Cannabidiol, commonly referred to by the much easier to spell acronym CBD, contains many, but not all, of the health benefits of the Cannabis sativa plant. Like other marijuana products, a number of strains exist which have varying intensities and effects.
CBDs major difference from marijuana lies in the lower to non-existent amount of THC (tetrahydrocannabinol) in the products. Because THC gives the psychotropic properties of the hemp cannabis plants, it’s the feature more closely scrutinized and controlled by drug enforcement.
Separating the CBD from the THC allows CBD products to be available more widely and legally than THC products. However, because they come from the same plant and are linked chemically, the concern over what a marijuana drug test looks for and if it will find CBD use becomes relevant.
Though CBD has shown many positive effects in treating ailments, the entourage effect limits the end result. This effect, which is not currently well understood, indicates that CBD and THC interact with each other in a way that apart they do not.
The potency of effects for both seems to grow when they accompany each other, hence entourage effect. While new research has been slow because of restrictions, it’s hoped that in the future, this effect will be better understood and more potent forms of CBD will become available.
CBD oil has broad uses for treating a variety of ailments. The effect of CBD as a treatment largely come from interaction with neurotransmitters. The market for legal marijuana products has grown and is projected to be worth more than $60 billion within ten years.
We have given some more exhaustive lists of what CBD treats already. Generally speaking, anything caused by abnormal neurotransmitters shows improvement. The second category contains appetite and digestive relief which comes from aiding of amino acids in the GI system.
CBD products get marketed through oils, crystals, capsules, and balms. Like any other pharmaceutical, these come in different sizes of dosage which can be scaled up and down via the packaging and then controlled further by individuals. Controls can be done through frequency or multiples of the dosages provided.
Calculations on effect from body weight, age, and so on have not been easy to research, so many products are provided with recommendations on how to scale rather than flat instructions.
Understanding a Marijuana Drug Test
Marijuana drug test standards have been in place for years. Even though the legality of marijuana products such as CBD oil has shifted, the regulations regarding drug tests have not. This creates a sense of panic because there exists no specific ruling that prevents a company operating under Division of Workplace Programs oversight from refusing employment or firing a person that tests positive for marijuana usage.
How it Works
Marijana drug test protocols utilize antibodies to detect THC as well as its metabolite (11-n0r-THCCOOH). The antibodies attach to THC which then show for the drug screeners. The more THC in the system, the more likely there will be a hit on the test.
What the antibodies do not look for or attach to is CBD. Generally, a product with low to no concentration of THC should prevent the attachment of antibodies, and therefore yield a negative result on a test in urine or blood.
Blood tests tend to be the most accurate. Hair tests are less accurate but can detect usage and build-ups for a longer time frame (six months). Urine tests are the most common because they are cheaper and cover a middle window of a few weeks.
CBD oil with little to no (less than 0.5% THC or less) will have a hard time giving a positive result unless large quantities are used. By large quantities, we mean 2000 mg or more daily.
Even so, at 2000 mg and above of daily use, the result will only give a false positive. GC/MS (gas chromatography/mass spectrometry) tests will be used to verify the result and will show negative because they are designed to find THC, not CBD or other cannabinoids.
Unless the CBD product company has a problem with their refining process or is behaving unethically in what they list as the THC content of their products, there is little to fear with medicinal use of products.
To better understand exactly what each type of marijuana drug test looks for, and why those tests will not be an issue for CBD use, the following gets into the gritty details.
Several different types of tests exist, and each has a different reliability and cost. Generally, the lower cost tests give faster results but are also more prone to giving incomplete results. Depending on what level of scrutiny a company wants to put out, tests can cost over $100 to run.
Tests from least accurate to most follow this path:
Tests can be performed using immunoassay techniques, gas chromatography or a combination of gas chromatography/mass spectrometry (GC/MS). These different methods offer variable precision as well. Much like the substance being tested, the more precise tests take more time and cost more.
Originally developed for use by parents concerned about what children and teens may be up to, these marijuana drug tests use dipsticks and color-strips of the Immunoassay variety.
These tests don’t hold much sway in a legal sense. They’re used as precursors to determine if further testing will be worthwhile. Basically, these tests are used to rule out use, not rule in use.
Dipstick tests commonly require a second sample. Cup tests with built-in strips are designed to indicate in one area and keep the other portion of the specimens for review in a lab using other methods.
Instant tests are exclusively urine related.
Urine-based marijuana drug tests take a sample, often collected in a sealed plastic cup and done up with tamper evident tape, and splits it into two portions. The first portion is screened using immunoassay analyzers. If there is a positive, a confirmation is obtained through GC/MS using the second portion.
Saliva-based marijuana drug tests can only detect usage of substances within a narrow timeframe. For marijuana products, this is no more than 24 hours unless a person is a heavy user, which can create a build up that can last a little longer. Saliva tests work like urine tests with immunoassay analysis first and GC/MS for confirmation of any positive hit on the first portion.
Workplaces seem to be doing more saliva testing because it’s better for detecting on the job use, rather than after-work recreational use. Management can collect samples quickly and without numerous pieces of specialized equipment. Together these conveniences are backed up by saliva being a strong test with a middle degree of accuracy in the spectrum.
Hair based marijuana drug tests have a high degree of accuracy, and they also have a high retention time. The highest retention time because metabolites get deposited into hair after going through the bloodstream.
Hair tests measure for roughly 90 days which is measured in 1 and 1/2 inch amounts from the scalp. A hair test cuts the hair near the scalp and then liquifies the hair to be subjected to GC/MS testing.
Hair tests are more expensive than urine tests so they normally are only done in high volume or high-value industries such as the casino industry.
Blood used for a marijuana drug test works on the same principles as other tests but have a higher degree of accuracy because of the purity of samples. Other tests take a substance and then process it to some extent to be fed into machines and devices. Most commonly these are liquids and gasses, which blood already is.
Blood testing doesn’t occur often because taking blood is viewed as more obtrusive than other methods. Because blood is a volatile fluid which is considered a bio-hazard, it has to be collected by trained professionals. Job sites are often underequipped for this kind of testing.
These biochemical marijuana drug test protocols measure concentrations and presence of substances. They do this through use of antibodies. Immunoassay tests process blood and urine commonly.
Binding of antibodies to specific molecules shows a color change. The more of a substance in a sample, the more color concentration.
These tests have a few issues with false positives and negatives. These occur from other drug interactions and storage temperatures for samples. Outside of a small temperature window, samples can become non-viable.
Gas Chromatography/Mass Spectrometry
For this marijuana drug test, a sample gets separated into extracts and component parts. Inert gas forces samples through columns which measures the temperatures and affinity of the chemicals within. The time a sample takes to separate gets measured and cataloged in a process called retention.
Every substance has a unique retention time so it can be used to create a complete picture of what a sample contains, no matter how many elements are in a sample.
Next, the MS portion provides information on the exact molecular weight and components of each sample.
To accomplish this, samples are bombarded by electrons in a mass spectrometer which breaks up the molecules into fragments. The fragmentation patterns are measured and compared to known results which are reproducible.
These tests can determine why a false positive or a false negative occurred by finding exactly what other compounds may have caused binding issues with immunoassay tests.
Given the number of devices and the precise nature of the reports, it’s easy to see why this gets expensive and takes time. Because of the widespread demand for marijuana drug test protocols in workplaces, the cheaper methods are by far more common.
The Substance Abuse and Mental Health Services Administration (SAMHSA) provides regulations and controls for marijuana drug test administration. Their website on marijuana offers a lot of cautions, but these are aimed at THC rich products and ignores CBD products.
Lawsuits and trends have been pushing employers to reconsider drug testing policies in regard to marijuana products. Occupational Health and Safety wrote about the general weakening of enforcement over a year ago. While they cautioned employers that this would have a negative that would hurt business, the trend continues.
2017 showed several court rulings against employers firing for approved medicinal product use. Though encouraging, this doesn’t mean that drug testing will stop looking for THC and will not expand under the current administration. The odds do seem low, however.
Though a test does exist to identify CBD, the Beam test, it’s not currently used. The test works like an Immunoassay test and is used to determine the purity of products when being manufactured. Though it could be used to detect regular drug use, it has not been developed in the way that THC tests have.
