The 10 best CBD cannabis strains according to Leafly users

October 13, 2016
CasarsaGuru
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.

But with so many high-CBD strains hitting the market today, it can be difficult to choose one. These high-CBD strains are the most popular and easy-to-find based on Leafly user-submitted reviews.

1. Harlequin

Harlequin is one of the most popular CBD strains available. Typically testing around the 5:2 CBD/THC ratio, it exhibits a clear-headed alertness with only mild euphoria. Harlequin has a happy bent that most will find enhances whatever activity they are engaged in.

2. Ringo’s Gift

Ringo’s Gift—named for activist, CBD specialist, and founder of SoHum Seeds, Lawrence Ringo—is a hybrid cross of Harle-Tsu and ACDC. It keeps on giving to patients seeking a nearly full-on CBD-driven strain, with an average ratio of 24:1 CBD/THC.

3. Sweet and Sour Widow

Sweet and Sour Widow lands in the middle ground with a 1:1 CBD/THC ratio. This even split offers first-time cannabis consumers an enjoyable entry point to both THC and CBD without sending them into orbit. It also makes for good medicine while being slightly euphoric and stoney.

4. Stephen Hawking Kush

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.

5. ACDC

ACDC is easily my favorite CBD strain. 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.

6. Cannatonic

Cannatonic cannabis strain

Cannatonic isn’t nearly as sedative as the name implies. This strain usually brings a smaller CBD/THC split, ranging from 5:1 down to 1:1. This even-keeled cannabinoid profile gives consumers a great deal of flexibility to use Cannatonic as medicine or as an enjoyable, mild mannered strain to unwind with.

7. Harle-Tsu

Harle-Tsu cannabis strain

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.

8. Canna-Tsu


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.

9. Sour Tsunami

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.

10. Pennywise

Pennywise certainly has the scariest of all the names that made this list, or at least it does for those familiar with the Stephen King book responsible for its namesake. But fear not, Pennywise truly gets its name from its genetic cross of Harlequin and Jack the Ripper. It synthesizes Jack the Ripper’s mental clarity and an even 1:1 CBD/THC to make a strain that is functional and enjoyable at almost any dose.
