Sources

Every lab figure on CannabisStrains comes from public datasets and published records, aggregated by CannabisStrains. Nothing is copied from other strain sites, and every figure carries a grade for how much data stands behind it. Information only, not medical advice.

How we grade the numbers

Each lab figure (THC, CBD, the minor cannabinoids and terpenes) gets a grade from A to D for how much data sits behind it: how many samples, from how many labs and places, and how recent.

AStrong data30 or more flower samples from at least 3 labs and 2 states or sources, some from the last five years, with no single lab above 30% of the data.
BGood data10 to 29 samples, or 30 or more that come from one source or state, or from 2 labs or fewer.
CLimited data3 to 9 samples. We show the range only and leave the strain out of rankings.
DNot yet measuredFewer than 3 samples, or only the breeder’s own figures. A breeder’s claim appears only as a quote.

Lab results matched to a strain by an uncertain name count at half weight and can’t lift a strain above B.
