Short answer
No strain holds the title. No lab test ranks cannabis strains by pain relief. Clinical trials test single cannabinoids and fixed ratios, not strain names. The best evidence covers products with THC and CBD near 1:1, at 10 mg to 20 mg THC per day.

What the trials tested
A 2015 meta-analysis in JAMA pooled 79 trials and 6,462 participants. People with chronic neuropathic pain and cancer pain reported a 30% or greater drop in pain scores more often on cannabinoids than on placebo. The products were nabiximols, a spray with THC and CBD near 1:1, plus dronabinol and nabilone, two synthetic THC drugs. No trial tested flower sold under a strain name.
Rough numbers: about 1 in 5 to 1 in 6 patients got that 30% drop who would not have on placebo. Evidence quality was graded moderate for neuropathic and cancer pain, low for other pain types.

Strains cited most often for pain
These names come from dispensary labels and lab reports. Potency changes by batch, grower, and test lab.
- Bruce Banner: THC 20% to 29%.
- Gorilla Glue #4: THC 20% to 28%.
- OG Kush: THC 19% to 24%.
- Northern Lights: THC 16% to 21%.
- Harlequin: THC 4% to 7%, CBD 4% to 8%.
- Cannatonic: THC 4% to 10%, CBD 5% to 12%.
- AC/DC: CBD 15% to 20%, THC under 1%.
High THC does not equal strong pain relief. Trials used 1:1 ratios to hold down side effects from THC.
Why a strain name does not settle it
One 2017 analysis of 8,505 strain listings reported mean THC of 18.7% and mean CBD of 0.5%. Genetics drift. A clone grown in two rooms gives two potency readings. A 2018 study of Washington State testing data found THC values for the same product varied with the testing facility. Label error adds more spread.
Terpenes get cited as the difference: myrcene, beta-caryophyllene, limonene. Beta-caryophyllene binds CB2 receptors in lab work. Human pain trials on single terpenes are few and small.
What to check on a label
- THC and CBD percentages, plus total cannabinoids.
- Batch test date and lab name.
- Terpene list with percentages, if the label carries one.
- Dose per unit: mg THC per piece or per puff.
Bottom line
Start with a 1:1 THC:CBD product. Measure in mg. Keep a log of dose, time, and pain score. No strain name replaces that record.
