Frequently Asked Questions

Which are the strongest, Indica strains or Sativa strains?

The distinction between Sativa and Indica doesn’t significantly impact the strength. In other words, neither type is inherently more potent than the other. The potency primarily hinges on breeding and THC levels. The world’s most potent marijuana strain leans towards Indica in its hybrid composition. It’s entirely possible that a Sativa hybrid could claim that title in the future.

What makes cannabis strains potent?

In 2020, a study conducted by UC Boulder examined the purported potency of THC in 121 regular cannabis users. Those who opted for smoking cannabis flower were given a choice between 16% or 24% THC flower, while participants using concentrates could select from options containing 70% or 90% THC. The researchers measured THC levels in their bloodstream at three specific time points: before consumption, immediately after, and an hour after.

As anticipated, participants who chose concentrates showed higher THC levels, especially those using a 90% extract. However, surprisingly, the reported sensations of intoxication were similar among all users.

It’s important to note that THC levels alone do not solely determine the strength of a cannabis product. Various factors, including terpenes, CBD, and other components, play a significant role in shaping the type of high a cannabis user may encounter.

What THC percentage is considered highly potent?

Determining what constitutes a high THC percentage can be subjective. For instance, a strain with 10% THC may have a more profound effect on you than one with 15% THC. It depends on how your endocannabinoid system reacts to the compounds in the strain.

There’s a general guideline when evaluating THC percentages. If it exceeds 15% THC, it falls into the average THC category. Strains with 20% to 25% THC fall firmly into the high category, and first-time cannabis consumers must take precautions.

What is the record for the highest THC percentage ever documented?

Over the past few decades, various strains have claimed the title of the highest THC strain. Godfather OG surpasses all other varieties with an astonishing 35% THC content.

What is the advantage of consuming the strongest marijuana strains?

Utilizing the most potent cannabis strains isn’t solely about achieving a strong high; for many, high-potency strains offer a range of benefits.
