All CBD products start out the same way: as an extract from the leaves and flowers of cannabis plants. At Green Roads, we only extract CBD from hemp, defined as any variety of cannabis plant containing less than 0.3% THC by dry weight. Cannabinoids and terpenes are produced by tiny glands on the leaves and flowers of cannabis plants known as trichomes. The compounds produced by these trichomes give cannabis both its rich aroma and its nutraceutical effects.

CBD has positive implications in a vast number of illnesses and has been shown to boost general health, hair and skin.  Research isn’t conclusive here, although it is strong, and in the coming years, we are expecting to see more and more evidence.  THC, on the other hand, can benefit other disorders but comes with drawbacks, such as the feelings of being high and possible induction of feelings of anxiety and paranoia and more.
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.  

I am very impressed with this CBD oil. I tried other brands with lower dosage and was not really happy. This dosage seems to work great for me, I have a crunched vertebrae from a quad wreck, and the mornings have always been the worst. Within a day I was already noticing great relief. I have contacted Medterra a few times and each time they were quick to respond and very helpful. I will always do my CBD business with this company!

Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[24][25] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[26] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[27]
Several studies conducted between 2004 and 2008 demonstrated the variable effect of different cannabinoids on sleep. In one, 15 mg of THC appeared to have sedative properties, while 15 mg of CBD appeared to have alerting properties.[416] Another tested the effects of CBD on animal models in both lights-on and lights-off environments and found that this non-psychoactive cannabis compound increased alertness with the lights on and had no discernable effects on lights-off sleep. The study’s authors concluded that CBD might actually hold therapeutic promise for those with somnolence, or excessive daytime sleepiness from a not-so-good night’s rest. Another study found CBD to be wake-inducing for most subjects, though some reported better sleep a few hours after taking it. [417]
What exactly is cannabidiol (CBD) and more importantly, what does it do? Those questions and more are at the heart of this comprehensive guide to one of the most fascinating and important compounds of the cannabis plant. Cannabis plants are chemical powerhouses that produce more than 400 different compounds. Not all of those compounds are unique to marijuana, of course, and appear in many other species of plants. That’s why marijuana can smell like pine trees or taste like fresh lemons. But of those 400 compounds, more than 60 of them are totally specific to the plant genus Cannabis. Scientists call these special compounds “cannabinoids.” However, not all cannabinoids are created equal. One of them, cannabidiol, or CBD, holds the key to the wide variety of medicinal and therapeutic effects marijuana offers.
Also important is terpenes’ ability to enhance the properties of CBD. This phenomenon, called the “entourage effect,” is considered by many experts in the industry to be essential for gaining the full benefit of the plant. It also points to the importance of using a full-spectrum extract of hemp, which provides a full range of chemical components including terpenes, as opposed to purified CBD or CBD isolate, which contains only CBD.

CBD, often ingested in oils, tinctures, and the occasional gummy bear, is really just a form of hemp- or marijuana-derived oil. It contains no psychoactive properties (so you don't feel high), but there are growing studies showing CBD's positive effects on anxiety, pain, and epilepsy in children. While CBD is totally legal, what are you supposed to do if you're asked to take a drug screening? Will CBD show up on a drug test? Can you get fired for using CBD? I spoke to some experts to get some clarification on how CBD oil could potentially affect your test scores.


There are thousands of unique varieties of hemp. The cultivars used for CBD oil contain significantly higher concentrations of CBD than others. Using these uniquely potent plants, it is possible to extract cannabis oil that contains significant levels of cannabidiol, as well as essential vitamins, minerals, fatty acids, terpenes, flavonoids, and other non-psychoactive cannabinoids.

Nature’s Script also sells a pet CBD tincture in 150mg, 300mg, and 1,000mg concentrations. As a general rule of thumb, low-concentration oils are a good option for smaller dogs while larger concentrations may be more suitable for larger breeds – but pet owners should always check with their vet beforehand. In addition to standard shipping, Nature’s Script offers expedited delivery for customers in the contiguous U.S.

A couple of studies dealt with drug and substance abuse. From them, we’ve learned that if you use CBD, you can decrease your drug-seeking behavior and be less dependent. CBD oil has a notable effect on the brain circuits responsible for addiction. Once it alters your circuitry, you’ll have less desire to depend on any substance. Can you use CBD to quit smoking and prevent other addictions?

Among all of the experts, there's no hard and fast rule on how long it stays in your system. Again, if you've had pure CBD, it shouldn't matter when you had it last since it won't show up in urine tests. If you've had CBD and THC, the Colorado Pot Guide suggests you'll be positive on a drug test within seven days of use. Now, if you take in a lot of THC, you could test positive for a month or more.
I did an analysis of 10 diffirent CBD oils and Medterras 3000mg bottle is the most cost effective per mg. Their product also appears the safest with where they source their materials and how they conduct their business. There were no issues with the ordering process and I received my product in a timely fashion as well. There is almost no taste to the oil and I take 25 ml (25 mg) twice daily with excellent results. I finely feel calm and sleep well. I am also able to focus better and get more done each day, which was an unexpected bonus. I was very sceptical about CBD at first. I have tried everything for my anxiety, and although some of the traditional drugs work, their side effects negate any benefits. I was feeling very frustrated and hopeless and ordered the CBD out of desperation. Im glad I took the chance. Well, it wasnt really a chance; I read every research article I could get my hands on and was swayed by the emerging data. I guess it was more of a leap of faith in a product that had such high claims and no healthcare gatekeepers. I have had no side effects though. The only negative is the cost.
CBD oil contains CBD (and often other active compounds) in a carrier oil. There are a number of forms of CBD oil, including softgel capsules, tinctures, and under-the-tongue sprays. Some forms of CBD oil can also be applied directly to the skin, in the form of products like creams and salves. The concentration of CBD varies from product to product.

A wealth of marketing material, blogs and anecdotes claim that cannabis oils can cure whatever ails you, even cancer. But the limited research doesn't suggest that cannabis oil should take the place of conventional medication, except for in two very rare forms of epilepsy (and even then, it's recommended only as a last-resort treatment). And, experts caution that because cannabis oil and other cannabis-based products are not regulated or tested for safety by the government or any third-party agency, it's difficult for consumers to know exactly what they're getting.


To calculate the cost per milligram of CBD, simply divide the dollar amount of the product by the total milligrams of CBD in the bottle. So for instance, a product with 600 mg CBD in a 1 fluid-ounce bottle costing $80 is equal to about 13 cents per mg of CBD; a product with 100 mg of CBD in the same size bottle selling for $40 works out to 40 cents per mg of CBD. In this case, it pays to splurge on the $80 bottle.

CBD products with a ratio of 20:1 or higher are recommended and administered as drops, capsules, or edibles. Specifically, products made with Valentine X or Electra 4 are more energizing, helping relieve depression. When low energy is an issue, sativa or other stimulating strains can be helpful for improving energy and focus when THC can be tolerated. Varieties that are high in the terpene limonene are recommended for mood elevation.
Dispensaries: In states where marijuana is legal for recreational use, dispensaries are a common sight. They are much rarer in states with more restrictions. In states that permit the use of medical marijuana, hemp-based CBD oils do not normally require a prescription but marijuana-based oils do. Like brick-and-mortar locations, dispensaries offer more customer service. However, as noted, this may not be an option depending on the buyer’s state of residence. Also, CBD oil prices tend to be significantly higher at dispensaries.
Here, the evidence is not going to make them happy. A 2017 study in JAMA reported that only 26 of 84 samples of CBD oils, tinctures and liquids purchased online contained the amount of CBD claimed on their labels. Eighteen of them contained THC, which could lead to intoxication or impairment in some individuals. And a quarter had less CBD than advertised. The F.D.A. has likewise found many products that did not contain the amount of CBD they were claiming.
