Key takeaways:
- CBD-rich cannabis is growing in popularity. Scientists classify these as either Type II (High THC/ High CBD) or Type III (High CBD/Low THC) cannabis varieties. Hemp flower is the most popular type of CBD-rich cannabis.
- CBD-rich cannabis may reduce cannabis intoxication and other side effects, such as anxiety and short-term memory impairment. It’s also more suitable for relieving stress and anxiety and can help with addiction to a variety of substances, including THC.
- CBD possesses antioxidant, anti-inflammatory, and autophagy-inducing properties that may extend lifespan and healthspan, but further research is needed.
A majority of cannabis strains in the medical and recreational markets today are higher in THC than in CBD. But cannabis high in CBD, like hemp flower, is becoming increasingly popular as people learn more about the benefits of CBD and seek less-intoxicating experiences.
These are what scientists would call Type II (High THC/ High CBD) and Type III (High CBD/Low THC) cannabis varieties, in contrast to the more prevalent Type I (High THC/Low CBD) strains (1).
In this article, we’ll discuss the top benefits of using such CBD-rich cannabis strains, including fewer psychoactive effects, reduced anxiety and stress, and helping with drug addiction.

May Reduce Intoxication and Side Effects
The main benefit of opting for CBD-rich cannabis strains is that they have fewer psychoactive effects. This makes them a great option for beginners, people looking for medical benefits without the intense high, and those who want to stay productive while using cannabis.
These groups are best suited by cannabis strains with CBD to THC ratios ranging from an even 1:1 to as high as 20:1.
Another important benefit is that as the CBD ratio in cannabis goes up, the likelihood of side effects like anxiety, short-term memory impairment, and psychosis goes down.
For example, one 2018 study examined the effects of CBD on acute memory in 134 people smoking cannabis with varying levels of CBD, finding that those “smoking cannabis high in cannabidiol showed no memory impairment” and that “use of strains richer in cannabidiol may protect cannabis users from the chronic psychotic-like effects of THC (2).”
Another 2011 study surveyed 1877 people about their cannabis use, finding that “although the observed effects are subtle, using high cannabidiol content cannabis was associated with significantly lower degrees of psychotic symptoms (3).”
Meanwhile, an innovative 2012 study correlated the levels of CBD and THC in the hair of 120 cannabis users to psychosis, memory issues, anxiety, and depression.
Those who had CBD in their hair had lower psychosis-like symptoms and better recognition memory than those who didn’t. Higher hair THC levels were also associated with worse depression and anxiety (4).
But there have also been negative findings. One 2019 study found that vaping cannabis with a 1:1 THC and CBD ratio was no less impairing than using THC-rich cannabis, and actually increased cognitive impairment during simulated driving and cognitive performance tests (5).
Conflicting research like this strengthens the argument that more research is needed to confirm if and how CBD may or may not affect THC.
May Be Ideal for Anxiety and Stress
CBD-rich cannabis may also be better suited for helping with anxiety and stress. For starters, research has shown that CBD has potent anxiolytic (anxiety-reducing) properties, so it’s reasonable to say that cannabis with more CBD is better for lowering anxiety:
- In a 2019 study of teenagers with social anxiety disorder, CBD oil lowered anxiety (6)
- In a 2022 study of people with treatment-resistant anxiety, CBD improved both anxiety and depression symptoms (7)
- A 2020 review of numerous studies concluded that “CBD has a promising role as alternative therapy in the management of anxiety disorders” (8)
Meanwhile, in a 2018 study, people reported that high THC/high CBD cannabis (defined as strains with more than 11% CBD and 26.5% THC) was the best at improving symptoms of stress (9).
In another 2021 study, people using CBD-dominant and 1:1 strains reported less paranoia and anxiety compared to those using THC-rich strains (10).
At the same time, the researchers noted that the presence of CBD was not necessarily the reason for reduced anxiety, but rather less THC: “Cannabis chemovars containing CBD may result in less overall exposure to THC and subsequently less potential for harm.”
This idea gets further evidence from a 2022 clinical trial that tested whether CBD can protect against the side effects of THC.
Forty-six participants vaped cannabis containing four different CBD: THC ratios (10 mg THC, 0-30 mg CBD). The researchers reported that “At CBD: THC ratios most common in medicinal and recreational cannabis products, we found no evidence that CBD protects against the acute adverse effects of cannabis (11).”
But the study did have some limitations, like a small sample size and relatively low doses of CBD, so the scientists emphasized the need for more research.
May Help with Addiction
There’s also growing evidence that CBD could help with addiction to nicotine, opioids, cannabis, cocaine, amphetamines, and even alcohol, which means CBD-rich cannabis may help people with substance use disorders (12).
One 2021 review paper concluded that “CBD alone or in combination with commonly employed treatment strategies in drug addiction may configure a potential therapeutic option for improving the dishabituation process of addicted patients (12).”
Here’s a quick look at the key human findings:
- A 2010 study of 94 cannabis users found that smoking high-CBD strains reduced attentional bias (tendency to focus on something while ignoring other things) towards cannabis and food, suggesting that “CBD has potential as a treatment for cannabis dependence” (13)
- A 2022 study found that vaping CBD helped cannabis users reduce their daily cannabis consumption (14)
- A 2013 study found that smokers who used a CBD inhaler reduced their cigarette consumption by 40%, while another 2018 study reported that a single dose of CBD caused smokers to rate cigarettes as less pleasant (15, 16)
- A 2019 clinical trial found that CBD reduced craving and anxiety caused by drug cues in people with heroin use disorder (17)
Researchers believe CBD’s anti-addictive properties are related to its effects on the brain’s dopamine, opioid, serotonin, glutamine, endocannabinoid systems, and neurogenesis (the growth of new neurons in the adult brain) (12).
My Experience With CBD-Dominant Cannabis
I am a registered industrial hemp cultivator in Missouri, where I harvested hemp flower crops in 2021 and 2022 for research and personal consumption. As a marathon runner, I do enjoy consuming high-THC cannabis, but I also smoke my own hemp flower.
Cinderella Story is one of my favorite hemp flower strains our farm has grown. I personally don’t experience any psychoactive effects when smoking high CBD flower, but instead, I get a nice relaxed and calm feeling.
Choosing High-CBD Cannabis
To sum up, CBD-rich cannabis offers several key benefits, including less of a high and fewer side effects, lowering anxiety and stress, and helping with substance use disorders.
Still, many conflicting research results make it difficult to determine how CBD will affect each person, so experimentation is necessary.
If you’re interested in giving CBD-rich strains a try, popular options include Harlequin, ACDC, and Sour Tsunami. For those seeking an even milder alternative, hemp flower is an excellent option since it contains very low THC levels (less than 0.3%).
