The strains with the highest THC levels, the psychoactive component of cannabis.

THC, acronym for TetraHydroCannabinol, is the primary cannabinoid responsible for the effects of cannabis. It is secreted by resin glands known as trichomes, and its concentration directly influences the psychoactive properties of both cannabis herb and resin.

Therapeutic use of THC

In addition to its psychotropic effects, THC has therapeutic properties that make it valuable in treating various conditions. Its benefits have led to the official recognition of cannabis and its derivatives as medicine in many countries, including the US and Canada.

Cannabis is used by many patients for its positive effects in treating a wide range of diseases and symptoms, such as:

  • Tourette's Syndrome (reduction of spasms)
  • Alleviating nausea and vomiting
  • Stimulating appetite
  • Pain relief (especially for chronic and neuropathic pain)

Here, we offer a selection of regular and feminised strains with THC levels exceeding 25%, classifying them as highly potent. To put this in perspective, the average THC level in many strains today is around 15-20%, which is already considered THC-rich.

While THC acts in synergy with other cannabinoids like CBD or THCV, as well as terpenes, a high THC concentration remains a strong indicator of a strain's potency.

High THC level, maximum potency

Some of the most potent strains include Gorilla Glue, which can reach a THC level up to 30%, Y Griega up to 27%, or Blisful Wizzard, which can reach an astounding THC level up to 34%.

You can find the most TetraHydroCannabinol-rich strains in our catalogue here. Enjoy them!
