Cannabis exists in many varieties and sub-species. Cultivators and farmers have long been breeding different varieties with certain characteristics to create hybrids and specific strains.
Each cannabis strain has a different concentration of the cannabinoids tetrahydrocannabinol (THC), cannabidiol (CBD), as well as other compounds.
Producers grow the plants to have a certain look, taste, and effect on the user and brand them accordingly.
Currently, reports on the effects of different cannabis strains come predominantly from people’s experiences. Although researchers are studying the effects of a variety of cannabis strains on a range of medical conditions, there is still a long way to go in this area.
Keep reading to learn more about cannabis strains, and which are the most popular.
All strains of cannabis derive from the Cannabaceae family of plants. Some experts consider that Cannabis indica and Cannabis sativa are the
To create a strain, cultivators select a variety of traits to produce the effects they want. This is a similar process to how breeders create particular characteristics in dogs.
People often describe cannabis strains as being indica, sativa, or hybrid. Hybrid refers to a strain created by combining both indica and sativa strains.
Here are some
|Strain name||Plant species|
|Kush||Pure Cannabis indica or Cannabis indica hybrid|
|Afghan Kush, Hindu Kush, Green Kush, Purple Kush||Pure Cannabis indica|
|Blueberry Kush, Golden Jamaican Kush||Cannabis indica hybrid|
|Diesel Haze||Pure Cannabis sativa or Cannabis sativa hybrid|
Many producers crossbreed cannabis plants to develop new strains with specific characteristics. Experts suggest that there are over
One of the most important characteristics of a cannabis strain is the THC content. Some rules exist on naming each strain, but many producers do not name their products according to these rules.
Despite these classifications,
Experts suggest it is impossible to guess the composition of a cannabis plant by looking at its height, branching, or leaf appearance.
The only way to know the chemical composition of a cannabis-derived product is to analyze it in a biochemical assay.
So far, most
However, researchers and scientists remain unsure of the ideal quantities of THC and CBD that people should use for various medical conditions or recreation.
Although both THC and CBD are cannabinoids, they act differently in the body because they target different areas in the brain.
According to a
CBD, on the other hand, is non-intoxicating. Some people report mild physiological effects, such as reduced anxiety when using CBD.
Animal studies suggest CBD may help improve vomiting, nausea, pain, and offer neuroprotective effects on the brain.
However, since CBD can affect mood, some
The Food and Drug Administration (FDA)
- two synthetic THC medications for the treatment of anorexia associated with AIDS
- another synthetic cannabis-related product for the treatment of nausea and vomiting associated with cancer treatment
- cannabis-derived CBD for children 2 years and older who suffer from rare seizure disorders
The terms indica and sativa derive from the biolgical classification of these species, which is based on physical characteristics. Cannabis indica plants are shorter and have broad, dark green leaves. Cannabis sativa plants grow taller and develop thinner, pale green leaves.
In the past, people used these terms to differentiate the cannabis plants in terms of their effects and THC or CBD content. An article in
Previously, people believed that Cannabis indica plants contained higher levels of CBD. As a result, cultivators and dispensaries marketed indica-derived strains as a product that would lead to a more ‘relaxed high’.
Conversely, Cannabis sativa-derived strains that contained higher levels of THC would provide a more energetic high.
Many experts caution against this generalization, noting that even if this classification scheme were true, there is no way to be sure of the accuracy of any strain name.
There is no third-party agency that validates which strain names belong to indica, sativa, or hybrid.
To know exactly what is in a cannabis product, the manufacturers must analyze the product in a biochemical assay.
It is easy to see why this topic continues to cause debate. Cannabis is a complex plant, and, as of right now, there seems no obvious or simple way to categorize the various strains by ‘effect on the user.’
Each person who tries a strain of cannabis may have a different experience.
For example, some people describe the effects of Cannabis indica-derived products as sedating. However, other components of cannabis can also cause sedation, as well as other psychoactive effects. Compounds include:
These components are often absent in a description of a cannabis-derived product, which is why some experts suggest that manufacturers should abandon naming their products as sativa or indica. Using these names is misleading and far more complex than people once thought.
Although a naming system for cannabis strains exists, manufacturers do not always follow the rules. Some producers name the strain according to the smell of the plant or its lineage; others, according to the plant’s color.
A study in the
The following table lists the top 10 preferred cannabis strains among these participants:
|Strain name||THC (%)||CBD (%)|
|Lemon sour diesel||18.3%||0%|
|Master kush||25.6%||0 %|
|Sweet Skunk CBD||9.1 %||11.2%|
Depending on its effects, researchers noted that some participants preferred certain strains over others. For example, the
- Lemon sour diesel
- OG shark
For mental health conditions, such as anxiety and depression, the
- Jack Herer
- Island sweet skunk
- White widow
Please note that these examples of preferred cannabis strains come from user reports not from placebo-controlled clinical trials.
Two people using the same cannabis strain may have different experiences. To choose the best cannabis strain, people should speak with a healthcare provider who has clinical experience with cannabis.
Since cannabis is more readily available today than ever before, people need clear, accurate information on the effects of different cannabis strains for medical and recreational purposes.
Knowing the composition and physiological and mental effects of cannabis plants can help people and clinicians choose the most appropriate product.
Cannabis farmers crossbreed cannabis plants to create new strains that have different levels of THC, CBD, and many other physiologically active compounds.
Each plant may have different medicinal and recreational purposes. Researchers need to carry out further studies to better understand this complex plant and its effects on humans.
