Historical documents from around the world suggest that we have been using marijuana for as long as four thousand years.

Over that time, there have been a lot of strains with a lot of crazy names. It makes you wonder, where did it all begin? What was the original or OG strain of weed?

A good start is understanding common words like Kush, Landraces, Sativa, and Indica. A name commonly given by growers to original strains (non-hybrids) is landraces.

These are wild, natural strains of marijuana that come from a certain region or territory. For example, Afghan Kush is a landrace strain from specific regions of Afghanistan.

However, no one really knows if there is a single original strain of weed. Did any specific strain come before another? That’s hard to tell.

There’s a collection of the oldest weed strains currently known.

Many original marijuana strains were discovered thousands of years ago but given specific scientific names in the 18th century.

Cannabis Sativa is probably the first weed strain given a scientific name.

Cannabis Sativa is one of the landrace types of cannabis. It originated in Asia and Northern Africa, but it didn’t take very long for it to find its way to the west.

Cannabis Sativa grows better on the equator than it does at extreme latitudes and grows taller than most other landraces. However, there are different types of Cannabis Sativa that popped up and originated in different parts of the world.

They are landraces, too. Some of them include Acapulco Gold, originating in Mexico, and Panama Red, originating in Central America.

These are all original strains of weed belonging to the Cannabis Sativa group of landraces. It seems marijuana didn’t have a single original home from the beginning of time. Different strains can survive in different conditions, and overall the cannabis plant is quite adaptable.

Cannabis Indica is another type of landrace. This is where we get famous original cannabis strains like Kushes, such as Afghan Kush and Hindu Kush.

Cannabis Indica can be traced back to the mountains of Afghanistan, Pakistan, and India, to a mountain range that borders those three countries, the Kush Mountains.

Cannabis Indica didn’t really make its way to Europe freely until the 80s; it’s always been much more prevalent in Asia.

This original strain of cannabis is shorter than Cannabis Sativa and is well adapted to growing mildly north of the equator. Cannabis Indica has been used and bred to create some of the most popular hybrids we smoke today.

Both the famous Afghan Kush and the Hindu Kush originated in the Kush Mountains of Afghanistan. However, other landraces, such as Northern Lights and Blueberry Kush, exist. These are all landraces, and it’s hard to tell which one came around first.

This is the strangest one of the original cannabis landraces. It’s been spotted growing wildly around the world from Eastern Europe, the Himalayas, and Siberia.

This plant is the smallest one of them all and grows very well in northern climates, which can be very harsh and almost freezing at times.

It is not an overall high potency landrace and isn’t often used as a landrace anymore. It is only ever grown to use as a hybrid with another strain. This particular strain is primarily used for industrial hemp. Popular hybrids that use this are Gorilla Gold and Low Ryder.

Well, if you’re going by how old the name is, Cannabis Sativa takes the cake.

But does that necessarily mean it was the oldest? Weed is a persistent plant and grows under just about any climate all over the world. As a result, there are non-hybrid, natural species of marijuana that just found themselves on the face of planet Earth.

These are all original strains of weed, and a lot of them are available for purchase for you to try. They are not mixed with any other strain of weed and were found growing naturally in their habitats. And just how old are they? Research says about four thousand years old.
