Third-Party Testing: Once a CBD oil is manufactured, CBD oil companies will often submit their products for third-party tests, which are conducted by non-company personnel to ensure the product is safe for public consumption and meets quality standards.CBD oils should always be accompanied with information about third-party tests; best practice is to avoid oils that do not supply these details.
It’s also important to select CBD oil products based on your concentration preferences. Some forms of CBD oil – such as vapors and tinctures – normally have higher-than-average concentrations, whereas sprays and topicals tend to have lower concentrations. Remember: higher concentration means more pronounced effects, but not necessarily mean higher quality.
Los Angeles-based PureKana stresses that it extracts the CBD oil for its products from hemp plants that have been cultivated without the use of herbicides, pesticides or other agro-industrial chemicals that may impact upon crops. What’s more, the company states, no solvents go into the extraction process other than carbon dioxide. And to further put potential customers’ minds at rest, PureKana presents the results of third-party testing of its CBD oil tincture on its website – a welcome nod to transparency. That tincture can be found in the company’s own blend of CBD oil drops – the three varieties of which have elicited highly complimentary reviews from users – as well as its capsules and cooling topical ointment. Meanwhile, for anyone with a sweet tooth, PureKana’s CBD isolate-containing gummy bears may just do the trick.
First, a little background. Industrial hemp was legal in the United States until Congress passed the Marihuana Tax Act in 1937. ("Some of our early presidents grew hemp," notes Sarah Lee Gossett Parrish, a cannabis industry attorney based in Oklahoma.) Nearly 80 years later, the 2014 Farm Bill took the position that states can regulate the production of hemp and, as a result, CBD. Then last year, President Trump signed a new Farm Bill that made it federally legal to grow hemp.
The color of CBD oil drops can range from clear or slightly golden, to a dark brown almost black. Several factors determine the finished product color, including the type of CBD extract, the extraction method used, the carrier oil used, and additional ingredients. Full spectrum (whole plant) extracts tend to be darker in color, whereas isolates tend to be more transparent.

Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.
Insomnia: The anxiety-alleviating and sleep-prolonging qualities of CBD oil make it a good option for many people with insomnia. Those who experience insomnia due to pain or discomfort may also find that using CBD oil alleviates their physical symptoms to a noticeable extent. CBD oil may also promote daytime wakefulness when taken in small amounts; people with insomnia can use it as a pick-me-up if they feel excessively tired due to lack of restful sleep.
And now, onto the thorny issue of legality. The simple answer to the question is yes — if it is extracted from hemp. The 2014 Farm Bill established guidelines for growing hemp in the U.S. legally. This so-called “industrial hemp” refers to both hemp and hemp products which come from cannabis plants with less than 0.3 percent THC and are grown by a state-licensed farmer.
