Results show that the most pungent variety of cannabis, Bacio Gelato, also had the highest concentration of VSCs. The team examined the flowers from 13 different types of cannabis plants using a custom 2D gas chromatography system with three different kinds of smell detectors.įollowing the analysis, a four-person panel ranked the pungency of each marijuana variety on a scale of 0 to 10. Since skunks use several VSCs in their foul-smelling spray, lead study author Iain Oswald and researchers suspected these particles also play a role in cannabis’ smell. Although terpenoids make up the majority of aroma compounds in marijuana, the study authors say there’s little evidence they actually produce the underlying skunky odor too. So, it’s the terpenoids that also create the skunk smell, right? Wrong. These are molecules which have a wide range of odors - from fuel to wood, to citrusy or floral.ĭifferent varieties of cannabis produce different mixtures of these molecules, giving each brand a unique scent. Previous studies into the smell of marijuana have mostly focused on substances called terpenoids. Scientists have found that the cannabis sativa plant produces over 200 unique aroma compounds. A team from California’s Abstrax Tech discovered a new family of prenylated volatile sulfur compounds (VSCs) which create this odor. Oddly enough, the compounds that produce this skunky smell in marijuana really do have a lot in common with the stench skunks spray at their enemies.
