Origin & Genetics
Few cannabis strains carry the cultural and medical weight of Charlotte's Web. Developed in Colorado around 2011–2012 by Joel Stanley and his six brothers — collectively known as the Stanley Brothers — this proprietary hemp cultivar was not bred for recreational enjoyment. It was engineered with a singular mission: to produce massive quantities of cannabidiol (CBD) while keeping THC levels far below the psychoactive threshold.
The strain's genetics remain closely guarded by CW Hemp (now Charlotte's Web Holdings), but what is known is that it was selectively bred from an industrial hemp variety and a high-resin cannabis strain to achieve an extraordinary cannabinoid ratio. The result was a plant that tested at under 0.3% THC while yielding 15–20% CBD — an almost unheard-of profile at the time.
The strain's name honors Charlotte Figi, a young girl from Colorado who was suffering up to 300 grand mal seizures per week due to Dravet syndrome, a severe and treatment-resistant form of childhood epilepsy. After her parents began administering a Charlotte's Web CBD oil tincture in 2012, her seizures dropped dramatically — reportedly to just 2–3 per month. The story was featured on CNN's landmark 2013 documentary Weed with Dr. Sanjay Gupta, and the resulting public awareness transformed both the medical cannabis and hemp industries overnight.
Charlotte's Web is not a marijuana strain in the traditional sense — it's a hemp cultivar, federally legal in all 50 states under the 2018 Farm Bill, though state-level CBD regulations still vary.

"Charlotte's Web didn't just change one little girl's life — it changed the entire conversation about what cannabis can do as medicine, and it forced policymakers, physicians, and the public to take CBD seriously for the first time."
Cannabinoid & Terpene Profile
Charlotte's Web is defined by its remarkable cannabinoid ratio. The CBD content typically ranges from 15% to 20%, making it one of the most CBD-dense hemp cultivars commercially available. THC remains at or below 0.3% — the federal legal ceiling for hemp. Minor cannabinoids such as CBG (cannabigerol) and CBC (cannabichromene) are also present in meaningful concentrations, contributing to what researchers call the entourage effect — the synergistic interaction of cannabinoids and terpenes.
The terpene profile of Charlotte's Web is mild but distinctive, leaning earthy, piney, and faintly floral. Learn more about how terpenes shape your cannabis experience in our terpene guide.
| Terpene | Typical % Range | Aroma/Flavor | Effects & Benefits |
|---|---|---|---|
| Myrcene | 0.20% – 0.45% | Earthy, musky, herbal | Calming, sedating, muscle relaxation, anti-inflammatory |
| Caryophyllene | 0.15% – 0.35% | Spicy, peppery, woody | Anti-inflammatory, anxiety relief, pain management; binds to CB2 receptors |
| Pinene (Alpha) | 0.10% – 0.25% | Fresh pine, forest air | Mental clarity, focus, bronchodilator, memory retention |
| Linalool | 0.05% – 0.15% | Floral, lavender-like | Anxiolytic, sleep support, neuroprotective potential |
| Limonene | 0.05% – 0.12% | Citrus, lemon peel | Mood elevation, stress relief, antifungal properties |
The dominance of myrcene gives Charlotte's Web its grounding, earthy character, while caryophyllene adds notable anti-inflammatory potential — caryophyllene is unique among terpenes because it directly activates the body's CB2 endocannabinoid receptors. Alpha-pinene contributes mental clarity and counters any sedative tendency, keeping the overall experience clear-headed rather than foggy.
Effects of Charlotte's Web
Because THC is essentially absent, Charlotte's Web produces no psychoactive high. Instead, users experience a subtle but appreciable shift in their baseline state — a gentle easing of tension, a quieting of anxious thoughts, and a soft physical relaxation that doesn't impair function. Effects can vary depending on the consumption method (oil tincture, capsule, topical, or smokable flower). Visit our effects guide for a deeper look at how different cannabinoid ratios shape the experience.
Onset: When consumed as an oil tincture under the tongue, effects typically begin within 15–45 minutes. Inhalation (for those using the hemp flower form) produces onset within 5–10 minutes. Capsules and edibles may take 60–90 minutes.
Peak: Effects generally peak around 1–2 hours after consumption.
Duration: Most users report effects lasting 3–6 hours, depending on dose, individual metabolism, and consumption method.
Mental Effects
Charlotte's Web is frequently described as producing a calm, clear-headed focus. Anxiety tends to diminish gradually rather than disappear suddenly. Many users report a quiet reduction in racing thoughts, an ability to concentrate more easily, and a gentle sense of emotional steadiness. Unlike high-THC strains, there is no risk of paranoia, cognitive impairment, or dissociation. It is considered an ideal daytime option for those who need to remain fully functional while managing anxiety, stress, or chronic discomfort.
Physical Effects
Physically, Charlotte's Web tends to produce a mild but perceptible body relaxation. Muscle tension eases, inflammatory discomfort may lessen, and a general sense of physical ease settles in. The myrcene and caryophyllene terpenes contribute meaningfully to these body-focused effects. Some users with chronic pain conditions report meaningful relief, though individual responses vary considerably. At therapeutic doses, there is no sedation — though very high doses may promote sleepiness in some individuals, making it useful as a pre-sleep relaxation tool as well.
Charlotte's Web vs. Similar Strains
