Created by the larger-than-life grower and activist Lawrence Ringo, Sour Tsunami was brought into being by combining Sour Diesel and NYC Diesel. This unlikely pair of stimulating plants bred the high-CBD phenotype that has since redefined the medicinal qualities of cannabis.

Cannabidiol, or CBD, is the second most common cannabinoid found in cannabis. Unlike its euphoric sister, THC (or tetrahydrocannabinol), CBD plays it cool, offering relaxing, non-intoxicating effects that lend themselves to a variety of personal and medicinal uses. Because CBD lacks the stoney side effects typical of high-THC strains, it’s a great choice for patients needing to keep a clear head while treating pain, nausea, headaches, stress, anxiety, muscle spasms, epilepsy, and more.

Just as you can search for strains high in THC, sativa, or indica, you can also search for strains high in CBD – and Leafly users do just that.

If you’re interested in finding high CBD strains yourself, look for strains that contain only circles in their Leafly strain flower. This will help you find strains that consistently express high levels of CBD, which is more likely to bring you clear-headed relief. But if you’re ready to cut to the chase, here are the top picks from our users:

Canna-Tsu is a more balanced CBD/THC strain that offers a unique bouquet of smells. With aromas of citrus and sweet earth, Canna-Tsu gives the CBD enthusiast a complex palate of flavor and terpenes to enjoy.

CBD stands for cannabidiol, a non-intoxicating cannabis molecule with a variety of anecdotal and studied benefits. Strains high in CBD are popular with users for help with:

Harle-Tsu, one of a few lovingly handcrafted strains created by the late Lawrence Ringo, is an outstandingly functional CBD cut. By combining Harlequin and Sour Tsunami, Harle-Tsu achieves a pleasant disposition without encumbering the consumer with strong sedation.

What does it mean for a strain to be high in CBD?

Stephen Hawking Kush offers mild, relaxing effects while doling out a healthy dose of CBD, too. This indica-dominant strain is one of the more unique CBD cuts out there, offering both heady and soothing effects.

ACDC makes an easy favorite.The cannabinoid content is usually heavily CBD-dominant, sitting on average at 20:1 in its CBD/THC ratio. An imperceptible amount of THC makes ACDC an outstanding companion for daily medicinal cannabis consumers seeking to relieve tension, pain, or anxiety.

If you think about it, there are commonsense reasons why these limits exist. When appropriately labeled, cannabis products tell you how much THC, CBD, or other compounds are present as a percentage of the dry weight of that product. If the flower you buy is labelled as having 25% THC by dry weight, it means that 25% of the mass of the flower, after it has been dried to remove water, comes from THC. That means 75% of its dry weight comes from other things: fats, carbs, proteins, vitamins, and minerals. All that stuff. More THC or CBD means less of those things, which the plant depends on for survival.

F or decades, growers have used selective breeding to create strains with ever-higher levels of THC. Some have done the same to produce low-THC, high-CBD profiles. But is there a limit on the THC or CBD levels that cannabis can produce? Or will growers continue to pack more power per pound into the plant?

The above graphic is based on real data—over 1,200 laboratory measurements from commercial strains in the state of Washington. Almost all strains fall into one of the three shaded regions above. And this isn’t anything new—botanists have known about this general pattern for years, and have used the THC:CBD ratio to classify landrace strains into three “chemotypes.”

Figure 1: THC and CBD levels generally fall within three broad ranges. Almost every strain will fall into one of these. 30% total THC by dry weight should be considered very potent, and it’s difficult to get plants to produce much more than that. Balanced strains will have both CBD and THC, but at intermediate levels. The very center of each trio of rings is the average THC and CBD content for that strain category. Each shade of purple represents one standard deviation. The majority of strains in each category will fall within the innermost, dark purple ring. Note: the THC-dominant rings have been stretched vertically for visualization purposes. (Photo credit: Amy Phung/Leafly)

Lab Data Shows Limits on THC and CBD Levels

Most balanced strains will tend to have CBD and THC levels in the neighborhood of

Because CBD and THC are ultimately derived from CBGA, and strain genetics limit how that happens, there are serious biological constraints on the THC:CBD ratios that strains can have. You can see this clearly by looking at a plot of THC vs. CBD content across many strains, which will look something like what you see in Figure 1.

6-12%. But you should never see a strain with 30% THC and 10% CBD, or one with 30% of both. The biology of THC and CBD production prevents this. Be skeptical if you see flower claiming to contain anything very far from the shaded purple regions in Figure 1.

Peak THC: The Limits on THC and CBD Levels for Cannabis Strains

35% total THC by dry weight is a rough upper limit for strains. On average, high-THC strains contain

18-20% total THC, while the more potent strains will contain
