The Weirdest Cannabis Strains: What Effects Do They Make?

Cannabis strains come in all shapes and sizes and with a range of purported effects. Some strains are known for making users feel energetic and creative, while others are known for inducing a sense of relaxation and calm. These strains have been selectively bred for centuries to achieve certain desired effects. 

However, there are a few strange cannabis strains that don’t fit into any traditional categories. These strains can be unpredictable and often produce unusual and unpredictable effects.

In this article, we’ll take a look at some of the weirdest cannabis strains available and explore their effects on the human mind and body. These strains, although popular, aren’t readily available in the market due to how rare they are, and you may have to dig deeper for some of them. As for those looking simply to try something new in this space, you can choose one of the best cannabis seeds on TheSeedFair website.

Dr. Grinspoon: Cannabis or Berries?

The Dr. Grinspoon Sativa strain is courtesy of Dr. Lester Grinspoon, a Harvard professor who was a strong advocate for the legalization of cannabis. 

What sets Dr. Grinspoon apart from other cannabis strains is its appearance. In contrast to other strains that develop dense buds at the nodes of the branches, the calyxes in Dr. Grinspoon are almost entirely separated from each other. 

As a result, the plant produces small floral clusters with a purplish hue that spread across the entire plant, giving it an appearance of a berry vine. This unusual morphology may be linked to the plant’s high levels of cannabidiol (CBD), which is known for its therapeutic effects.


It is one of the most popular strains on the market, and for a good reason — it delivers an intense cerebral high that is perfect for daytime use. The THC content of this strain can reach up to 25%, making it one of the most potent strains available. 

Dr. Grinspoon is a favorite among many cannabis enthusiasts for its unique floral scent and uplifting, long-lasting effects. Some people also find that it helps them focus on tasks and stay motivated.

Frisian Duck: The Plant With the Perfect Disguise

Developed by the Dutch Passion seed bank in Amsterdam, the Frisian Duck is a cross between the strains Frisian Dew and Ducksfoot. 

This unique cross retains the leaf pattern of the Ducksfoot strain but leaves its parent behind in the beauty contest by producing lovely buds that burst with deep purple tones. These are tiny buds that boom with floral notes of pine and the tangy scent of citrus. 

Taking onto the property of Frisian Dew, it thrives well in harsh outdoor growing conditions and is a high-yielding variety of cannabis. 

Frisian Duck is a cannabis knight in disguise. The webbed leaves of this plant, covered in purple flowers, do not look anything like the regular cannabis leaves, making it easy for people to mistake them for a wild flowering plant species. This is a great advantage for growers who want to keep their cannabis growing operation secret.


The effects of the Frisian Duck strain are quite mood-elevating. They provide a sense of well-being and calm without the intense euphoria associated with other strains of cannabis. This makes them ideal for daytime use when you need to remain clearheaded and productive. 

The high CBD content of both parents is also passed on to the offspring, making it a great choice for medical cannabis patients. 

Black Haze: A Gothic Cannabis Strain

Black Haze is a new, ultra-potent cannabis strain that produces near-black buds. This gothic strain is a cross of three different strains: Sir Jack, Skunk Auto, and Pakistani Chitral Kush. 

The flavor profile of Black Haze is marked by woody notes and topped with flavorful notes of berries and cherries. It’s quickly gaining a following among cannabis enthusiasts for its intense psychoactive effects. 


Black Haze induces a mellow, relaxing high that lifts your spirits and helps your mind and body relax without being too overpowering. You will feel at ease and comfortable, making it the perfect choice for social occasions or when you need to unwind after a long day. 

ABC: Australian Bastard Cannabis

ABC, or Australian Bastard Cannabis, is another strain that has made it into our weirdest cannabis list, partly because of its name and primarily because of its distinctive morphology. If there’s any strain that’s most unlike a typical cannabis plant, it’s this one.  

Australian Bastard Cannabis, as the name suggests, is native to Australia. It’s another cannabis plant that disguises itself almost perfectly. The leaves of the plant have small, lustrous, smooth-edged lobes that have an irregular shape and size. The leaflets are not serrated like those of traditional cannabis plants. 

The strain’s thin branches and compact size enable it to withstand even the strongest winds. The plant is known to thrive in the harshest weather conditions on the shores of Australia and shows high resistance to diseases. 


Like every good thing has its drawbacks, so does the ABC strain. This high-yielding variety is low in THC levels and far less potent compared to other strains on the market today. 

Therefore, its effects on the mind and body are pretty mild, and users do not experience a strong high after consuming this strain. 

Polyploid Cannabis: The Strain With Abnormal Chromosomes

The normal cannabis plant has two sets of chromosomes in a cell. However, some cannabis plants are polyploid, meaning they have more than two sets of chromosomes. Polyploid plants are generally larger and more robust than their diploid counterparts.

The benefits of polyploidy in cannabis are not yet fully understood, but preliminary research suggests that it may confer some advantages to the plant. For example, polyploidy may make the plant more resistant to pests and diseases. 

Additionally, polyploid cannabis plants may produce higher yields and have a higher THC content than diploid plants.


When consumed, polyploid cannabis strains can produce powerful effects. Some users report feeling euphoric and happy, while others experience deep body relaxation. 

The high from polyploid strains can last for several hours, making them an excellent choice for those looking for a long-lasting buzz.
