength.
The user of meth experiences a sudden rush of euphoria and increased energy and focus. After the initial effects subside, the user now requires a larger amount to regain the same high. This dangerous addiction creates a strong and violent dependence. Over time, meth destroys dopamine receptors, making it impossible to feel pleasure.
Due to the dangerous effects and habit of meth, it is considered a schedule 2 drug along with cocaine and amphetamine. It is illegal, and a top target for law enforcement agents, and usually tested in a 5 panel drug test. There are medicinal uses for meth with a prescription, but these are rare and tightly regulated.
Opiates are processed from the opium poppy plant usually found in South-East Asia. The opiate base is used to create illicit drug such as heroin, as well as medicinal painkillers such as morphine.
Opiates are strictly a relaxer that reduces pain and increases euphoria in the user. Illegal versions of opiates such as heroin and opium can be smoked, snorted, or injected. Like meth, addiction to opiates is very strong, and can consumes one’s life. When injected, the shareable diseases transmitted introduce a new risk to using the drug.
Since there are legitimate uses for opiates in the medical field, different versions of it are scheduled differently by the Department of Drug Enforcement (DEA). Heroin is a schedule 1, but Vicodin, a prescribed painkiller made from opiate derivative, is a schedule 3 drug.
THC is naturally found exclusively in the marijuana plant and in a synthetic form as Marinol. Marijuana is found either in dried flower buds, processed into hash, or found is baked foods such as brownies and cookies. Users either smoke the dried buds and hash, or eat the edible baked goods.
Users of marijuana mostly smoke it to achieve a feeling of relaxation and euphoria, but anxiety and paranoia is possible. Although marijuana does not have a strong dependence factor, prolonged use can result in a variety of negative cognitive effects relating to space and time perceptions as well as a lack of motivation.
The Federal government recognizes marijuana as a schedule 1 drug with no medicinal uses, although many US states recognize medical uses and allow legal prescription of marijuana. Colorado and Washington have also legalized marijuana recreationally, but often still test for THC in a 5 panel drug test.
Phencyclidine is a synthetic chemical generally made in illegal laboratories or stolen from veterinary sources. It can be found either in a powder form or in a clear, yellowish liquid. Users can smoke, inject, snort, or take in the drug in a variety of different ways.
Legitimately made as an animal tranquilizer phencyclidine, also known as PCP or angel dust, is used recreationally to induce hallucinations and dangerous ‘out of body’ experiences. Severe cases of PCP use are contributed to prolonged states similar to schizophrenia.
Due to medical uses, Phencyclidine is considered a Schedule 2 substance with no legal use for humans. It is considered a very dangerous substance with detrimental effects. SAMHSA reports PCP related hospital visits increased by more than 400% from 2005-2011.
These are the most commonly abused and dangerous drugs that Mobile Health encourages employers to screen for during a 5 panel drug screen. From dangerous dependency related risks to cognitive deterioration, these drugs are a risk to the user and the workplace. A 5 panel drug test is designed to detect these substances, and allow employers to take appropriate decisions relating to enforce their drug free workplace.
Typically no one will watch you provide a urine specimen, this is done in private. Based on DOT regulations or Company policy some tests such as return to duty and follow-up will be direct observed tests which means the same sex collector will observe your urination. Also if your urine specimen temperature is out of range or if the collector finds something suspicious; a second collection will be completed with a same sex collector observing your urination. Less than five percent of all tests require the direct observation.
All drug tests come in the form of panels where each panel is a drug being tested. For example, a 5 panel drug test checks for 5 drugs, while a 10 panel drug screen checks for 10 drugs.
A standard 5 panel drug urine test is the drug test most frequently used by government agencies and private employers. A 5 panel drug test typically tests for commonly abused substances, including THC, Opiates, PCP, Cocaine, and Amphetamines. Mobile Health offers five panel drug testing at 6 New York City & Long Island locations.
For the majority of workplace drug tests, a 5 panel drug screen is used. In fact, this is the standard for the Federal governments Mandatory Guidelines for Workplace Drug Testing.
The Department of Transportation (DOT) also uses five panel urine drug tests. DOT truck drivers are required to undergo a drug test prior to employment, at least once randomly per year, after most accidents, and if reasonable suspicion exists that a driver is abusing drugs. The DOT 5 panel drug test checks for THC, Opiates, PCP, Cocaine, and Amphetamines.
Dilute means the urine specimen had more water then urine. This basically means that the donor consumed a large quantity of water before providing the urine specimen. Maybe the person drinks a lot of water, maybe they drank a lot of water on purpose in order to try and cheat on the test. A positive dilute is still a positive result. With a negative dilute result there may be suspicion. This is not a positive. Employers should have a provision in the drug free workplace policy for negative dilute results. This policy can state that the negative dilute is accepted as negative or that the employer requires the person to go back for another test. The individual going back for another test should be instructed to not drink any large quantity of water prior to this next test, perhaps even a supervisor should accompany the person for the second test.
There is no exact science for this and may depend on hair testing, oral fluid testing or urine drug testing. For hair testing it takes about a week. For oral fluid drug testing it can be just a few hours. For urine testing it can be from 4-5 to 8-12 hours. The exact time can be different from one individual to another and a lot of other are factors involved including which drug, how strong the drug is, the person’s metabolism, the persons weight and perhaps what the person has eaten or drank. Bottom line is if the individual uses illicit drugs, they will at some point show up in hair, oral fluid or urine.
