The cannabis plant itself is a soil-cleaning plant, meaning it will suck up all kinds of nasty stuff from the ground. Primarily if grown in a contaminated area. The best way to ensure the CBD oil you buy is safe is to make sure it's been third-party tested. Virtually all this means is that the test results will be unbiased and that any product that has gone through this process will have a certificate of analysis (COA) so you know it contains what it says on the label (and doesn't have anything extra you 100% don't want, like heavy metals or contaminants)
A COA is only given to labs to labs that are accredited testing labs. These labs must have the correct equipment and methods for testing cannabinoids.
The lab report, aka the COA, should always contain the following information.
CBD oil, CBD capsules, or any CBD based product for that matter should always have an accurate reporting of how much CBD per bottle/mg/ml/capsule (depending on the form of the product, of course)
For example, if there is a 150mg bottle of CBD that is 30ml, that would give you 5mg of CBD per ml. (divide the mg by the ml to get the amount of CBD per ml)
There are approximately 20 drops per ml, so to get the CBD content per drop, you would then divide the 5mg by 20. Which would give you 0.25mg per drop. (which, BTW, isn't very much at all.)
Once you know how big of a dosage your dog needs, you can then use the math above to help give you an accurate understanding of how many drops of ml they will need.
However, the amount of CBD per ml in the bottle will be known as the reported value. In the COA, the value found by the third-party las needs to be within 10% of the declared value on the label.
For both hemp CBD products and medical cannabis products, they will always require an accurate THC content reading. Even if the product is THC FREE product, this will still need to be listed and tested. (to prove there is no THC)
Many CBD products upon testing were found to contain high levels of THC, although they were labeled as "Hemp Oil". For a dog, this can be quite dangerous if there are high THC levels. So far, research reports that a minimal amount of THC is acceptable. However, large unmeasured amounts can be fatal in some cases.
For CBD wellness products, the THC content should be 0.2% or lower, which by the way, isn't nearly enough to cause any intoxication at regular doses. (unless you give them a ridiculous amount of CBD)
If the product is a full or broad-spectrum oil, it means that it will contain at least some minor cannabinoids in trace amounts alongside CBD. Minor cannabinoids are things like CBN, CBG, CBC, CBDA, CBDV, THCA. For a better overall result, the more cannabinoids, the better!
Typically these won't be shown on test results unless the manufacture tests for them precisely, even when measured. Depending on the kind of equipment the independent lab has, it can be quite challenging to get the exact amount of terpenes. In this case, you will often see it noted as "rich in Y or X Terpene."
SOLVENT RESIDUE, CONTAMINANT, AND HEAVY METALS
The lab should ALWAYS test for these things, as these will be the critical factors in the oil doing more harm than good. These things can be present in the oil due to growing conditions (soil, pesticides) and the extraction method used to obtain the CBD extract.
WHERE TO FIND THE COA FOR A CBD OIL
Most websites you will find will have the COSA lab reports for their products listed online or as downloadable PDF's. You might see them in the product description or possibly on the front page. You can always request this before purchase; never be afraid to ask.
Some local or independent products may not have a COA, and if you are planning on using them, I would always recommend getting them tested first. Better safe than sorry!
