Some cannabis strains disappear almost as quickly as they become popular. Others stick around for decades, influencing generations of breeders and leaving their mark on hundreds of different varieties.
Haze belongs firmly in that second group.
Long before Cookies, Gelato and Runtz became household names in the cannabis world, Haze was already making a name for itself. Its distinctive spicy, citrus and incense-like aromas helped it stand out, while its unusual genetic background attracted considerable attention from breeders.
Today, Haze cannabis genetics can be found in everything from established Amsterdam classics to modern fruity hybrids. But its story began thousands of miles away, in California during the 1970s.
And like many famous cannabis strains, not everything about its origins is as straightforward as you might think.
Where Did Haze Cannabis Genetics Originate?
The evolution of Haze genetics started in California during the early 1970s, when cannabis breeding was still a relatively small and informal scene.
At the time, American enthusiasts were becoming interested in cannabis varieties originating from different parts of the world.
Seeds from countries such as Colombia, Mexico, Thailand and India were finding their way into California, bringing genetic characteristics that were unfamiliar to many local collectors.
Original Haze first gained attention in California during the early 1970s, at a time when cannabis breeders were experimenting with landrace varieties brought back from different parts of the world. The strain became associated with its distinctive spicy, earthy aromas and strong sativa characteristics, setting it apart from many other varieties available at the time. Although much of its early development remains surrounded by conflicting accounts, Haze would eventually become one of the most influential genetic lines in modern cannabis breeding. Humboldt Seeds takes a closer look at the early history of Original Haze, including the people and genetics believed to have shaped its development.
Some of these imported varieties had remarkably different aromas, appearances and other characteristics.
It was from this collection of international genetics that Original Haze began to emerge.
The strain is most commonly associated with the Santa Cruz area of California, although the exact details of its creation remain debated.
What we do know is that Haze became one of the most influential sativa-associated genetic families to emerge from that period.
Who Created the Original Haze Strain?
This is where the history gets a little complicated.
One of the most frequently repeated stories credits a pair of California breeders known as the Haze Brothers.
According to this account, they experimented with several imported cannabis varieties, eventually developing the genetic family that became known as Original Haze.
The story behind Original Haze isn’t quite as clear-cut as many people believe. Although the legendary Haze Brothers of Santa Cruz, California, are often credited with creating the strain during the early 1970s, its exact origins remain disputed. Different breeders have shared conflicting accounts of the people involved and the genetics used, making it difficult to establish a definitive history. The disputed origins of Original Haze are explored in more detail by Weedmaps, including the stories that helped shape one of cannabis breeding’s most influential genetic families.
However, there are few surviving contemporary records confirming exactly who created the original line.
Other important names associated with its history include David Watson, better known as Sam the Skunkman, who helped preserve and distribute early Californian cannabis genetics.
The arrival of Haze genetics in the Netherlands marked an important chapter in cannabis breeding history. During the 1980s, Sam the Skunkman helped introduce influential California genetics to European breeders, including Karel Schelfhout and Nevil Schoenmakers. These connections played a significant role in bringing Haze to a wider audience and shaping the development of several well-known hybrids. Super Sativa Seed Club’s history of Haze genetics offers an interesting firsthand account of this period, including the breeders and genetic lines that helped establish Haze’s reputation in Europe.
Cannabis researcher Robert Connell Clarke provided one of the more detailed published descriptions of Original Haze in 2006.
His account describes a breeding line developed through successive crosses involving different imported sativa varieties.
Rather than presenting Haze as one simple cross, Clarke explains how different genetic contributions were introduced over several generations.
This helps explain why historical Haze selections could display such varied characteristics.
The exact identities of the original breeders may never be established beyond doubt, but their influence on cannabis history is difficult to overlook.
What Are the Original Haze Genetics?
Original Haze is generally associated with four important geographical genetic backgrounds.
Colombian Genetics
Colombian cannabis varieties were an important part of the American cannabis scene during the 1960s and 1970s.
They became associated with distinctive spicy, earthy and occasionally sweet aromas.
These South American genetic lines formed part of the early background from which Haze developed.
Mexican Genetics
Mexican cannabis also played a significant role in early American breeding.
Well-known regional names such as Acapulco Gold became established long before many of today’s commercial hybrids existed.
Mexican selections contributed to the genetic diversity available to California breeders during the period when Haze was emerging.
South Indian Genetics
South Indian varieties are another part of the ancestry described in historical accounts of Original Haze.
Robert Connell Clarke specifically described the introduction of a South Indian male into the breeding line during an early generation.
This contribution helped broaden the genetic background of the developing Haze family.
Thai Genetics
Thai cannabis became particularly influential in the history of Haze.
Traditional Thai varieties were associated with unusual, often sweet, citrus-like and spicy aromatic characteristics.
In Clarke’s description, Thai genetics were introduced in a later generation of the original breeding programme.
This was another important step in the development of Haze.
It’s worth remembering that the original line wasn’t necessarily genetically identical from one generation to the next.
The characteristics of early Haze selections depended partly on which stage of the breeding programme they came from.
How Haze Made Its Way to Amsterdam
While Haze started in California, its international reputation developed considerably during the 1980s and 1990s.
The Netherlands had become an important centre for cannabis seed breeding, with several companies preserving and developing genetic lines originally introduced from North America.
Among the names most closely associated with this period were Sam the Skunkman and Australian-born breeder Nevil Schoenmakers.
Nevil founded The Seed Bank in the Netherlands during the 1980s and became an important figure in the development of several influential cannabis hybrids.
His work with Haze genetics helped introduce the family to a much wider European audience.
Rather than concentrating exclusively on Original Haze, breeders began combining Haze selections with other established strains.
Northern Lights and Skunk became particularly important in this process.
These combinations eventually gave rise to some of the best-known varieties in cannabis history.
By the 1990s, Haze had become a major part of the Amsterdam cannabis scene.
Famous Cannabis Strains With Haze Genetics
One of the clearest signs of Haze’s influence is the number of famous strains connected to its genetic family.
Some of these varieties are now considered classics in their own right.
Neville’s Haze
Named after Nevil Schoenmakers, Neville’s Haze is one of the best-known descendants of the original Haze breeding work.
Its ancestry combines Haze selections with Northern Lights #5.
The variety became closely associated with the Dutch breeding scene and helped establish the reputation of Haze-dominant hybrids during the late 1980s and 1990s.
Super Silver Haze
Few names are more closely connected with Amsterdam’s Haze history than Super Silver Haze.
Developed through genetics associated with Haze, Skunk and Northern Lights, it became one of the defining varieties of the 1990s.
Green House Seed Company lists Cannabis Cup victories in 1997, 1998 and 1999 among its achievements.
Its reputation helped introduce Haze genetics to another generation of cannabis enthusiasts.
Amnesia Haze
Amnesia Haze became another important name in European cannabis culture.
However, its history is more complicated than it first appears.
Different breeders have released strains under the Amnesia and Amnesia Haze names, and their documented genetic backgrounds are not always identical.
Soma’s Amnesia Haze, for example, has a distinct breeding history from the original Amnesia line associated with Hy-Pro and Super Strains.
Both are important parts of the wider Haze story, but they shouldn’t automatically be treated as the same strain.
Super Lemon Haze
Super Lemon Haze brought a particularly strong citrus character into the Haze family.
Green House Seed Company developed it from Lemon Skunk and Super Silver Haze.
The result became widely recognised for its sharp lemon aroma alongside the more traditional Haze background.
It demonstrates how Haze genetics can be combined with different aromatic families while maintaining connections to older breeding lines.
What Makes Haze Genetics So Distinctive?
When people describe Haze, they’re usually talking about more than a particular strain name.
The family has become associated with several recognisable characteristics.
Perhaps the most obvious is its aromatic profile.
Traditional Haze varieties are often described as having spicy, herbal, woody or incense-like scents, sometimes accompanied by citrus or floral notes.
These characteristics can vary considerably depending on the particular selection.
The family has also historically been associated with sativa-type characteristics, although modern indica and sativa classifications don’t provide a precise measurement of genetic ancestry.
A modern strain carrying Haze genetics may look and smell quite different from Original Haze.
That’s especially true when several generations of other genetic lines have been introduced.
For collectors, this diversity is one of the more interesting aspects of the Haze family.
How Haze Influenced Blue Dream Genetics
One of the most recognisable modern strains with a Haze connection is Blue Dream.
Widely associated with California’s cannabis scene, Blue Dream combines the famous Blueberry genetic family with Haze ancestry.
It’s an interesting combination because the two families have quite different aromatic backgrounds.
Blueberry is known for its sweet, fruity characteristics, while Haze is generally associated with more herbal, spicy and citrus-like aromas.
Bringing these backgrounds together created a hybrid that became enormously popular in California and beyond.
Blue Dream subsequently influenced numerous newer varieties, extending the reach of Haze-related genetics into another generation of breeding.
We’ve covered that history in more detail in our article, Why Blue Dream Genetics Remain So Popular.
It’s a good example of how an older genetic family can continue shaping cannabis varieties decades after its introduction.
Haze Genetics in Modern Cannabis Hybrids
Even with the enormous popularity of Cookies, Gelato and other modern genetic families, breeders haven’t abandoned Haze.
Instead, some have found new ways to incorporate its characteristics into contemporary hybrids.
One interesting example is Glue Dream by Top Shelf Elite.
Top Shelf Elite developed this variety by combining Blue Dream with two of its breeding projects, Glueberry Skunk and Ancient Haze.
According to the breeder, the intention was to build on the familiar berry and Haze characteristics associated with Blue Dream while introducing greater aromatic depth and resin-related characteristics.
Glueberry Skunk contributes another fruity genetic background, while Ancient Haze brings an additional Haze-associated element to the combination.
The complete lineage is described as:
Blue Dream × Glueberry Skunk × Ancient Haze
What’s particularly interesting is the way this variety connects different generations of cannabis breeding.
Blue Dream already carries a Haze connection, while the addition of Ancient Haze introduces another line selected by Top Shelf Elite.
It’s worth noting that the name Ancient Haze alone doesn’t establish an identical relationship to the original 1970s Haze stock. That would require more detailed breeding records.
Nevertheless, Glue Dream provides a useful example of how modern breeders continue incorporating Haze-associated genetics rather than leaving them in the past.
Are All Haze Strains Related?
Not necessarily as closely as their names might suggest.
Over the decades, the word Haze has become associated with a broad collection of cannabis varieties.
Some have well-documented connections to classic breeding lines such as Original Haze, Neville’s Haze or Super Silver Haze.
Others may carry the name because of their aromatic characteristics, breeder history or more distant genetic background.
That’s why the individual strain’s parentage is important.
Two varieties both described as Haze hybrids may have quite different genetic histories.
The name provides a useful starting point, but it doesn’t tell the whole story.
The same principle applies to other major genetic families, including Kush, Skunk and Cookies.
Understanding how different genetic lines are combined can make these family connections much easier to follow. We’ve covered the subject in more detail in our guide to Understanding Hybrid Cannabis Genetics.
Why Haze Genetics Still Matter Today
Considering how quickly the cannabis market changes, the continued influence of Haze is remarkable.
Its origins date back more than fifty years, yet its genetic background remains relevant to modern breeding.
Part of that longevity comes from the distinctive characteristics associated with the original family.
But there’s another reason.
Haze became one of the foundation lines that breeders repeatedly returned to when developing new combinations.
Rather than existing as one isolated strain, it became part of a much larger family tree.
From classic Amsterdam varieties to Californian hybrids and more recent releases, the same genetic history keeps appearing in different forms.
And that’s what makes Haze such an important part of cannabis history.
Our Take at SeedMasters.com
At SeedMasters.com, we enjoy looking beyond the latest strain names and finding out where their genetics actually came from.
Haze is a perfect example of why that matters.
A modern strain might have a name that sounds completely unrelated to the old California classics, yet a closer look at its ancestry can reveal connections stretching back several decades.
We see that in varieties like Blue Dream and in newer combinations from breeders such as Top Shelf Elite.
It’s also a reminder of how much modern cannabis breeding owes to the genetic lines preserved and developed during the 1970s, 1980s and 1990s.
Without those earlier varieties, many of today’s familiar strains simply wouldn’t have the same genetic background.
For collectors interested in cannabis history, Haze is one of those families well worth learning about.
After more than half a century, its influence is still being felt.
