Thujene

Thujene is a minor monoterpene found in trace amounts across many cannabis chemotypes, though it rarely constitutes a significant portion of the terpene profile. It is structurally similar to α-pinene and is commonly associated with herbal, woodsy, and slightly spicy aromatic notes. Thujene appears in various plant families beyond cannabis, including sage and thuja species, contributing to their characteristic scents. In cannabis breeding contexts, thujene is often tagged as a secondary compound that may contribute to complex aromatic blends rather than define them. Its presence is typically identified through detailed chromatographic analysis rather than sensory evaluation alone. Lineage records frequently report thujene in small quantities across diverse strain families, though breeders do not typically select for or against this compound specifically.

Breeders working in terpene-focused selection programs may encounter thujene as part of broader monoterpene profiles. Its low abundance means it generally plays a minor role in breeding decisions compared to dominant terpenes like myrcene or limonene.
