Research on low levels of CBD is, you guessed it, incredibly limited; just a single paper on the medical research database PubMed specifically looked at CBD in these low doses, as a treatment for Crohn’s disease. (It was not found to have an effect.) As such, it wouldn’t be fair to say that 5 or even 20 mg of CBD oil in your coffee is proven to do nothing; that hasn’t been proven. It’s more accurate to say that 20 mg of CBD oil in your coffee has never been proven to do much of anything, and related research indicates that’s probably way too low of a dose to have any measurable effect.
“The standard dosage, I would say, is around 20 mg per serving,” says Joshua Tavares, the general manager of Clover Grocery, which sells a wide variety of CBD products including gummies, tinctures, and topical lotions. (Tavares describes the shop, which also sells artisanal potato chips, as a “bougie bodega.”) “The main benefits that we touch upon when selling the products are that CBD is helpful for anxiety and providing you with a sense of calm. I would say it’s our top seller since we brought it in. The CBD category in general is really booming right now for us.”
Oil has become a favorite mode of administration for many medical users of cannabis and cannabinoids for multiple reasons. First of all, concentrated extracts allow the consumption of a large dose of cannabinoids in an easily ingestible form. With CBD oil, there is no risk of intoxication (getting high) , so much larger doses can be consumed than would be possible for THC-rich products. Many users who prefer the holistic approach of using herbal cannabis worry about the stigma associated with the typical smell caused by smoking or vaporizing it. Cannabis oil has no smell that may identify a consumer as a cannabis user, and it can be used discretely even in a social setting, e.g., at work or around family. Moreover, it can be efficiently dosed simply by counting the number of drops consumed. These same benefits of using a concentrated extract were identified in a large survey among medicinal cannabis users published in 2013 , perhaps as an early indicator of the emergence of cannabis oils as a preferred method of ingestion. Currently, the market is developing further towards more sophisticated and patentable products, including oral capsules, liposomal products, skin creams, and chewing gums containing CBD.
Some individuals have been found to have mutations on the CNR1 gene, which is responsible for coding the CB1 receptor (a type of receptor in cells throughout your body that interacts with cannabinoids). Issues with the CNR1 gene can ultimately result in a poorly functioning endocannabinoid system, which is an important variable when figuring out how to use CBD oil.
Cannabidiol is currently a class B1 controlled drug in New Zealand under the Misuse of Drugs Act. It is also a prescription medicine under the Medicines Act. In 2017 the rules were changed so that anyone wanting to use it could go to the Health Ministry for approval. Prior to this, the only way to obtain a prescription was to seek the personal approval of the Minister of Health.
