Based on to Mayo clinic’s analysis (done by Doctor Brent A. Bauer) a serious problem may appears because of possible inaccuracy with the label’s information about purity and dosage of CBD in products. A current analysis of almost one hundred CBD products purchased online showed that more than a 25% of the products contained less CBD than labeled or does not have it at all. At the same time, 20% products have THC in illegal concertation. So, innocent people can be in trouble with regular drug test.
As with any emerging industry, you must be careful. Hemp oil products can vary in quality and potency, dependent on producer. It is important that it is correctly analyzed to guarantee benefits as well as ensuring it is free from harmful toxins. As such, you should know what to check before purchasing any hemp oil products.
The first thing you want to check on a COA is that the company who performed the lab test is not the same company who is selling the product. This is called a ‘third party’ test and it is to ensure transparency in the results. If it was only tested by the company selling the product, there could be bias in the report.
Listing the cannabinoids which were detected as well as their concentration is probably the most important section of the COA because it tells consumers exactly which cannabinoids are present and at what potency. ‘ND’ stands for ‘non-detect’ meaning there was such a miniscule amount, if any, in the sample that the laboratory instruments could not detect it. Essentially, this means it is not present in the product.
THC-Free broad-spectrum hemp oils should have CBD, other cannabinoids such as CBG or CBN, but non-detect levels of THC. Full spectrum hemp extracts should have many cannabinoids including D9-THC, if the THC weight % is below 0.3%.
