Thanks to today’s screening technology, drug testing of cannabis users is much quicker, easier, dependable and inexpensive, and the results are lightning fast. In fact, the screening technology ensures that the most common techniques to cheat the drug test — dilution and sample swapping — are thwarted.
There are all kinds of drug tests that can determine if a person has cannabis in their system:
— Blood
— Hair
— Saliva
— Urine
Each testing method has its own way of identifying whether or not you have cannabis in your system as well as its own measure of precision. The most consistent and inexpensive drug testing option is the urine test. In fact, the test can determine if you smoked cannabis within the last 30 days.
The Difference in Hair, Saliva and Urine Samples in Cannabis Drug Testing Kits
If you want a cannabis drug testing kit, you’ll be delighted to know there are individual kits that can use either a saliva or urine sample. The test will provide immediate results and can determine if the use of cannabis is recent and how significant its use is. While both the saliva and urine tests are fairly accurate, the urine test is less costly than the saliva test. Our 7 drug Saliva Drug Test detects cannabis and six other drugs. It’s probably one of the best saliva drug tests on the market in the UK now.
On top of that, the saliva test can only detect cannabis for a short period of time after it’s been used — up to 24 hours after use. Remember, the urine cannabis test can detect the drug if it was used in the last 30 days.
Another worthwhile option in cannabis testing is the hair analysis. It can detect cannabis usage within the last 90 days because the residue entrenches itself in the hair. The results for this test can take between five and seven days. If you’re looking to find out if a person has smoked cannabis within the last three months, this is the test that can do it.
How to Carry Out the Urine Cannabis Drug Test
Now, how does the cannabis drug test work? All you do is pee in a cup and use a dropper to put several urine drops in to the testing well. After that, you just need to wait five minutes for the results. A negative result comes in the form of a line. No line means a person is positive for cannabis use.
What Factors Affect Cannabis Levels in the Body
Again, the urine test can detect cannabis for up to 30 days after its last use. So, if you use cannabis, you need to remember that is stays in the body much longer than any other drug. It’s possible that a sampling of cannabis won’t be measurable in a urine sample in roughly a week. However, this isn’t always the case.
There are several factors that affect the cannabis levels such as the body’s fat levels. The body stores cannabis in the fat cells, which means an obese person will have detectable levels of cannabis longer than a fit, muscular person.
What are the other factors that affect how long cannabis is detectable in the body? They include:
— Total body mass
— Regularity of cannabis use
— Length of time of cannabis use
— Cannabis strength (if high quantities of THC are found in the drug, the more powerful the drug)
Limitations of Cannabis Drug Tests
While cannabis drug tests are useful tools, they have limitations worth noting. For instance, these tests can’t determine exactly when cannabis was used or how much was consumed. They also can’t measure impairment levels.
False positives can occur, though rarely. Certain medications, foods, or supplements might trigger a positive result. For example, hemp seed oil or CBD products containing trace amounts of THC could potentially cause a positive test.
It’s crucial to understand that a positive test doesn’t necessarily mean recent use or impairment. THC can linger in the body long after its effects have worn off, especially in frequent users.
For employers or organisations conducting drug tests, it’s wise to pair testing with clear policies and open communication. Consider the specific needs of your situation when choosing a testing method. Remember, while these tests provide valuable information, they’re just one piece of a larger picture.
