In terms of coverage, urine testing is by far the most effective technique. This painless and accessible testing method can detect a huge range of substances and compounds, while it will also deliver results within a matter of days (and in some cases instantly).
Blood, hair and perspiration testing are similarly restricted in terms of the substances that they can detect, which at least partially explains why urine is the preferred biological specimen for employees.
What Substances are Screened During a Drugs Test?
Most interestingly, different testing methods can be used to detect a variable range of substances, so employers will often select a viable technique that will help them to achieve their precise objectives.
THC is one of the most commonly recognised compounds in this respect, as it confirms that the subject has used cannabis within a detectable period (which may span a relatively long time in this instance as the substance is fat soluble and capable of being stored in cells).
From an employer perspective, employers also have a duty to use drug testing methods responsibly and appropriately at all times. This means limiting mandatory testing to the type of staff members mentioned above, while also refraining from targeting individuals unfairly.
Being inadvertently exposed to THC by being around people who consume marijuana regularly. More likely to be picked up on a hair test rather than urine or blood, this can still cause a false positive on a drug test.
Earlier, we mentioned that CBD is the most accurate form of drug testing. Based on this, you might be wondering if CBD shows up on a blood test.
Marijuana and hemp are both varieties of cannabis. The difference between the two is how much THC is present:
Accidental THC contamination
Does your daily CBD capsule mean you’ll fail your next drug test? Fear not; we’re here to answer any questions you may have.
Marijuana – Cannabis that contains more than 0.2% THC;
Hemp – Cannabis that contains less than 0.2% THC.
Different types of cannabis drug tests will have different thresholds for the amount of THC that they can detect. You are most likely to receive a cannabis urine test, but you could also be tested for the presence of THC in your saliva, sweat, hair or blood.
A number of UK-based test manufacturers offer free CBD drug tests, with other purchases. We’d recommend keeping a few on hand, if you’re unsure about passing a drug test.
Marijuana is the bud of the flower from the Cannabis Sativa or Cannabis Indica plant, which is used recreationally or for medical purposes, most commonly by smoking it. CBD is not hemp either, hemp is from Cannabis Sativa L plants. CBD is a chemical compound that can be extracted from any of these three plant types, however, the hemp plants produce more extractable CBD than their marijuana counterparts.

So, does CBD show up on a drug test?
– Some CBD product manufacturers have been known to make dubious claims about the health and medical benefits. The THC and CBD content stated on the label may differ from the actual contents.
Firstly, there are many different types of drug test analysis, one of which is known as Gas Chromatography-Mass Spectrometry, which is one of the only tests which could present a positive for CBD and THC at low levels. This testing requires the adding of a chemical agent to the sample in order to identify which drugs have been consumed, which is a process known as derivatization. The agents, and later the reagents, provide acidic conditions within which the CBD is able to convert into THC, which would then produce a positive result for a CBD user to make them appear as a regular cannabis user.
– You can’t know for sure, but marijuana-derived CBD contains higher levels of THC.
