Spruce was founded by Tony Spencer, who had a clear mission for his company—give people access to safe and effective lab-grade, hemp-based CBD. Spencer realized that many other CBD oils on the market were low-potency and simply didn’t work. “We have a lot of customers in pain who have wasted money on CBD products in the past that didn’t work for them,” remarks Spruce on their website.
People taking other medications: When side effects are reported, it’s often by this group. CBD appears to have a similar effect to grapefruit on the liver’s ability to metabolize certain drugs, which can lead to adverse side effects. Generally, if a medication has a grapefruit warning, you should avoid taking CBD. Although, if you are on any medication you should talk to your doctor before starting CBD, to ensure you won’t expect any negative interactions.
Hemp-derived CBD products were made federally legal in December 2018 with the signing of the 2018 Farm Bill. However, several states still have laws in place that restrict the sale and possession of these products. Most companies selling CBD oil are shipping to all 50 states. You should consult your local laws or an attorney in your area if you have concerns about legalities.
Along with PureKana and CW Hemp, I would say that Green Roads CBD oil probably rounds out the top 3 most popular hemp companies selling online, and that would generally translate to status as the “best CBD oil,” right? They have an incredible web presence, and in fact run a really great blog that you should keep up with if you’re interested in the latest CBD news, trends, etc. They’re also big into offering loads of different product, including pre-dosed pens called “Daily Doses,” CBD terpenes, edibles, and even potent CBD concentrates that you can dab (I don’t have a dab rig myself, but I have friends who say the potency is incredible). Honestly, you’ve just got to check out their website in order to get a better idea of the huge range of products they’ve got — all of which are of the highest quality.  
Since 2014, NuLeaf Naturals – our Editor’s Pick – has been committed to creating high-quality CBD oil products. As one of the oldest and most reviewed companies in the industry, NuLeaf Naturals has established themselves as a trustworthy CBD manufacturer. All of their products are tested by third party labs and their cannabinoid profile is impressive. They offer a unique range of concentrations for their organic CBD products ranging from 240mg to 4,850mg.
CBD Essence is another brand we’ve had plenty of experience with over the past 18 months or so, and my partner particularly likes his 600 mg Medicinal Grade tincture for quickly easing her anxiety. I haven’t tried them so much for may pain, but I do recall that a 30 mg dose was quite effective the last time I did take it. Also, the main reason they’re this high up on our list is because they’re a fair amount cheaper than Elixinol and PureKana. Their tinctures come in larger 2 oz bottles, but on a CBD-per-mg basis they’re about 20% less expensive than other top-quality brands.
Vape Pens – Perhaps the easiest way to get the CBD Oil into your body is through a vape pen. A vape pen is about the size of an ink pen but has a CBD oil cartridge with a heating element. Many people like vape pens because there is very little in the way of odor after using it and it allows for a lot of discretion because it can be pulled out of your pocket and used on demand.

You should only use CBD products if you are willing to accept at least some risk of testing positive on a drug test. Not everyone who uses hemp-derived CBD oil tests positive. But it does happen. The risk of testing positive is lower if you’re using a broad spectrum or isolate product. These products have non-detectable levels of THC based on manufacturer testing.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
