In 2006, a group of researchers studying the potential benefits of CBD in treating psychosis and anxiety, looked at several studies of CBD oil’s safety and summarized their findings in a paper published by the Brazilian Journal of Medical and Biological Research. Noting that CBD safety was first proven through animal research, the scientists added:
Transparency: cbdMD seems to be going through a transition with their third-party testing practices. Until recently, they only released a lab report for the CBD concentrate they use for all their products, but would not show potency testing for individual products. That seems to be changing. Currently, the only lab report on the website is for their concentrate (and it’s over a year old). But if you contact customer service, they’ll send you a lab report for any product. 
In fact, not only will CBD not make you high, it has been proven to counteract the psychoactivity of THC. This property makes CBD highly useful as a medical treatment for a wide range of conditions. In terms of the CBD products you can buy, the amount of THC present varies from none at all in a pure CBD Isolate to a minimal amount (less than 0.3%) in a Full-Spectrum CBD product.
CannabiGold’s unique selling point is not its oil, however, but its method of application. A common customer issue is droppers leaking because, when the highly viscous oil gets in the rim of a conventional dropper, it is not easy to close the bottle tightly anymore. By listening to their customers and conducting research and testing in their state-of-the-art facilities, the R&D team at CannabiGold developed a precise dropper technology that would allow 10g of CBD oil to be delivered in 400 micro drops, one at a time.

Really interesting reading all of the comments. I started using hemp oil capsules about 5 weeks ago mainly to treat aches and pains. I feel though like i’ve been going slightly mad, this is virtually impossible for me to describe, although i’ve been extremely happy, jokey etc, like everyone in the world is my best friend, my mind though is not at all right, everywhere I’ve been including familiar places like my own home seem so different, I almost feel like I’m looking at myself from a distance, I wish I could explain it better but it’s impossible to do so. I’m just on another planet. I’ve had stomach problems and I’m really off food, I’ve always been a hungry guy but not at the moment. I’m sure this product is fantastic for most people but sadly it doesn’t seem to suit me, I took my last capsule this morning, it suddenly hit me that is was the hemp causing the change in me. I’ll see what happens in the next few days. best wishes to everyone, like I said, everyone is my best friend at the moment.

But because all these products are illegal according to the federal government, cannabis advocates are cautious. “By and large, the federal government is looking the other way,” says Paul Armentano, deputy director of the Washington, DC–based National Organization for the Reform of Marijuana Laws (NORML), but until federal laws are changed, “this administration or a future one could crack down on people who produce, manufacture, or use CBD, and the law would be on its side.”
Within just one hour of watching an American television program, it’s likely you’ll see at least one ad for an antidepressant or heart medication, in which half of the commercial is spent rapidly listing dozens of possible side effects to consider before taking the medicine. In an in-depth study conducted in 2011, researchers found that out of thousands of medication labels analyzed, the average pharmaceutical carried over 70 listed side effects.
Realistically, you’re going to be looking at a minimum dose of about 40mg CBD if you want to feel effects, at least that’s in my experience. That said, I’ve noticed that dosing can be kind of sensitive – if I take over about 80mg, it seems to start effecting me negatively while a 40-50 mg dose works wonders for me joint pain and sleep. Just my two cents. Best of luck
