As the intensive selective breeding of cannabis progresses, breeders are producing specimens with sky-high levels of THC never before seen in nature or the grow room. Demand for such high levels of the psychoactive cannabinoid has risen as smokers become more tolerant to its effects and consequently seek out more intense highs. These powerful and innovative strains provide a high that comes on instantly, is long-lasting, and catapults the user into an intense psychoactive experience. They are also of great value to medical cannabis users who require high levels of THC.
