It is extremely common to use pure CBD oil for anxiety disorders. Some people might find this contradictory because they assume that cannabis actually induces anxiety. But remember how we discussed the differences between CBD and THC? If you have ever felt anxious or panicked after smoking, there’s a good chance you were smoking a strain high in THC.
With so many companies popping up every day, we’ve done the hard work for you. We bring you the best CBD oil guide and the top 25 brands that made our list based on CBD oil quality, effectiveness, customer service and of course price. Please note, this article is updated constantly, so don’t forget come back from time to time to see the most updated information.
Based in Los Angeles, Calm by Wellness plans to be among the largest hemp-growing and CBD extraction facilities in the world by the end of 2019. The company sources their hemp from Colorado and uses clean CO2 technology to extract their CBD and other cannabinoids (no THC though!). The company is also GMP and ISO9001 food-grade manufacturer certified.

Cannabidiol, or CBD for short, is a natural phyto-cannabinoid (or plant-based chemical compound) found in cannabis plants, including hemp and marijuana. Unlike other cannabinoids — namely tetrahydrocannabinol, or THC — CBD does not produce any psychoactive effects, and will actually counteract these effects to a degree. CBD will induce feelings of sleepiness; for this reason, it can be an effective soporific for people who struggle to fall and/or remain asleep due to insomnia and other sleep disorders.
Amazon entered the retail grocery space by acquiring Whole Foods Market in 2017. Since then, Whole Foods Markets across the country have been slowly changing and their products are being incorporated into Amazon’s online grocery offerings. While you can find plenty of hemp-based products in the cosmetic, grocery, and wellness departments at Whole Foods, like their parent-company Amazon, Whole Foods still does not sell hemp-derived CBD oil.
Hemp being federally legal would be huge for the CBD industry, as CBD oil made from hemp extract (a plant that has very low amounts of THC) would be legal. A new, more available form of CBD would also allow for more research on the subject of cannabidiol, and perhaps the entire marijuana plant. More research brings the potential of coming closer to full legalization.
Historically, hemp could legally be grown and cultivated for academic research purposes only. However, the legality of hemp growth has changed in the past year. In April 2018, Sen. Mitch McConnell of Kentucky introduced the Hemp Farming Act of 2018, a piece of legislation that proposed legalizing all hemp products at the federal level. The act was incorporated in the 2018 United States Farm Bill, which passed in both the House and Senate in December 2018. Per the farm bill, industrial hemp will be descheduled as a federally controlled substance.
In 2014, President Obama signed into law the Agricultural Act of 2014. Section 7606 of the act, Legitimacy of Industrial Hemp Research, defines industrial hemp as distinct from marijuana. This authorizes institutions of higher education or state department’s of agriculture in states that legalized hemp cultivation to regulate and conduct research and pilot programs. Basically, it’s up to the states to regulate the growth per their own State Departments.
Non-THC CBD oils can be highly effective, and are suitable for employees who face random or routine drug tests. Our top pick for this category is the Medterra CBD Oil Tincture, which contains 99.6% CBD and MCT oil (also known as coconut oil extract) without any traces of THC. The oil is derived from hemp plants that are free of GMOs and pesticides, as well. All third-party testing results for the oil are accessible through Medterra’s official product page.
You can thin the CBD with terpenes, encapsulate it in dextrin, drive the terpenes off with heat, and use the now water-soluble CBD in water with an ultrasonic fogger/oil-diffuser. It won’t precipitate, but the level of solubility is pretty low even with encapsulation, think 100mg per 200ml. The evaporation rate of those units is somewhere like 50ml/hour, which works out to .83mg of CBD being vaporized a minute, or .14mg every 10 seconds. That’s a miniscule rate.
In short, CBD oils made from hemp must contain less than 0.3% THC – this is below the legal federal limit (and is why many CBD oil companies claim to be able to ‘legally ship to all 50 U.S. states’). In contrast, cannabis CBD oils (that you’d find in places like medical marijuana dispensaries) may have a much higher THC content, given that they are made from marijuana rather than hemp.
