Landrace Strains: Discover the Power

There has been a lot of talk about Landrace (LR) strains over the last few years. From Acapulco Gold to Malawi, people across the world claim to have landrace variants of many popular strains. These cultivators claim that their genetics are some of the oldest known to man. They take pride in the native, indigenous or heirloom nature of the cannabis strains under their care.
As humanities scientific understanding continues to grow, we have found that CBD may be better for treating pain and muscle spasms than THC. Without access to strains that had not been selectively bred, people would not have been able to create strains like Charlotte’s Web or LSD. Breeders needed to combine plants with new characteristics than what the market had available so they turned to the untapped potential of landrace strains.

What is a Landrace Strain?

Landrace Strain 1
A landrace strain never been crossed with a different phenotype and has grown in its natural environment for as long as people can tell. Like the Giant Tortoises of the Galapagos Islands, these plants have spent a long time in genetic isolation. Cultivators have taken the best of each generation and bred it with the next for many human lifetimes.
This isolation (and the resulting ) makes these varieties highly stable and extremely vigorous since only the best were kept. Over generations, people grew the plants that performed best for their environment. In the jungles of Durban South Africa, the plants needed to be able to grow above the trees so only tall plants grew well enough to survive.

Where Did Landrace Strains Come From?

Historical records (some dating as far back as 2900 B.C.) tell us cannabis has lived with humanity for thousands of years. Cultivated for food, fiber, and for religious and medicinal purposes, cannabis is one of the oldest known agricultural plants and has many uses.  According to the best available research, cannabis originally evolved in Central Asia and spread to nearly every region of the planet thanks to humans.
Outside of Asia, landrace strains are the result of escaped cultivars (strains that were selectively bred by humans) which gradually adapted to their environment over time. Over the centuries, other cultivars would have interbred with these feral escapees.  Due to the complex nature of the winds and plant/animal interactions, even the wild plants native to Central Asia are not believed to be untouched indigenous strains.

 Why Are Landrace Strains Important?


Not all cannabis is created equal in the eyes of growers. Plants that produce large colas full of cannabinoids like THC are traditionally prized over low yielding variants. Over generations, certain traits get bred out of or in to the genetic lines. People use this to make bigger and stronger plants than could be obtained otherwise.
This breeding method also has the effect of removing many of the less understood compounds. Since the same trichomes produce THC and CBD (and only one is psychoactive) growers selectively bred out the ability to produce CBD. That way all of the trichomes could focus on producing THC instead of some deciding to make CBD.

Where Are the Real Landrace Strains?


In today’s cannabis market people rarely see the pure landrace strains. On sites like Leafly and Cannafo, most of the sativas (the red tiled ones) are not pure sativas. Instead, they are sativa-dominant hybrids that exhibit strong sativa-like attributes. Same thing goes for indicas and hybrids. Landrace strains also exhibit these hybrid traits but to different degrees.
Landrace strains were embraced worldwide during the 1960s and 70s by growers who began collecting them in their own local gardens. Once the landrace strains were removed from their local growing environment, they became heirloom variants. For marketing reasons, most breeders don’t differentiate between landrace and heirloom.
These heirloom strains were then propagated in places like Hawaii and California. As the landrace movement grew, people who hunt for these hard to find strains became sought after. People like Arjan Roskam, founder of Amsterdam-based Greenhouse Seeds, and his colleague Franco Loja have spent millions obtaining these landrace varieties for use in their selective breeding.

What Landrace Strains Are There?

Here is a short list of some popular landrace strains:
Malawi Gold:
landrace 2Malawi Gold originated in Southeastern Africa. Grown on the shores of Lake Malawi (the third largest lake in Africa) the plant was adaptable to its local conditions. It’s genetic flexibility was perfect for the wildly changing environment which is why many phenotypes can be found in the market today. Aromas and flavors given off by the phenotypes of Malawi Gold help differentiate between the varieties. Two main phenotypes exist. One gives off a fruity smell while the other is a woody one. The fruity plants are normally smaller than the woody ones.
Afghan Kush Indica:
The plant is medium height with dark, broad leaves which makes it perfect for growing in the northern Afghani mountains. Its heavy, sweet aroma and taste mix with spices and incense to create a deep flavor. New smokers often find that this strain gives a very potent high that easily turns sedating. Perfect for people that are having trouble sleeping.
Hindu Kush Indica:
Cultivated in the Hindu Kush Mountain range for generations where it grows wild, the flowers of the fertile hillsides and valleys make the world’s finest hash. Years of selective breeding for resinous, indica-dominant plants with feral varieties have resulted in short, stocky bushes covered with huge, shiny trichomes. Known to relieve symptoms of pain, nausea, and stress while providing a pleasantly strong, earthy scent.
Lambs Bread Sativa:
Also called “Lamb’s Breath” Lamb’s Bread produces a bright green and sticky flower with a sativa dominant high. The effects have been known to help generate energy and positive introspection. Stress melts away under the warmth of the Lamb’s Bread buzz. This plant comes from Jamaica and it has been reported that Bob Marley himself enjoyed it.
There are literally tens of thousands of strains across the globe with a small percentage of them being landrace varieties. Because of the geographical nature of the landrace title, most strains retain the name of the area where they originated. Yet some places have made more of a name for themselves than others and it can be far easier to obtain their seeds or clones

Accidents and the Dangers of Driving on Weed

Most people have been taught that alcohol increases the risk of accidents.

Smoking and driving can get you a DUI for an accident even in states where cannabis is legal. Current state laws for marijuana have focused on regulating it like alcohol while on the road. This is especially true when it comes to consuming and driving. Yet evidence of marijuana’s culpability in on-road accidents is difficult to prove.
Many states have reduced penalties for cannabis related crimes over the last few years. Yet as states continue to loosen regulations on marijuana safety, law enforcement is struggling to figure out how to establish a legal limit for drivers. They have focused on setting a blood-content test just like the .08 limit for alcohol.
A new study shows the challenges in accurately testing drivers.
One of the most difficult parts of testing is developing a threshold for what’s considered too high to drive. The conductors of the study concluded that “THC concentrations drop rapidly during the time required to collect a blood specimen in the U.S., generally within two to four hours.”
The low amount of time cannabis remains active for oral tests using the drivers’ saliva make it harder to fail than traditional tests. Saliva tests can be done roadside without a long wait but researchers found oral tests don’t provide “a precise measure of the level of impairment.”
Politicians are hesitant to implement concentration-based cannabis-driving legislation because it might ” unfairly target individuals not acutely intoxicated, because residual THC can be detected in blood for up to a month of sustained abstinence in chronic frequent smokers.” Depending on the direction that the new Attorney General Jeff Sessions takes the Justice Department over the coming years, detecting residual cannabinoids may be more important than registering intoxication.

Smoking weed is not safe while driving.

Cannabis intoxication has been shown to mildly impair a drivers psychomotor skills. It doesn’t appear to be severe or long lasting though. In driving simulator tests, this impairment was typically manifested by decreasing driving speed and needing more time to respond to emergency situations.
Yet this impairment does not appear to play a significant role in on-road traffic accidents. A review of seven different studies involving 7,934 drivers showed in 2002, “Crash culpability studies have failed to demonstrate that drivers with cannabinoids in the blood are significantly more likely than drug-free drivers to be culpable in road crashes.” And it’s not like people haven’t tried to prove a link either.
A Massive body of research exists that explores the impact of marijuana on psychomotor skills and actual driving performance. Researchers have done driving simulator studies, on-road performance studies, crash culpability studies, and reviews of the existing evidence. To date, the result of this research has shown how mildly cannabis affects driving abilities but that won’t stop the cops from hauling you off for having it in your system if you get in an accident.

Bad accidents

Marijuana has a measurable yet relatively mild effect on psychomotor skills.

Yet it does not appear to play a significant role in vehicle crashes, particularly when compared to alcohol. Researchers conducting a study for the National Institute on Drug Abuse said alcohol “significantly increased lane departures/minimum and maximum lateral acceleration”. Cannabis did not have the same correlation between consumption and decreased performance.

Researchers for the Highway Traffic Safety Administration funded study concluded Cannabis-influenced drivers are better able to measure their intoxication “may attempt to drive more cautiously to compensate for impairing effects, whereas alcohol-influenced drivers often underestimate their impairment and take more risk.”

People keep studying the link between cannabis, alcohol and car accidents.

The prevalence of both alcohol and cannabis use and the extreme morbidity associated with car crashes has lead to repeated research on the link between the two. According to another study, “drunk drivers are involved in 25% of motor vehicle fatalities, and many accidents involve drivers who test positive for cannabis.”
The researchers say that while both alcohol and cannabis impair performance in a “dose-related fashion” the “effects of cannabis vary more between individuals than they do with alcohol because of tolerance, differences in smoking technique, and different absorptions of Δ9-tetrahydrocannabinol (THC), the active ingredient in marijuana.”
The effects of a cannabis “high” vary according to dose but are more pronounced with highly automatic driving functions than with more complex tasks.” Basically making it easier to focus on a plan than instinctively react to something. With alcohol the opposite pattern of impairment is produced and people get distracted easier.

Cannabis and alcohol have a synergistic effect.

Because of an increased awareness that they are impaired, “marijuana smokers tend to compensate more effectively while driving than drunks” by utilizing a variety of strategies. Mixing marijuana with alcohol removes the ability to use such strategies as the two substances increase the potency of the other when mixed.
Cannabis and alcohol work on many of the same levels in the brain and both inherently affect chemical production in the brain. Mixing cannabis and booze will amplify the effects of both and can lead to serious repercussions. While studies have been inconclusive regarding whether cannabis use causes an increased risk of accidents; in contrast, unanimity exists that alcohol use increases the risk of crashes.
In addition, the risk from driving under the influence of alcohol and cannabis together is higher than the risk of driving under the influence of either alone. One study even recommends that patients who smoke cannabis wait several hours before driving, and avoid combining the two drugs.

Even schools have studied how dangerous driving while high is.

The first study to analyze the effects of cannabis on driving was conducted by Researchers at the University of Iowa’s National Advanced Driving Simulator, sponsored by National Highway Traffic Safety Administration, National Institute of Drug Abuse, and the Office of National Drug Control Policy.
The researchers found that cannabis use caused almost no impairment. The impairment that it did cause was similar to the change observed while under the influence of a legal alcohol limit. They basically couldn’t get cannabis to impair driving as much as one beer.
They tested impairment mainly with a simulator. “Once in the simulator—a 1996 Malibu sedan mounted in a 24-feet diameter dome—the drivers were assessed on weaving within the lane, how often the car left the lane, and the speed of the weaving. Drivers with only alcohol in their systems showed impairment in all three areas while those strictly under the influence of vaporized cannabis only demonstrated problems weaving within the lane.”

More research is needed to find the right limits.

All these study’s findings show that alcohol is a much more dangerous drug than cannabis yet regulated in a more relaxed manner. While driving while under the influence of cannabis can still get you locked up, it is unclear how dangerous it is. More research is needed to show exactly how much cannabis should be legally allowable but for the time being, driving after consuming any cannabis remains illegal.
Until the whole world switches over to autonomous vehicles and we don’t have to worry about driver error any more, people are still going to get into accidents (sober or not). It is best not to contribute to the problem and simply don’t drive while high. You never know when you might need to instinctually react to something in your lane. Thanks for reading.
