Listing the cannabis strains with the highest THC levels is a difficult task, for one thing there are dozens of strains that yield high THC content. But the most important thing to keep in mind is that THC levels can vary quite a bit depending on environmental factors, grow conditions and the cultivators experience.
One strain may yield upwards of 30% THC from one grower, and the very same strain could yield only 20% THC from a different greenhouse.
THC Levels Higher Than Ever Before
Great genetics do go a long way though, certain strains are known for their high resin content, resiliency during growth and high THC or CBD levels. Hand picking the strains with the highest THC levels and selectively breeding them with complementary strains has given rise to a new age of marijuana.
Twenty, or even ten years ago, many of today’s popular strains didn’t exist. The cannabis strains of twenty years past didn’t pack nearly the same punch as their descendants. We can only imagine how potent marijuana could become in the near future.
Let’s focus on the present and take a look at some of the marijuana strains with the highest THC content.
20 Top THC Strains

Tutankhamun or King Tut ruled Egypt over 3000 years ago, he is now the namesake of one of the most potent marijuana strains on the planet. By potent we mean it contains quite a bit of tetrahydrocannabinol (THC), the psychoactive component of the cannabis plant.
