Which Cannabis Strain Works Best for Fibromyalgia? Top Picks
No single strain works for everyone, but Harlequin is a top pick for fibromyalgia. Compare ACDC, Northern Lights, Blue Dream, and more.
Quick answer
No cannabis strain has FDA approval for migraine or for nausea. Evidence comes from small trials and from surveys. People report relief from THC-dominant flower and from CBD-dominant flower. Inhaled cannabis takes effect in 2 to 10 minutes. Edibles take 30 to 120 minutes. Start at 1 mg to 2 mg THC.
What the research shows
A 2018 survey in The Journal of Pain tracked 1,000 cannabis users. Headache ratings fell by about half after use. Migraine ratings fell by about half as well. The study was observational. It had no placebo group.
The FDA approved two synthetic THC drugs for nausea: dronabinol and nabilone. Doctors prescribe both for chemotherapy-induced vomiting. Neither drug carries a migraine indication.
Hybrid Strains for Pain Relief with Mental Clarity
THC-dominant strains
THC binds CB1 receptors in the brainstem and the trigeminal system. Lab reports list THC content, not effects. Four strains appear in patient reports.
Best Indica Strains for Body Aches and Pain: Top Picks Compared
- Northern Lights: THC 16 to 21 percent. Myrcene is the main terpene.
- Blue Dream: THC 17 to 24 percent. Pinene and myrcene dominate.
- Sour Diesel: THC 17 to 24 percent. Limonene and caryophyllene dominate.
- Granddaddy Purple: THC 15 to 23 percent. Myrcene and pinene dominate.
CBD-dominant and balanced strains
CBD does not bind CB1 receptors with the same strength as THC. It may act on inflammation and nausea through other pathways. These strains carry low THC.
- AC/DC: CBD near 19 percent, THC under 1 percent.
- Harlequin: CBD to THC ratio near 5 to 2.
- Cannatonic: CBD to THC ratio near 1 to 1.
- Charlotte's Web: THC under 1 percent, CBD 10 to 20 percent in some lots.
Nausea
THC acts on CB1 receptors in the dorsal vagal complex. This area controls the gag reflex. A 2015 review of 79 trials found cannabinoids equal to or better than standard antiemetics for chemotherapy nausea. Oral THC doses in those trials ran 2.5 mg to 10 mg.
Route and dose
- Inhalation: onset 2 to 10 minutes. Peak effect at 15 to 30 minutes.
- Oral: onset 30 to 120 minutes. Effect lasts 4 to 8 hours.
- Start at 1 mg THC. With edibles, wait 2 hours before a second dose.
- Keep a log with time, strain, THC mg, CBD mg, and pain score.
Risks and limits
Daily use can cause medication overuse headache. Case reports describe cannabis overuse headache. Stopping daily cannabis can trigger rebound headache for up to 2 weeks. CBD blocks the CYP2C19 and CYP3A4 enzymes. This changes blood levels of warfarin, clobazam, and some statins. Strain names are marketing labels. Two batches of the same name can differ in THC by 10 percentage points. Ask for a cannabinoid and terpene lab report.
What to track
Log the aura phase, pain score, nausea score, and hours of relief. Bring the log to a neurologist. A neurologist can check for interactions with triptans, CGRP inhibitors, and beta blockers.
