Cannabidiol can be taken into the body in multiple different ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as an oil containing only CBD as the active ingredient (no added THC or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution.[1][3]

High-CBD strains can be smoked or vaporized for immediate effects with little to no high, depending on the strain’s THC content. A strain may contain only trace amounts of THC for clear-headed relief, or it may have balanced levels of THC and CBD, delivering a mild high but potent relief. Explore the menu of your nearby dispensary for a full list of the offerings near you, or browse high-CBD strains on Leafly for an idea of popular varieties to look out for.


A quality CBD topical cream provides the advantage of being able to apply the active therapeutic hemp extract directly to the site of aggravation or discomfort. This is particularly useful for application to joint areas or superficial muscle tissue, as the cannabidiol compound will diffuse across the dermal layers directly to the site of pain and inflammation.
As CBD oil is non-psychoactive, applying it to the skin does not create mind-altering effects in the same manner that THC ingestion does.3 Therefore, the use of CBD in topical form is a useful alternative for those who wish to avoid the psychoactive effects of THC and those who would like options besides the over-the-counter steroid-based creams typically used for arthritis, joint pain, and similar ailments. This is especially true for aging users, parents, or adults who are concerned about practical matters (like failing drug tests, for example).
There are a few ways to get CBD into your body. The most common, used in both clinical trials and consumer products, is via an oil in which CBD, which is naturally soluble in fat, has been dissolved. CBD oil can be taken orally, inhaled as a vape, or applied topically. Topical application is supposed to work sort of the way Icy Hot does, affecting a local muscle area specifically to reduce aches and pains, but the other methods produce full-brain and -body effects.
As mentioned above, cannabis and hemp differ in the levels of naturally occurring THC that they contain.  THC is a cannabinoid like CBD.  However, its properties are very different and often antagonistic to the effects of CBD.  Hemp is naturally high in CBD and low in THC; the reverse is true of cannabis.  In fact, hemp contains only about 0.3% – 1.5% THC, while cannabis contains about 5% – 10% or more THC.

Inhibited liver function: The liver regulates the way different drugs are metabolized within the body; this process is known as hepatic drug metabolism. Higher-than-average doses of CBD oil can slow the hepatic drug metabolism process. As a result, users may not be able to process other drugs as quickly. This is particularly concerning for CBD oil users who also take prescription medications.

Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[44] In strongly basic media and the presence of air, it is oxidized to a quinone.[45] Under acidic conditions it cyclizes to THC,[46] which also occurs during pyrolysis (smoking).[47] The synthesis of cannabidiol has been accomplished by several research groups.[48][49][50]


Almost overnight, CBD oils have become an interesting combination of popular holistic medicine, miracle cure, and a natural answer to the synthetic drugs dominating modern medicine. With CBD, patients receive the promise of being in control of their own ailments, and no longer feeling at the mercy of their treating physicians. This has turned out to be a particularly powerful message. Many patients use CBD oils freely for ailments both confirmed and self-diagnosed, and the rapid innovations with CBD products have actually been quite impressive. But while new CBD products keep entering the market virtually unchecked, effective regulatory control of these products has stayed far behind. As a result, unknown risks about long-term effects remain unaddressed, especially in vulnerable groups such as children, the elderly, and the chronically or terminally ill. It should be noted that this discussion goes well beyond CBD only, as new products containing additional cannabinoids like CBG, THCV, and acidic cannabinoids are following closely behind. We know even less about these compounds than about CBD, and very limited human safety data are available.
It’s crazy that CA would legalize recreational use of marijuana but ban CBD Oil. It’s does seem to be more motivated for financial reasons. Maybe they want more people to smoke and purchase marijuana because they can tax the hell out of it. CBD Oil is pricey but maybe the State of CA can’t figure out how to tax CBD Oil. This is like the government banning hemp based products after prohibition ended.
Tinctures are liquid cannabis extractions that are applied under the tongue. Soaked in either alcohol or vegetable glycerin, cannabis tinctures were among the earliest forms of cannabis medicines prior to its prohibition in the United States. They tend to be less concentrated than other oil extracts, but their effects kick in faster than ingestible oils and edibles.
The fact that the maximum CBD content in an oil is limited by the THC present in the herbal material used makes it attractive to add an additional amount of purified CBD to boost the percentage advertised on the label. Unfortunately, the Novel Food Catalogue of the EU states that “extracts of Cannabis sativa L. in which CBD levels are higher than the CBD levels in the plant source are novel in food” [35]. This means that enriching a natural hemp extract with pure (often synthetic) CBD makes it a Novel Food product, with the consequence that it must undergo significant safety assessment prior to being marketed. However, it is still unclear in many EU countries if extracts with no added CBD also fall under this regime.
Two cannabis-based pharmaceutical drugs, manufactured in the UK, are licensed for prescription but only for very specific uses. Sativex has been available in the UK since 2010 and uses THC and CBD to treat spasticity in multiple sclerosis. And a new CBD-only drug, Epidiolex, was approved in June in the US to treat rare childhood epilepsies, with a similar decision expected imminently for Europe and the UK.
