10 Best CBD Heavy Strains

CBD (cannabidiol) is a non-psychoactive cannabinoid – meaning it won’t get you high. Instead, it works with your body’s endocannabinoid system to potentially reduce pain, ease inflammation, calm anxiety, and improve sleep quality. Unlike THC, which binds directly to brain receptors and produces euphoria, CBD takes a more indirect approach that keeps your head clear while your body relaxes.

The best high-CBD strains pair generous CBD content with minimal THC, creating functional relief you can use any time of day. We’ve blended timeless classics with some modern favorites to build this list. Here are the 10 best CBD-heavy strains worth trying.

Not all high-CBD strains hit the same. A few things to keep in mind:

CBD:THC ratio matters more than CBD percentage alone. A strain with 15% CBD and 1% THC will feel very different from one with 15% CBD and 10% THC. Ratios above 10:1 produce virtually no psychoactive effects. Ratios around 1:1 to 5:1 will have some mild, noticeable THC influence alongside the CBD.

Terpenes shape the experience. The aromatic compounds in each strain influence how it makes you feel. Myrcene promotes relaxation, pinene supports alertness, and caryophyllene may ease inflammation. Checking terpene profiles on lab results helps you predict whether a strain will calm you down or pick you up.

Hemp flower vs. cannabis flower. Many of the strains below are available as hemp flower (under 0.3% THC), which you can buy online in most U.S. states. Higher-THC versions require a dispensary purchase in a legal market.

• Type: Sativa-dominant hybrid
• CBD Content: 15-20%
• THC Content: Less than 0.3%
• CBD:THC Ratio: ~30:1
• Lineage: Unknown (Stanley Brothers proprietary genetics)
• Best For: Seizure disorders, zero-THC therapeutic needs, anxiety

Charlotte’s Web is arguably the most famous CBD strain in the world – and for good reason. It was developed by the Stanley Brothers in Colorado for Charlotte Figi, a young girl with Dravet syndrome, a rare and severe form of epilepsy. The strain dramatically reduced her hundreds of weekly seizures, and her story became a turning point for CBD awareness nationwide.

With a CBD:THC ratio of about 30:1, Charlotte’s Web delivers powerful therapeutic benefits without any psychoactive effects. It’s an excellent option for managing seizures, inflammation, and chronic pain. You’ll find it mostly in oils, tinctures, and capsules from the Charlotte’s Web brand, though flower is available in some markets.

Charlotte’s Web sparked mainstream interest in medical cannabis and helped normalize non-intoxicating CBD products for skeptical lawmakers and the general public alike.

• Type: Sativa-dominant hybrid
• CBD Content: 14-20%
• THC Content: 1-6%
• CBD:THC Ratio: Up to 20:1
• Lineage: Cannatonic x Ruderalis
• Dominant Terpenes: Myrcene, pinene, caryophyllene

ACDC is one of the best medical marijuana strains for people who need to stay functional. With a CBD:THC ratio of up to 20:1, it delivers clear-headed, uplifting relief without cognitive fog. Users consistently report fast-acting pain reduction, improved focus, and noticeable anxiety management.

The flavor profile is earthy and sweet with hints of cherry and lemongrass. ACDC is a phenotype of the well-known Cannatonic strain, so if your dispensary doesn’t carry ACDC specifically, ask about other Cannatonic phenos with high CBD testing.

Pro tip: ACDC is one of the most cited strains in medical cannabis user reviews for daytime anxiety relief. If impairment is a concern, this is the logical starting point.

• Type: Sativa-dominant (75% sativa)
• CBD Content: 7-15%
• THC Content: 4-10%
• CBD:THC Ratio: 5:2
• Lineage: Colombian Gold x Thai Landrace x Swiss Landrace x Nepali Landrace
• Dominant Terpenes: Myrcene, pinene, caryophyllene
• Best For: Pain relief with mild euphoria, social situations, creative work

Harlequin is one of the most popular CBD strains available – and it’s earned that reputation through decades of consistent performance. The 5:2 CBD:THC ratio means you’ll feel something: a calm, clear-headed happiness that makes everything a little more enjoyable without overwhelming you.

Descended from Colombian Gold, Nepali indica, and Thai and Swiss landrace strains, Harlequin has complex genetics that show in its flavor – earthy musk with sweet mango notes. It’s a multiple Cannabis Cup award winner for CBD content in both flower and concentrate form, and it’s also a parent strain behind several other entries on this list.

If you want relief paired with a mild, functional uplift, Harlequin is hard to beat.

• Type: Hybrid
• CBD Content: 6-17%
• THC Content: 3-15%
• CBD:THC Ratio: Ranges from 5:1 to 1:1 (phenotype dependent)
• Lineage: MK Ultra x G13 Haze

• Best For: Relaxation, muscle tension, mood boost, migraines

Cannatonic is the parent strain behind many CBD-dominant cultivars, including ACDC. Bred by Spanish seed company Resin Seeds, it crosses the heavy indica MK Ultra with the uplifting G13 Haze. What makes Cannatonic interesting is its wide phenotypic range – some expressions test at 1:1 with noticeable THC, while others lean heavily toward CBD.

The best CBD phenotypes deliver short-lived, mellow relaxation with a slightly earthy, citrusy flavor. It’s a solid choice for migraines, muscle spasms, and general stress. If you’re exploring the differences between CBD and THC and want to experiment with different ratios, Cannatonic’s diversity makes it a great lab.

• Type: Hybrid (60% sativa / 40% indica)
• CBD Content: Up to 20%+
• THC Content: Less than 1%
• CBD:THC Ratio: Up to 24:1
• Lineage: Harle-Tsu x ACDC
• Dominant Terpenes: Myrcene, pinene, caryophyllene
• Best For: Deep relaxation, chronic pain, inflammation, sleep prep

Named after cannabis activist and CBD pioneer Lawrence Ringo, this strain is a cross of Harle-Tsu and ACDC – essentially a CBD superstar bred from two CBD superstars. The 24:1 CBD:THC ratio in its most potent phenotype makes it one of the highest-CBD strains you’ll find anywhere.

Ringo’s Gift produces full-body relaxation with a mild cerebral warmth. The flavor is sweet mint with earthy undertones. It’s gained popularity in Barcelona’s cannabis clubs and among patients who want near-zero THC.

Multiple phenotypes exist with ratios ranging from 1:1 to 24:1, so always check lab results before purchasing. The high-CBD phenotype is the one most people seek out.

• Type: Indica-dominant hybrid
• CBD Content: 5-15%
• THC Content: 1-5%
• CBD:THC Ratio: ~5:1
• Lineage: Harle-Tsu x Sin City Kush
• Dominant Terpenes: Pinene, myrcene, caryophyllene
• Best For: Muscle spasms, chronic pain, insomnia, nausea

Stephen Hawking Kush is the second release in Alphakronik Genes’ Great Minds seed series, and it lives up to the name. This indica-dominant hybrid combines CBD-rich Harle-Tsu genetics with the potent Sin City Kush, resulting in a strain that’s both relaxing and functional.

Three known phenotypes exist, all featuring vibrant cherry and berry flavors with a minty note. The calming, relaxing effects help manage pain and suppress nausea while keeping sedation manageable. It’s a unique CBD cut that offers both heady and soothing effects – versatile for daytime or evening use depending on the pheno.

• Type: Hybrid (60% indica / 40% sativa)
• CBD Content: Up to 24%
• THC Content: Less than 1%
• CBD:THC Ratio: 20:1
• Lineage: Harlequin x Sour Tsunami
• Dominant Terpenes: Myrcene, pinene, terpinolene
• Best For: Severe pain, anxiety, staying functional under pressure

Harle-Tsu was handcrafted by the late Lawrence Ringo of the Southern Humboldt Seed Collective by crossing two CBD pioneers: Harlequin and Sour Tsunami. The result is a strain with some of the highest CBD concentrations available, regularly testing above 20%.

Think of it like a natural aspirin – it relieves pain, loosens stiff muscles, and eases anxiety without producing any high or body heaviness. The flavor is sweet with earthy, tea-like notes. It’s excellent for those who need to perform complex mental tasks or navigate high-stress environments while managing symptoms.

One of Harle-Tsu’s biggest advantages for growers is that about 75% of seeds express the high-CBD phenotype, making it more reliable than many other CBD genetics.

Pro tip: If you’re dealing with chronic pain but need to keep a clear head, Harle-Tsu is arguably the best option on this entire list.

• Type: Indica-dominant hybrid
• CBD Content: 5-10%
• THC Content: 5-10%
• CBD:THC Ratio: ~1:1
• Lineage: Shark Shock CBD variant
• Dominant Terpenes: Myrcene, caryophyllene, limonene
• Best For: Balanced effects, pain with mild high, evening relaxation

CBD Shark stands out on this list because of its 1:1 CBD:THC ratio. Unlike the other entries that minimize THC, CBD Shark embraces it equally – giving you a calming, pain-relieving experience with a gentle psychoactive layer.

This is a solid pick for people who want more than pure CBD but find high-THC strains too intense. The balanced ratio means CBD actively moderates the THC effects, reducing the chance of anxiety or paranoia while still providing noticeable body relaxation. It’s a good evening strain when you want to unwind with a mild buzz.

The entourage effect is on full display with 1:1 strains like CBD Shark – THC and CBD working together tend to produce a more well-rounded experience than either cannabinoid alone.

• Type: Sativa-dominant hybrid
• CBD Content: 15-20%
• THC Content: Less than 1%
• CBD:THC Ratio: ~15:1
• Lineage: Suver Haze x Early Resin Berry
• Dominant Terpenes: Myrcene, caryophyllene, humulene
• Best For: Energy, focus, morning use, productivity

Lifter does exactly what the name promises – it lifts you up. This sativa-dominant hybrid delivers energy, focus, and motivation without any psychoactive effects. It’s become one of the most popular CBD strains for daytime use, and with good reason.

The aroma is… distinctive. Think funky cheese with a classic gassy undertone. Not for everyone nose-wise, but the effects are hard to argue with. Users describe it as the perfect wake-and-bake strain for people who don’t want to get high – all the energy and enthusiasm without the head rush or anxiety.

Lifter is widely available as hemp flower online, making it one of the most accessible high-CBD strains regardless of your state. If your morning coffee isn’t cutting it, this might be worth adding to the rotation.

• Type: Indica-dominant hybrid
• CBD Content: 8-15%
• THC Content: Less than 1%
• CBD:THC Ratio: ~13:1
• Lineage: Cannatonic x Afghan Skunk
• Dominant Terpenes: Myrcene, pinene, caryophyllene
• Best For: Evening relaxation, anxiety, sleep support

Remedy does exactly what its name suggests – gentle, therapeutic relief without psychoactive effects. This cross of Cannatonic and Afghan Skunk delivers a lemon-pine aroma with sweet, floral undertones and yellow-tinted buds wrapped in crystal trichomes.

Users report feeling less tension, lower anxiety, and a general sense of well-being without drowsiness or mental fog. It’s a solid choice for unwinding after a long day or for people new to cannabis who want to start with something that won’t overwhelm.

Remedy has earned a strong reputation on user review platforms and consistently ranks among the top CBD strains for mellow, no-frills relaxation.

• Type: Indica-dominant hybrid
• CBD Content: 5-10%
• THC Content: 5-10%
• CBD:THC Ratio: ~2:1
• Lineage: Critical Mass CBD variant
• Dominant Terpenes: Myrcene, caryophyllene, limonene
• Best For: Chronic pain, muscle spasms, insomnia with mild high

Critical Mass CBD is an indica-dominant hybrid with a roughly 2:1 CBD:THC ratio. It’s great for easing chronic pain, muscle spasms, and insomnia, thanks to its blend of physical relaxation and mental alertness. If you like just a hint of THC with your relief – enough to take the edge off without getting properly high – this could be your go-to.

If CBD isn’t quite enough and you want more of a kick, THCA flower might be worth exploring. THCA is the precursor to THC – when heated, it converts into the psychoactive compound that produces the traditional cannabis high. Check out our guide to the strongest THCA strains or the best CBD flower strains of 2025 for more options across the potency spectrum.

CBD interacts with your endocannabinoid system (ECS) – a network of receptors that helps regulate mood, pain, sleep, appetite, and immune response. Unlike THC, which binds directly to CB1 receptors in the brain, CBD works more indirectly by modulating receptor activity and influencing your body’s own endocannabinoid production.

This is why CBD doesn’t get you high but can still deliver noticeable effects. It’s also why CBD can counteract some of THC’s less desirable effects – like paranoia and anxiety – when the two compounds are consumed together. This synergistic relationship is a core part of the entourage effect.

Research into CBD’s therapeutic potential is still evolving. Early studies and widespread user reports suggest benefits for pain management, anxiety reduction, anti-inflammatory effects, seizure reduction, and improved sleep quality.

CBD flower refers to cannabis buds rich in CBD, potentially with varying levels of THC. In legal cannabis markets, CBD flower can have more than 0.3% THC.

Hemp flower is legally defined as cannabis containing 0.3% THC or less under the 2018 Farm Bill. Many strains on this list – Lifter, Remedy, and others – are available as hemp flower, purchasable online in most states without a medical card.

THC flower is the traditional “weed” bred for high THC. For a deep dive into those, check out the 27 best weed strains.

The legal distinction matters. Hemp-derived products with less than 0.3% THC are federally legal. Cannabis with more than 0.3% THC remains a Schedule I substance under federal law, though many states have legalized it recreationally or medically. As of late 2025, an executive order directed reclassification of cannabis to Schedule III, but that process is still ongoing.
