CBD Oil Market Research

Commissioned for Alphagreen website, this Product Trend Analysis inspects user searches surrounding the topic of CBD Oil and other CBD products, with the UK as the anchor market. However, we also checked other markets and worldwide data in order to spot significant differences or trends that may be relevant.

During the pandemic, the CBD product searches have changed and the demand has been increasing in the UK day by day. However, the US and the UK markets show some differences during this period.

Consumer interest in CBD has risen rapidly and is growing fast. At a glance, we can tell that this has affected search trends and online product demand in a positive way. In this analysis, you’ll observe how search trends have changed and how users are searching for CBD products.

Firstly, here below Top-10 keywords in the UK market:

*The search terms show similarity, but the search volume is higher in the US as expected.

However, search volumes are estimated and only show the average over the 12 months. In 2020, it is more important to track popularity, seasonality, and trends since we are living through a pandemic and user behaviours are changing and needs are evolving. Within this scope, we analyzed the trends of the most important keywords by using Google Trends in order to spot the demand before and after Covid-19 and high/low seasons if there are any.

Here is the 1-year trend data for the “CBD oil” keyword in the UK:

The first confirmed case of the coronavirus recorded in the UK was January 31st 2020. After the first recorded death from the virus on the 5th of March, social distancing measures were encouraged by the Prime Minister. This included avoiding social venues such as bars and restaurants, stopping all non-essential contact, and working from home if possible.

In the first few weeks of the pandemic, the search trend of “CBD Oil” declines, but then it starts getting popular again. The demand is still high and it seems like it will be increasing in the coming days.

However, the US data is different from the UK market. The downward trend in CBD oil is likely to continue:

Product Trends

Apart from CBD Oil, we also checked which type of products users are searching for and which ones are getting popular in the UK:

CBD Vape and CBD Gummies are highly popular products when compared to others like tea or chocolates.

However, when we searched for the 5-year trend, we saw that last year (2019) cbd vape was more popular than this year, but cbd gummy searches continue to grow:

In the US, gummies are more popular:


  • The demand has been increasing in the UK market unlike the US market, where there has been a decline.
  • CBD products seem to be getting more popular and the data showed us that there is no high or low season for these products, except during the pandemic period. Users are searching for them all year round.
  • Most popular products are CBD Vape and CBD Gummies.
  • Users are more likely to search with brand names.

Does CBD help with insomnia?

Supporting evidence: Shannon (2016) presented a case report suggesting that consuming CBD oil may be helpful for PTSD-associated anxiety and insomnia.

Opposing evidence: A study by Vigil et al. (2018) analysed the participant data regarding how their insomnia symptom changes upon consuming medical cannabis flower across a time period from June 2016 to May 2018. They eventually reported that medical cannabis flower consumption is linked to significant reduction in the severity of insomnia. However, this study used cannabis flowers as part of their investigation. Given that this flower contains a number of cannabinoids, it is hard to identify if CBD was the key contributor to this outcome.

Neutral opinion: Shannon et al. (2019) studied a clinical population of 103 adult patients to investigate if taking CBD can assist in improving sleep and/or reduce anxiety. They discovered that CBD may be beneficial to treat anxiety disorders, which may indirectly help with sleep disorders. Nonetheless, they explicitly mentioned that controlled clinical studies are mandatory before an official conclusion can be made. This statement was also supported by Harvard Medical School, who pointed out the lack of high-quality evidence in human studies to prove that CBD is medically effective option for insomnia.

Besides that, the committee of the National Academies of Sciences, Engineering, and Medicine concluded that there is a moderate amount of evidence showcasing that cannabinoids, namely nabiximols (which has THC and CBD as the primary active ingredients), could help patients with sleep disturbances. However, they specified that these are mainly for sleep disturbances caused by obstructive sleep apnea syndrome, fibromyalgia, chronic pain, and multiple sclerosis. In other words, they did not have any data on the effects of CBD on primary chronic insomnia.

Does CBD help with epilepsy?

Supporting evidence: There have been various research investigations implying that CBD may be an efficacious treatment option against epileptic seizures that are difficult to treat using conventional medications.

For example, a meta-analysis on 36 clinical trials by Stockings et al (2018) recorded an inverse relationship between the usage of CBD and the reduction in the frequency of seizure attacks amongst clinical trial patients. Besides that, another 2018 investigation by Pamplona et al. found that consuming CBD-rich extracts is typically more therapeutically effective than CBD isolates.

In terms of the health and safety aspects of CBD, the research findings by O'Connell et al. (2017) and Silvestro et al. (2019) supported the notion that the FDA-approved CBD-based epileptic medication, Epidiolex, is considered to be safe and effective in treatment-resistant epilepsy.

Neutral opinion: A preliminary study by the American Academy of Neurology suggested that artisanal CBD, which contains a mixture of CBD and THC, might not be an effective treatment for epilepsy compared to pharmaceutical CBD (which has zero THC content). Nonetheless, they acknowledged that this study did not involve a clinical trial - this means that no direct comparisons between the effectiveness of pharmaceutical and artisanal CBD were made. Henceforth, this speculation might be inaccurate.

Meanwhile, Gloss and Vickrey (2014) authored a systematic review specifying that no reliable conclusions can be made regarding the effectiveness of cannabinoids for epilepsy treatment. A similar conclusion was also made by the National Academies of Sciences, Engineering, and Medicine.

Is CBD good for fibromyalgia?

Opposing evidence: The pain-relieving effects of inhaled pharmaceutical-grade cannabis - which contains a mixture of tetrahydrocannabinol (THC) and cannabidiol (CBD) - was explored by Donk et al. (2019). They found that CBD may have antagonistic actions against THC’s analgesic effects, thus contributing to the counterproductivity of the medication.

Neutral opinion: Although Berger et al. (2020) reported that there are emerging data proposing that cannabis has a positive medical effect on fibromyalgia patients, they mentioned that there is insufficient data in general to pinpoint which particular cannabinoid is involved. Hence, this would require further research.

Is CBD good for itch relief?

Supporting evidence: The National Eczema Association (NEA) reported that CBD does possess anti-itch properties, which can be extremely helpful in eczema or psoriasis treatment.

How can CBD help with sexual well-being?

Neutral opinion: There has not been any clinical studies that directly proves the ability of CBD to help with sexual well-being. Nevertheless, CBD may indirectly boost a person’s sexual wellness due to its anti-inflammatory and analgesic properties, which may help in pain reduction caused by penetration during sex.

Meanwhile, Androvicova et al. (20017) suggested that cannabis can help to improve an individual’s sexual desire, but this does not necessarily mean that CBD is the key contributor. As highlighted by Shamloul et al. (2011), this area of research is still at its infancy stage and further research is required.

Is CBD good for migraines?

Supporting evidence: A case report by Hegazy et al. (2019) postulated that CBD is a promising treatment for headaches caused by chronic pain within a patient suffering from the neurofibromatosis type 1 (NF1) disorder.

Opposing evidence: Baron et al. (2018) reported that THC is the most likely contributor to the reduction of migraines instead of CBD, given that the majority of conventional cannabis strains used have a high THC content and low CBD content.

Neutral opinion: A study by Cuttler et al. (2020) reported that taking cannabis may reduce the effects of headache and migraine by approximately 50%. Nevertheless, they were not clear on the exact cannabinoid within the cannabis that contributed to this and also acknowledged that their results were obtained without a placebo (i.e. a control group) along with a possible sampling bias issue. Henceforth, further research is needed.

Can you take CBD to treat arthritis?

Supporting evidence: There is generally an underwhelming effort surrounding the potential use of CBD to treat arthritis. However, several experiments conducted on animals which proposed that CBD possesses anti-inflammatory and pain-relieving properties, which may be helpful for arthritis treatment. For instance, Russo (2008) studied the analgesics properties of CBD in rats, they found that CBD can inhibit tumor necrosis factor-alpha (TNF-α) - an inflammatory agent - within rat models of rheumatoid arthritis, and thereby reduce pain associated with inflammation. Other than that, Lowin et al. (2020) suggested that CBD has anti-arthritic properties that may help alleviate arthritis symptoms.

Neutral opinion: Harvard Medical School noted that well-established human clinical trials showcasing the safety and efficacy of CBD to treat chronic arthritis pain is non-existent. A randomized controlled trial by Hunter et al. suggested that CBD could be used to treat knee-associated osteoarthritis of the knee, but the study is only available as an abstract form (thus no direct evidence was presented). In addition, a review by Fitzcharles et al. (2016) was unable to draw any confident conclusions regarding using cannabinoids to treat rheumatoid arthritis due to previous studies having a small sample size and study duration. Richards et al. (2012) also suffered a similar fate.

Can CBD oil help you stay alert?

Neutral opinion: A review by Murillo-Rodríguez et al. (2014) concluded that CBD may indirectly act as an alertness-inducing agent through promoting a healthy sleep cycle.

Can CBD help psoriasis?

Supporting evidence: A 2007 study by Wilkinson et al. showcased that cannabinoids are capable of halting the proliferation of keratinocytes, thereby demonstrating its potential to treat psoriasis. In particular, they found that CBD is one of the compounds (besides CBG) that presented the highest overall activity amongst all the cannabinoids tested. Moreover, Palmieri et al. (2019) highlighted that applying CBD topically (in the absence of THC) is considered safe and effective to treat skin disorders, including psoriasis. A patent filed in 2019 for psoriasis treatment using a mixture of CBD and CBG showcased dose-dependent effectiveness in clinical trial participants.

Neutral opinion: A 2019 review by Sheriff et al. implicated that cannabinoids hold a potential ability to to treat a number of skin conditions. However, they did not specify whether CBD takes the full credit for this or not, given that there are more than 100 types of cannabinoids found in the Cannabis sativa plant. A similar finding was also reported by Scheau et al. (2020). However, they clearly indicated that further controlled human studies are necessary to pinpoint the main cannabinoid involved.

Can CBD oil help with sciatica?

Neutral opinion: There hasn’t been any scientific studies focusing on the potential of CBD to treat sciatica. Nevertheless, given that one of the key symptoms of sciatica is neuropathic pain, Jo et al. (2016) reported that a patient suffering from these symptoms experienced pain relief after consuming a cannabis strain that has 9% THC and 13% CBD. However, we cannot confidently say that CBD is the main component contributing to the pain relief, so further research is required.

How does CBD help with anxiety?

Supporting evidence: Shannon et al. (2019) is supportive of the notion that CBD may help with anxiety-associated disorders based on the findings of their investigations on 103 adult patients. Another study investigating patients having generalized social anxiety disorder (SAD) via functional neuroimaging proposed that CBD could lower the anxiety caused by SAD. This phenomenon was also reported by Bergamaschi et al. (2011), who had their study published in Nature.

Opposing evidence: Kedzior et al. (2014) indicated that there is a positive relationship between the consumption of cannabis and the increment in anxiety levels, though they did not specify if CBD was the key contributor or not.

Neutral opinion: Although Blessing et al. (2015) is in favour that CBD possesses anti-anxiety properties, they emphasised that human studies focusing on the chronic CBD dosing are extremely limited, so additional studies will be required. Meanwhile, Blanco et al. (2016) asserted that there is no solid connection between the use of cannabis and the prevalence of anxiety disorders.

How does CBD help with depression?

Supporting evidence: A 2018 study by Sales et al. indicated that CBD has a promising therapeutic profile as an antidepressant when it is given to rats. This phenomenon was also reported by Shoval et al. (2016) in their rat model of depression too. Meanwhile, Crippa et al. (2018) noted that the antidepressant-like effects of CBD contributes to the lowering of stress in human subjects. Still, it is important to note that most of the previous investigations on the antidepressant effects of CBD were conducted on animals, so more human studies would be needed.

Opposing evidence: A study by Crane et al. (2015) and Gage et al. (2015) reported that cannabis used is associated with the increased risk of developing depression symptoms.

Does CBD help with glaucoma?

Opposing evidence: The American Academy of Ophthalmology specifically pointed out that taking CBD may worsen the symptoms of glaucoma due to its ability to increase eye pressure, which is detrimental for such conditions. Furthermore, Miller et al. (2018) reported that CBD can increase the eye pressure amongst rats by 18% when they received eye drops.

Neutral opinion: A review by Whiting et al. (2015) referred to a clinical trial that presented no difference, in terms of the effects, between placebo and cannabinoids regarding the intraocular pressure amongst glaucoma patients. The National Academies of Sciences, Engineering, and Medicine was also unable to identify specific studies proving the beneficial or harmful effects of CBD to treat glaucoma.

Does CBD help with dementia?

Neutral opinion: van den Elsen et al. (2014) highlighted that more adverse side effects were reported in patients receiving cannabinoid treatment, though the weakness of the studies they analysed is the extremely small sample size. Thus, no solid conclusion can be made yet. In general, the Alzheimer’s Society clearly stated that there is no scientific evidence proving that CBD can prevent, reverse or stop dementia.

Can CBD help with Parkinson’s disease?

Neutral opinion: Chagas et al. (2014) revealed that CBD might be able to improve the quality of life of Parkinson’s patients, but larger scale clinical trials with better defined research objectives would be a necessity to offer concrete evidence. A similar conclusion was also made by Lotan et al. (2014) too.

Can CBD help with Tourette’s syndrome?

Neutral opinion: The National Academies of Sciences, Engineering, and Medicine reported no clear association between the use of CBD and its effects on Tourette’s syndrome.

Can CBD help with cancer?

Supporting evidence: Velasco et al. (2016) mentioned that CBD can prevent metastasis in several animal models, thereby expressing notable anti-cancer properties. The National Cancer Institute has also noted several studies, such as Caffarel et al. (2010) and McAllister et al. (2010), that argued for the positive effects of CBD in cancer treatment. A mouse model by Aviello et al. (2012) have also demonstrated the chemopreventive effect of CBD.

Can CBD help with chemotherapy-induced nausea and vomiting?

Neutral opinion: The American Cancer Society implied that marijuana might be useful to help treat nausea and vomiting that is caused by cancer chemotherapy.

Can CBD help with irritable bowel syndrome?

Neutral opinion: Hoffenberg (2018) mentioned a possibility of using cannabis to treat irritable bowel syndrome, but more research is needed.

Can CBD help with Huntington’s Disease?

Neutral opinion: Consroe et al. (1991) concluded that CBD possesses neither beneficial nor toxic properties to treat Huntington’s Disease. The National Academies of Sciences, Engineering, and Medicine also made the same conclusion.

Can CBD help with post-traumatic stress disorder?

Supporting evidence: Elms et al. (2019) highlighted that taking CBD orally along with attending routine psychiatric care is linked to reductions in PTSD symptoms. In addition, Bitencourt et al. (2018) implicated that several studies on rodents presented promising applications of CBD to relieve PTSD symptoms. Campos et al. (2012) reported a similar outcome too.

Neutral opinion: Lake et al. (2019) pointed out that cannabis/cannabinoids may hold the potential to treat PTSD, though they didn’t specify if CBD was the key factor involved.

Can CBD help with treating strokes?

Supporting evidence: An ischemic stroke model by Khaksar et al. (2017) indicated that CBD might have neuroprotective properties that can protect one from ischemic damages.

Neutral opinion: Hayakawa et al. (2010) stated that CBD may have therapeutic potential to treat ischemic stroke, though further study is required.

Can CBD help with asthma?

Supporting evidence: Vuolo et al. (2015) reported that the anti-inflammatory properties of CBD is a helpful contributor to alleviate asthma symptoms.

Can CBD help with chronic obstructive pulmonary disease?

Supporting evidence: Ribeiro et al. (2014) proposed that CBD holds therapeutic potential to treat COPD in future, but additional investigations is necessary.

Opposing evidence: Makwana et al. (2015) argued against this notion as they found that it is mainly THC that demonstrated medical effects to treat COPD symptoms.

Neutral opinion: Mamber et al. postulated that cannabis oil could affect the gene expression of certain airway epithelial cells, though they did not specific if that was due to CBD.
