Clusters
Cannabis classification by chemistry, not folklore
Science-Based Classification
Find Your Chemical Match
Each cluster represents a distinct terpene profile identified through k-means analysis of 420 cannabis samples.
The Science
Beyond Indica vs Sativa
A modern approach to cannabis classification based on peer-reviewed research.
Chemical Fingerprints
The 2025 German study by Herwig et al. analyzed 420 medical cannabis products using k-means clustering on 9 key terpenes that explain 86% of chemical variation. The result: 6 distinct clusters that predict effects far better than plant morphology ever could.
Myrcene, caryophyllene, limonene, linalool, humulene, pinene, terpinolene, fenchol, and ocimene.
Silhouette score 0.68, Davies-Bouldin index 0.72 - statistically robust clustering.
