Why does weed smell like a skunk
The parlance of pot is chock-full of terms that are used to describe the various aromas created by cannabis. 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. But what exactly is skunk weed? And why does it smell that way?
Terpenes Are the Key
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.
Strains of 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.

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.
Other Meanings of Skunk Weed
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.
Cannabis flower has more unique scents than the rainbow has colors. But why does weed sometimes smell like a skunk?
The Fragrance of Marijuana Before and After Consumption
Marijuana is the dried leaves and flowers of the cannabis plant. Cannabis has psychoactive and medicinal properties because of its chemical makeup.
Marijuana can be rolled up in a handmade cigarette (a joint), in a cigar, or in a pipe (a bong). It can be used for pain relief, to treat anxiety, or for recreation.
In many states, the sale and use of marijuana without a prescription is still illegal.
You can usually tell if someone has been smoking marijuana by detecting the scent of piney, slightly skunky grass that smoked cannabis leaves behind.
But figuring out for sure if what you’re smelling is weed can be a little difficult if you aren’t attuned to the scent. Various strains of marijuana can smell different from each other, making it even more complicated.
This article will cover what marijuana smells like in different stages of its use and consumption, as well as some differences between strains.
The strongest factor in the way marijuana smells is the age of the cannabis plant when it’s harvested. Cannabis that’s harvested earlier in its life cycles has a milder, less skunky scent.
It’s also less powerful when you smoke it. Cannabis that grows older before it’s picked and dried will have a stronger odor.
Organic compounds called terpenes are found in all plants, including cannabis. Myrcene (mango), pinene (pine), and limonene (lemon) are terpenes found in some strains of cannabis.
Terpenes change the scent of marijuana. For example, cannabis strains with pinene will smell more like pine.
Marijuana plants smell similar during the growing process and when they’re harvested and dried. They give off a slightly weedy, piney “skunk” scent that gets stronger as the plant grows older.
When cannabis flowers and blooms, the scent becomes powerful.
Indica vs. sativa
For decades, botanists and marijuana connoisseurs claimed that indica and sativa are different species with distinctly different effects on the body. Indica strain smells more acrid, while sativa smells more spicy or sweet.
But it would appear, at least to some experts, that there’s no way to smell the difference between indica and sativa definitively. Part of the reason is that there’s a lot of crossbreeding between these two particular strains.
However, one small study did find that participants who had purchased weed within the prior several months were able to smell the difference between several different strains of marijuana.
Marijuana consumers describe the scent of the plant as earthy, herbal, and woody. Sometimes the plant scent carries notes of lemon, apple, diesel, or plum.
Dried marijuana smells a lot stronger than some other dried plants.
When you’re smoking marijuana, the natural scent of the cannabis scent is amplified by the smoke it creates. Fire, smoke itself, ash, and the smell of rolling paper add additional layers to the scent.
When a person is smoking cannabis, notes of lemongrass, pine, fire, and wood may stand out. The distinct “skunk” smell of marijuana is often reported.
