Tools for reading cannabis chemistry
Small tools for reading cannabis chemistry: lab results, terpene profiles and the numbers on a label. Each one shows its working, and each figure comes with its grade and the number of lab results behind it.
Terpene chart
Eight common cannabis terpenes, how often each one leads a profile, and where else they occur in nature. Built from lab-tested terpene profiles.
Total THC calculator
Turn the THCA and Δ9-THC on a label into total THC, with the working shown. Optionally see where the result sits among our lab results for a strain.
Compare two strains
Put two strains side by side: lab THC and CBD ranges, terpene profiles and how much of their profiles overlap.
Strain finder
Answer a few quick questions, including flavor and lab-tested THC range, for a shortlist of strain pages to read.
Strain chemistry map
Every strain with a graded terpene profile on one map. Strains with similar terpene chemistry sit close together.
Types of cannabinoids
The main cannabinoids labs measure, how the acid forms relate to the neutral ones, and the amounts measured in flower.
Glossary
Plain definitions of about 90 terms, from chemovar and THCA to LOQ and dry weight.

These tools describe chemistry and lab measurements. They don’t describe how any strain or compound affects people, and they aren’t advice about using cannabis. See our sources and grading for how the figures are made.
