Which medical cannabis strain is best for migraines?
ACDC, a high-CBD cultivar with roughly a 20:1 CBD to THC ratio, is the best first choice for migraine patients who want relief without heavy intoxication. Cannabidiol is its dominant cannabinoid, and CBD is the compound most often studied for pain and headache. Harlequin, Cannatonic, Northern Lights and Blue Dream are the strongest alternatives when ACDC is not on the menu.
Strain choice matters less than ratio, terpenes and dose. A product with 10 to 20 mg of CBD for every 1 mg of THC behaves very differently from a 25% THC flower.
How the top strains compare
- ACDC: about 20:1 CBD to THC. Top pick for daytime migraine and aura.
- Harlequin: about 5:2. Balanced relief with mild psychoactivity.
- Cannatonic: roughly 1:1 to 2:1. Best for evening or severe attacks.
- Northern Lights: indica, THC dominant. Best for nausea and sleep during an attack.
- Blue Dream: sativa hybrid, THC dominant. Best in low doses that keep you functional.
1. ACDC (best overall)
ACDC tests high in CBD and low in THC, so it rarely triggers anxiety or racing thoughts. Many patients vaporize it at the first sign of an aura or tension build-up rather than waiting for pain to peak.

2. Harlequin (best balanced option)
Harlequin usually lands near 5:2 CBD to THC and shows myrcene and pinene in its profile. The small amount of THC adds a body effect that CBD alone may not produce.

3. Cannatonic (best for evening attacks)
Cannatonic ranges from 1:1 to 2:1 and is often sold as a vape cartridge or tincture. Its sedative lean suits nighttime migraines that arrive with neck tension.
4. Northern Lights (best for nausea and sleep)
This indica leans on THC and myrcene, which helps with the nausea and light sensitivity that follow many attacks. Keep the dose low, since high THC may worsen rebound headaches in some people.
5. Blue Dream (best in microdoses)
Blue Dream is THC dominant but energizing, so a 1 to 2 mg microdose can take the edge off without sedation. Larger doses often backfire by raising anxiety.
Which terpenes help migraines?
Terpenes shape the effect as much as cannabinoids do. Check these on a batch lab report.
- Myrcene: sedating, used for pain and sleep.
- Beta-caryophyllene: binds CB2 receptors and supports inflammation control.
- Linalool: calming, linked to reduced tension.
- Pinene: may support alertness and easier breathing.
Go easy on heavy limonene or terpinolene if strong smells or stimulation set off your attacks.
How do you dose medical cannabis for a migraine?
- Start at 1 mg THC and 10 to 20 mg CBD, then wait two hours.
- Use vaporized flower or an oil for faster onset during an attack.
- Log attacks, dose, ratio and terpenes for four to six weeks.
- Raise the CBD share before you raise THC.
Is there real evidence for cannabis and migraines?
Evidence is limited. Reviews indexed by the National Library of Medicine report mixed results from small studies of cannabis in headache disorders. The American Migraine Foundation notes that most support is anecdotal, and the FDA has not approved any cannabis product for migraine.
Cannabis remains a Schedule I substance under federal US law, and a state medical card is required where programs exist. Hemp-derived CBD with less than 0.3% THC is federally legal and sold in most states without a card.
What if you cannot get medical cannabis?
A full-spectrum hemp CBD oil delivers the CBD side of the ratio without a dispensary trip. Choose products with a batch-specific lab report showing cannabinoid and terpene content.
