You can use pure CBD oil sublingually, or place it under the tongue. The capillaries in the mucous membranes absorb the CBD, and then they enter the bloodstream. What’s left of the oil is swallowed and digested. This method allows for immediate and long-lasting relief. If you choose to use CBD oil like this, make sure you’re holding it under the tongue for more than a minute so that it can be absorbed in the bloodstream. The active substances in the CBD interact with the endocannabinoid system within minutes.
Deciding to use CBD oil as a natural therapy is one thing – figuring out which brand to use, what strength/concentration to use, and how much CBD to actually take is another thing altogether. Plus, with all of the products out there to choose from and their confusing mL/mg labels, it can be a nightmare trying to determine which one is best for you, or which one you should be taking for your specific condition.
In your internet travels, you may also come across products called “terpsolates.” The manufacturers of these products infuse CBD Isolate with terpenes (but not cannabinoids like THC). These terpenes may enhance the effectiveness of CBD — or maybe they just make it smell good. This may be a good place to point out that not all CBD products are created equal. The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Third-party testing definitely helps to monitor companies’ claims, but it’s still up to you as the consumer to do your homework on the best CBD products.
“Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
The anxiolytic effect of THC is well documented, with other cannabinoids (especially CBD) also providing relief (if less potent). The exact pathways of the process have not been identified. A preliminary study published in 2013 in the International Neuropsychopharmacology Journal has set the foundations for further research linking CBD to future treatments for depression and psychosis.[25]
‘The media has no doubt helped drive this popularity,’ says Dr Sarah Brewer, medical director at Healthspan. ‘However, the main drive is because people who take it experience the benefits very quickly, and “word of mouth” is a powerful thing. CBD oil also has such a wide range of benefits, reducing anxiety, promoting relaxation, ensuring a good night’s sleep, reducing pain perception and improving general feelings of wellbeing. It therefore appeals to a wide range of people.’

Studies have demonstrated that CBD has a low affinity for the CB1 receptors, but even at low concentrations, CBD decreases G-protein activity (3). CB1 receptors are expressed on many glutamatergic synapses that have been implicated in seizure threshold modulation. CBD may act at CB1 receptors to inhibit glutamate release (4). Studies have shown changes in the expression of CB1 receptors during epileptogenesis and after recurrent seizures (5). CB1 receptor expression is upregulated at GABAergic synapses and shown to be downregulated at glutamatergic synapses in epilepsy, contributing to lowering seizure thresholds.
Sub-lingual CBD drops have helped me enormously with sleeping and with radiation damage pain. I have a cancer that spread from the pelvic area to my sacrum and sciatic nerve and whilst the chemo and radiotherapy saved my life I have been taking MST (morphine derivative) for nerve pain ever since. My tumours are presently all quiet and last March I decided I wanted to stop taking the pain relief drugs, fearing dementia. CBD oil was recommended by my son who has arthritis and, for me, it really works. It’s so good to read an article that isn’t put out by a CBD sales site – I wish it could be properly prescribed and regulated (I’m in the UK) in order to have confidence with purity and dosage.
CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.

Gloss and Vickrey conducted a Cochrane systematic review of the use of CBD in the treatment of epilepsy (11). Their methodology included only those trials that were randomized and controlled and excluded case series, case reports, and expert opinion. They were able to identify only 4 randomized controlled studies reported in the literature, and they included a letter to the editor and an abstract. The total number of subjects enrolled in these studies was 48 (11–14). While only four studies and a letter to the editor were in the actual analysis, the authors included a complete reference listing of all articles reviewed for inclusion.


As is the case with any plant that constitutes a crop, cannabis plants have been selectively bred over the years to bolster one or another desired characteristic. This means that some plants provide a more potent psychotropic effect, others possess more prominent seeds (used in the production of cooking oil traditionally), while others may make for sturdier textile fibers.
