Generally, CBD oil is made by combining an extract with a carrier fluid or oil. This question is best answered by looking at how the CBD oil was extracted. CBD oil can be extracted using CO2 systems or by using chemical solvents. Both methods produce a CBD oil byproduct that is then combined with a fluid like MCT oil, coconut oil, or olive oil so that it can be delivered to the body. Always check to make sure you know the CBD content of the products you purchase.
The first step to finding your correct CBD dosage is getting as much information as you can about the product you’re using. What is the concentration of CBD? Are there third-party lab tests that can confirm that? The CBD industry is still mainly a grassroots therapeutic movement, and as such, largely unregulated. Concentration and purity levels can differ greatly depending on the manufacturing process.
When buying industrial hemp CBD, i.e. everything you see outside of a state-licensed dispensary, all bets are off. Because the legality of industrial hemp is in flux, companies that use hemp CBD operate in a gray market with no oversight. Nick Mosely, Chief Science Officer of a testing lab in Washington explained that “everything currently on the market for interstate CBD sales is unregulated.” And product labels can be wildly different from what's actually contained in the product. Multiple studies of CBD oil sold online have repeatedly exposed brands that misrepresent purity and CBD dosage levels.
With the market of medical marijuana and CBD (Cannabidiol) growing, it is important to know why something is legal and what exactly is illegal. It is also important to understand the laws around the importation of Hemp (which is legal to import) versus the States, not federal, laws that have legalized marijuana. This way you can purchase and consume with the good faith of knowing you are within your legal rights.
While researchers are calling for more robust studies on the role of CBD on mood disorders, there is promising research that points to CBD’s role as an anxiolytic – which means it has anti-anxiety effects. Another study showed CBD to have antidepressant effects comparable to those of the prescription antidepressant Imipramine. We noted above that CBD increases levels of glutamate and serotonin – and it’s these same neurotransmitters that play a crucial role in mood regulation.
Being a hyperaccumulator also has drawbacks: If a hemp plant that is used in production of CBD oil was cultivated in a land that is rich in heavy metals such as mercury and lead, the resulting oils will also reflect the amount of heavy metals absorbed by the plant, making it unsafe for humans to consume, especially children or others who are extremely vulnerable to toxins.
In order to account for the low CBD content of these hemp plants, manufacturers have to process large volumes of raw material at a time, with the idea of extracting just enough CBD so that they can label their product as a “CBD oil.” While this method is fine in theory, what ultimately ends up happening (unless the manufacturer’s extraction methods are state of the art), is that traces of chemicals cane end up being left over in the final product. These chemicals can potentially contain harsh solvents such as butane, hexane, and propylene glycol, which has been known to break down into carcinogenic (cancer-causing) compounds like formaldehyde and acetaldehyde.
This may seem like a repeat of an earlier question, but while that question related to concentration of CBD in the product, this is simply a question of how much you’re getting in total. Most bottles are labeled in a similar way – “1,000mg CBD Oil” or “1,000mg Hemp Extract” – which generally means the entire bottle contains a total of 1,000mg of CBD.
