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.
Biopurus features a large range of concentrates, from the 5% CBD whole-plant extract to the strongest 30% CBD oil. The only caveat with this whole-plant extract (which is beyond full spectrum) is that it has a stronger, thicker texture than a regular CBD oil, and needs to be stored in an upright position to avoid any leakage. A Biopurus extract is not suitable for travelling or bringing along to the commute, but if you’re happy to keep it in your cupboard and have it before breakfast and dinner, in our opinion, this is by far the best range of organic CBD oils you can get.
CBD hemp oil has a number of uses and comes in many forms including capsules, tinctures, sublingual supplements, liquid oil, oil as a paste, sprays, salves, creams and in edible forms, such as candies or sweets. You can also inhale CBD oil from vapor-releasing pens, similar to the technology for e-cigarettes. This variety also provides a lot of controlled flexibility in terms of concentration, making CBD hemp oil useful and desirable for people of all ages, economic means, and personal needs.
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.
Recently I have experimented with vaped THC marijuana flowers which gives me about 5 hours of better-than-Tramadol pain relief from a single puff.  The accompanying high is very mild, like an ounce or two of wine.  This may be working for me due to the THC reaching my blood stream directly without having to go through my liver.  In any case, the pain relief from vaping greatly exceeds the pain relief from taking essentially the same dose orally, even though the oral dose is more intoxicating.  I’m not sure I will be able to completely stop using Tramadol this way, but this seems to offer a hopeful path.  FWIW correctly dosing vaped cannabis is very tricky, best to get some coaching from an experienced vaper otherwise you will initially grossly overdose which will not kill you but may not be to your liking.  I have also tried vaping CBD-only hemp flowers with essentially no results, would be interested to hear from others about their experiences with that…
A study published by David Cheng, Postdoctoral Scientist, Neuroscience Research, University of New South Wales, NSW, Australia, says that CBD has a potential as a preventive measure against symptoms of Alzheimer’s. This presents yet another exciting development for medical researchers, given the persistent challenges to finding effective solutions for this condition.

So, what is the best way to use CBD oil? CBD comes in a variety of forms, such as oil, tincture, oil for vaping, sublingual spray, edibles, and topical creams, so you can choose the method that is most suitable for your use. The main idea behind all the methods of using CBD is to make sure that this cannabinoid ends up in your system in an easy manner, producing the results you want. But when it comes to choosing the right method, it depends very much on the optimal dose in your case, the results you wish to achieve, and how long you want its effects to last. So, there isn’t a general rule when it comes to using CBD products.
