Marijuana can be piney, earthy, gassy, spicey, or exude a veritable fruit basket of odors including: banana, melon, orange, lemon, tangerine, and more. And while most of these fragrances are considered pleasing by most, one scent in particular, skunk, has a decidedly unpleasant connotation. The variety of smells found in cannabis are largely produced by terpenes, a class of aromatic chemicals found in many plants and even some insects.
More than 20,000 different terpenes have been identified, making them the largest category of plant compounds discovered. At least 200 different terps have been found in cannabis, although only a handful are the most dominant. Pinene can give pot a pine-like fragrance, while caryophyllene is peppery. Limonene has a citrusy scent and terpinolene is fruity. Myrcene, the most prevalent cannabis terpene, is earthy or musky, a trait that is partly responsible for the skunky funk of some strains. Some less common terpenes, however, give off the odor of a different class of chemicals known as thiols.
These compounds have a sulfurous smell that can be reminiscent of rotten eggs, fuel, or even farts. Thiols are also responsible for the unique and very recognizable stench of skunk spray, a defense mechanism that can help keep the animal safe from predators. Strains of cannabis with terpenes that have an aroma similar to these thiols are often referred to as skunky or skunk weed . There are many strains of cannabis that express the skunky smell of these terpenes. Skunk weed varietals got their start in the 1970s with the introduction of Skunk #1 by Sacred Seeds, a group of breeders in Northern California led by David Watson, also known as Sam the Skunkman. Skunk #1 is a cross of short, bushy Pakistani and Afghani varietals cultivated for hash, and tropical strains from Asia and South and Central America. Watson was one of the first breeders who recognized that, while THC was the component of cannabis mainly responsible for the high it imparts, terpenes were also important and could intensify and modify the plant's psychoactive effects through the entourage effect. As a result, when evaluating breeding stock for his next cross, Sam the Skunkman often let the aroma of these potential parents be his guide. Gallery — Cannabis Up-Close and Personal: Besides their inherent skunkiness, the flowers of Skunk #1 also impart musky and earthy aromas with subtle floral and fruity notes, while the flavor of the strain is generally woodsy, sweet, and fruity. The clear-headed high of this original skunk weed can be somewhat euphoric, heighten creativity, and relieve stress. Medical marijuana patients have reported success using the strain to treat pain, asthma, glaucoma, stress, nausea, vomiting, and as an appetite stimulant. The success of Skunk #1 made it an ideal strain to breed with other plants in order to create different varieties of skunk weed. After serving a stint in prison and being released in 1982, Watson moved to the Netherlands, taking several kilos of seeds with him. He then resumed his breeding career, and started the seed company Cultivator’s Choice in Amsterdam. Soon, other Dutch breeders were also offering their own strains of skunk weed, with varieties such as Super Skunk, Jack Herer, Northern Lights, and Early Girl making their debut on the cannabis scene. Today, these varieties have become popular genetics for breeders who have produced literally hundreds of strains with skunk in their name or terpene profile, including Skunk Dawg, Lemon Skunk, Skunky Diesel, Skunk Haze, and (my personal favorite) Thelonious Skunk. The word "skunk" can refer to more than just genetic terms for cannabis, too. For people who don’t use cannabis (and even some who do partake), all varieties of cannabis smell skunky. To a certain extent this is true, although more experienced cannaphiles will appreciate the other aromas and notes present in a particular strain’s bouquet. In the United Kingdom, the term "skunk weed" has taken on a more generic meaning. There, skunk doesn’t refer to the aroma of particular strains of marijuana. Rather, it is a moniker that designates highly potent pot. Just about any kind of super-stony sensimilla flower that is cultivated for smoking will qualify as skunk weed across the pond.
Despite the nuances of meaning that the term skunk weed can have from one person to the next, one thing is a given: When you smell that sweet stank, you’re sure to be in for a good time. It’s hard to ignore the similarities in the aroma of cannabis and skunk – they can be hard for some people to distinguish (though many people do so easily). Depending on where you are, it’s not too difficult to infer what you’re smelling. In the middle of a neighborhood or city – where skunks and pot intermix – it’s a bit more of crapshoot.
Most people don’t care what they’re smelling – skunk, cannabis, a skunk smoking cannabis – it makes no difference. But it does elicit curiosity – out of all the animals on earth, why does marijuana smell like the most odorous one? Cannabis, especially to the trained nose, doesn’t come with one odor – different strains elicit different aromas. But many of them – while they may have hints of other things like citrus or pine – do have a foundation that smells skunky. Marijuana is filled with terpenes , organic compounds that are found in a variety of plants (fun fact: some insects (such as termites) also emit terpenes).
