Let me re-iterate: the stench in skunk weed ~is~ from terpenes. Skunks produce thiols, Cannabis does not. Terpenes in skunk weed strains simulate the smell of skunks (and thiols). Cannabis also simulates about 500 other things out there in the world of smells from over 200 (and counting) different terpenes and terpinoids. In Cannabis, the terpene myrcene with several other terpenes result in the smell of skunk weed.
But hey, do not believe me! No no no no. Here are four references:
Myrcene, another terpene present in numerous cannabis varietals, is a sedative, a muscle relaxant, a hypnotic, an analgesic (painkiller) and an anti-inflammatory compound. This musky terpene contributes mightily to the infamous “couch-lock” experience and is the one that gives off the skunky aroma.
So what is the link between terpenes and thiols that cause some marijuana strains to smell like skunk? The answer is that it’s rather coincidental. Some of the terpenes present in cannabis happen to smell like the thiols in skunk spray.
There is no relationship between thiols and terpenes. However, there are some terpenes that smell like thiols.
Many terpenes can smell like thiols, thus creating a skunky aroma.
