If you want CBD without much of a high, start with the ratio printed on the label. Strains that test at 20:1 CBD to THC or higher, such as Charlotte's Web, ACDC, Harle-Tsu, Remedy, and Ringo's Gift, typically land under 1% THC with 12% to 22% CBD. Hemp flower like Cherry Wine, Lifter, Elektra, and Suver Haze stays under the federal 0.3% THC limit, which makes it the closest thing to THC-free at a normal dose. Anything at 1:1 or 2:1, such as Cannatonic, Pennywise, or Harlequin, can still get you high if you smoke or vape enough of it.

How the CBD:THC ratio actually works
The ratio is a lab result, not a marketing promise. A 20:1 label means that batch showed 20 parts CBD for every 1 part THC. Two harvests of the same strain from different growers can look nothing alike, and phenotype matters. Cannatonic is the classic example: some cuts run near 1:1 and others push 2:1 or higher.
CBD Hemp Strains for Sleep: What the Research Shows
- 20:1 and up: CBD-dominant, THC usually under 1%. Weak head high, better for daytime and for people who dislike THC.
- 5:1 to 10:1: A little THC buzz at higher doses. Common for people who want body relief with a clear head.
- 2:1: Noticeable THC effects. A reasonable middle ground for anxiety or pain at low doses, too much for a first-timer.
- 1:1: Balanced. Euphoric and possibly intoxicating. Some people find THC's rough edges softened by the CBD.
The list, sorted by THC load
High ratio, low THC flower
- Charlotte's Web: the reference strain. Often 12% to 20% CBD, under 1% THC. Mild, earthy, rarely intoxicating.
- ACDC: can hit 16% to 24% CBD with around 0.5% to 1% THC. One of the strongest CBD-only picks on most menus.
- Harle-Tsu: a Harlequin and Sour Tsunami cross. Usually 18% to 22% CBD, under 1% THC, often listed near 20:1.
- Remedy: around 10% to 15% CBD with trace THC. Popular for evening use and body comfort.
- Ringo's Gift: 15% to 25% CBD, often under 1% THC, though 1:1 phenos exist. Check the batch.
- Therapy: high CBD, low THC, and usually sold as a calm, non-psychoactive option.
- Sour Tsunami: roughly 10% to 16% CBD. THC varies more than people expect, so read the label.
Hemp flower (under 0.3% THC by law)
If you need to stay under a legal THC ceiling, hemp cultivars are where that happens. Cherry Wine, Lifter, Elektra, Suver Haze, and Hawaiian Haze are the ones I see most. They are sold as hemp rather than marijuana, which means the THC number is capped federally instead of left to the grower's discretion.
Highest Yielding CBD Strains: Indoor and Outdoor Guide
Middle ground (2:1 to 5:1)
- Cannatonic: anywhere from 1:1 to 2:1 depending on the cut, with CBD in the 6% to 17% range.
- Harlequin: usually around 5:2, meaning 8% to 16% CBD and 4% to 7% THC. A solid daytime hybrid for people with some tolerance.
- Stephen Hawking Kush: often lands near 2:1. Relaxing without being heavy.
- Critical Mass CBD: commonly 1:1 to 2:1, and it leans sedating.
Balanced 1:1
- Pennywise: roughly equal CBD and THC, both in the 8% to 12% range.
- Sweet and Sour Widow: a 1:1 that many people use for pain and appetite.
What to check before you buy
- Ask for the batch lab report, not the strain description. You want total THC, total CBD, and the testing date.
- Look for total THC, which includes THCA. A jar can read 0.4% THC and still hit harder than that number suggests.
- Check the package date. Both CBD and THC degrade after months of poor storage.
- Start low. With a 1:1 strain, one or two puffs is a real dose for a new user.
Cautions worth knowing
CBD is not inert. It competes with some liver enzymes, so it can raise blood levels of blood thinners, seizure medications, and a handful of other prescriptions. Talk to your doctor or pharmacist if you take anything daily. Hemp flower can also trip a urine drug test, since even 0.3% THC accumulates with regular use. Skip THC flower entirely if you are pregnant, under 21, or about to drive.
