CBD and Drug Tests

CBD AND “ANTI-DRUG” TESTS

Many people regularly taking CBD, by inhaling it or through oils, wonder if cannabidiol has an influence on drug tests, particularly following a withdrawal of driving license. When taking blood or a urine test, it is the THC that is sought. CBD does not have the same molecular structure is not identified like THC, because CBD is non-psychoactive and legal. It should be noted that with a urine test that detects THC, such test has a very low reactivity with the non-psychotropes substances such as CBD. This is good news for consumers of CBD.

CBD oil contains much less THC (1/10 to 1/300) that cannabis said recreational. A person who consumes 1000 to 2000mg of CBD per day will absorb the equivalent of 3 to 6mg of THC. This very low THC proportion does not make it detectable, even if it is the case because some tests are not accurate on the substance or on the amount, this will represent a “false-positive” due to the non-THC metabolites components, which will be clearly identified by GC/MS, GC / mass spectrometry or HPLC, HPLC.


Note

Most of the research showed that a “joint” of with strong THC cannabis, contains about 40-50mg of THC, which will give a positive result in tests, up to two days. But for regular smokers this same positive result can last for weeks, according to:

  • How many and how often cannabis is used
  • The metabolism of each person
  • The method of administration (smoked or absorbed)
  • other factors such as taking certain medications, or the general State of health.

This article contains non-exhaustive general information, also the standards of tests and analyses is highly variable depending on the country, regions and cantons (Switzerland), we invite you, if you are concerned by the subject of a positive test, to study this more in detail with your doctor or a legal reference in your geographic area.
