5 Best High THC Strains in Canada to Blow Your Mind

high thc

High-THC strains have become hugely popular in Canada. Cannabis strains with higher THC percentages aim to deliver potent therapeutic and mind-altering effects when consumed.  The most potent cannabis strains, such as Godfather OG, are known for their remarkable THC levels and intense effects.

Today’s high THC strains are not the same buds you would have found decades ago. In the 1980s, cannabis flower had an average tetrahydrocannabinol content of about 4%. Nowadays, it is not uncommon to find strains with levels reaching more than 25%. 

If you’re a new cannabis user, you may be asking "What does high THC mean?" or "Where can I buy the best high THC strains in Canada?". We're here to guide you through these questions and help you find the most potent strain in Canada! 

What Does High THC Mean in Canada?

Tetrahydrocannabinol (AKA THC) is the primary psychoactive compound in most cannabis strains. It is responsible for the characteristic "high" you feel after consuming marijuana.

Strong weed strains are cannabis strains that contain more than 10mg or 25% THC per serving. The tetrahydrocannabinol content in cannabis products is an important factor to consider when determining a product's strength or potency.

With that said, there is a wide range of high-potency cannabis products. Some of them flaunt THC levels of 95% or more. These variants are known as “Cannabis Concentrates” and their popularity has soared in recent years.

Does THC Percentage Matter?

Does the THC percentage matter? Sometimes!

If you're looking to buy the strongest weed strains, choosing a higher THC percentage may seem like a no-brainer, but it doesn't paint a complete picture. It is a common misconception that cannabis strains with a higher percentage will always be high-quality buds, and therefore result in a stronger and faster high.

It is essential to realize that finding a high THC strain in Canada does not always equate to it being a high-quality product. While the warm climate of certain regions is ideal for growing, it is challenging to verify the exact THC percentage of each harvest. As each plant is organically natural, THC percentage will vary slightly with each harvest. 

The final product quality will depend on several factors, not limited to:

  • Growing techniques 
  • Cultivation techniques
  • Harvesting process
  • Curing techniques
  • Extraction method
  • Packaging
  • Humidity levels and storage environment
  • Aromatic compounds present in flower

Above all, several studies prove the fact that THC percentage does not accurately track intoxication levels. While it is difficult to confirm THC test results at home, research in 2020 found that ingesting potent weed strains (with more than 24% THC content) had comparable effects to consuming cannabis strains with 16% tetrahydrocannabinol.

What is the Highest THC Strain?

The highest THC strains are typically found with THC levels ranging from 25% to over 30%. New strains with percentages in this range are usually indica strains or indica heavy varieties that are bred for pure potency. Due to their strength, they are best suited for seasoned stoners or those seeking powerful relief. 

What is the Most Potent Form of THC in Canada?

Delta-9 tetrahydrocannabinol is considered the most high-potency form of THC in Canada. It is the main psychoactive compound found in cannabis, responsible for producing intense, high feelings. This chemical works by binding to different receptors in the human brain that are involved in the regulation of memory and mood.

While some people use Delta 9 for recreational purposes, it can also used for its medical benefits, like appetite stimulation and pain management. While there are different forms available in Canada, such as Delta 8 and Delta 10, Delta 9 THC is more widely studied in the cannabis community.

It is important to note that high potency does not always indicate high quality. Other cannabinoids and terpenes also play a significant role in describing the quality, taste, and experience of weed strains.

What are the Effects of Using High THC Strains?

High-THC weed strains in Canada are not without potential side effects. While these vary from mild symptoms, such as the munchies to more severe, such as increased heart rate and impaired cognitive function, we recommend exercising caution to avoid a bad trip. Even a few small puffs of one of the strongest strains could result in a rapid and intense body high, or worse a negative cerebral experience. 

Start your cannabis journey with low-potency flower and gradually experiment with stronger weed strains.  This is especially important if you’re an inexperienced user or someone with low tolerance. When trying potent marijuana strains, it is crucial to start with low doses to ensure a safe experience.

Benefits of Using Strong Weed Strains

Although more peer-reviewed studies are needed, up-and-coming research supports the statement that strong weed strains are safe to consume. Some medical research facilities believe these powerful strains could have legitimate use in medicine due to their positive effect on patients' moods and medical symptoms.  

Let’s see what industry experts have to say about the potential effects of using the highest THC strains:

1. Pain Management

The best potent weed strains have been shown to help reduce chronic pain by changing the pain perception pathways in your brain. Many users find these strains provide relief from conditions such as:

  • Migraines
  • Endometriosis
  • Fibromyalgia
  • Arthritis

In some instances, potent weed strains can help replace the long-term use of non-steroidal anti-inflammatory drugs, such as ibuprofen.

2. Neurological Disorders

Cannabis with higher THC percentages may affect the limbic system (a significant system of the human brain that controls emotions). As such, healthcare professionals have experimented with new cannabis strains to treat the following health conditions:

  • Post-traumatic stress disorder (PTSD)
  • Multiple sclerosis
  • Epilepsy
  • Anxiety

3. Reduce Inflammation

One of the desired effects that therapeutic stoners seek is inflammation reduction. Inflammatory conditions cause symptoms that can range from mild to debilitating for the patient, and more people prefer strains over prescription medication.

The most potent cannabis strains are used by cannabis consumers to help relieve inflammatory conditions, such as:

  • Rheumatoid arthritis
  • Irritable bowel syndrome (IBS)
  • Crohn’s disease

There is potential that ingesting high-THC edibles and weed strains under a treatment plan can improve your overall health by reducing inflammation.

4. Improve Sleep Quality

High THC strains in Canada aim to deliver relaxing effects to the user. Strong weed often has mind altering effects on it's consumer, which in turn can relieve stress and improve sleep quality.

Your healthcare professional may suggest a specific dose or THC percentage to treat sleep disorders, such as insomnia. While there are many options available on the market today for sleep aid, certain strains, such as sativa strains, have energizing effects and should be avoided in the evening.

For easy cannabis use, we recommend dosing with edible gummies or cannabis vapes. They are a discreet way to dose as much THC as you need before bed-time.

Risks of Overusing a Potent Strain

Though potent THC weed strains have significant therapeutic and psychoactive effects, there are some health risks associated with misusing these substances. When using potent marijuana strains, it is important to start with low dosages to ensure a safe experience, particularly for those who are new to cannabis or trying a new strain.

The following adverse side effects may be experienced if the user consumes too high of a dose:

  • Difficulty sleeping
  • Intense hunger
  • Mood swings or irritability
  • Poor coordination
  • Rapid heartbeat
  • Disturbed or confused thoughts
  • Difficulty concentrating
  • Paranoia

To avoid these health issues, be sure to consume the right dosage of THC. Start with a small dose and allow your body to adjust to the changes.
