Camphene — the cannabis terpene in depth

Camphene is a monoterpene with molecular formula C₁₀H₁₆ and a boiling point of 159 °C. In cannabis, typical levels are 0.01–0.3 % dry weight. Outside the plant it is found in fir, cypress, nutmeg, rosemary. Within the cannabis aroma landscape, Camphene is an important contributor, dominant in chemovars such as Ghost OG, ACDC, Strawberry Banana, OG Kush.

It usually co-occurs with myrcene and caryophyllene — the exact ratios determine the sensorial nuance.
