What Cannabis Strain Has the Most THC, According to Lab Data?
The last several decades of cannabis breeding generated thousands upon thousands of strains, many with high levels of THC. This begs the question, “Which strain has the most THC?”
The answer, according to numbers pulled from Washington state’s I-502 data, might be Ghost OG. (Leafly filtered the data to remove suspicious outliers and avoid labs that may have inflated THC values.)
About Ghost OG
Ghost OG is a hybrid strain with a mysterious origin story likely written only on the ancient walls of an online growing forum. However, it’s said to be a cut of the original OG Kush passed along from one breeder, ORGNKID, to another named “Ghost.”
While its history is known by few, the name is known by many, preserved by a reputation built on numerous Cannabis Cup awards. Wearing a thick white sheet of crystal trichomes, Ghost OG can produce a predatory amount of resin best reserved for fearless cannabis heavyweights. Skillful gardeners can coerce loud aromas from this strain that reek of acrid lemon-pine cleaner and deep earthy goodness. Coveted Ghost OG genetics have been used to breed several other strain staples like Ghost Train Haze, Rare Dankness #1, and Banana Kush.
How Much THC Does Ghost OG Have?
Advances in cannabis lab testing have helped to put the terms like “strength” and “potency” in quantifiable terms—a percentage point that many consumers now primarily look to when choosing a strain. Though we now know that a strain’s subjective intensity is determined by a harmony of cannabinoids and terpenes, many people primarily focus on the THC content if looking for a powerful cannabis experience.
Through genetic selection and advancements in growing technology, cannabis plants can now produce over 25% THC by dry weight—a substantial increase from the single-digit figures strains touted in decades past.
Ghost OG’s average THC content, according to lab data, pushes past 28%, the highest figure in the dataset. Compare that to the average THC content of these popular strains:
- Blue Dream: 18.4% THC
- Girl Scout Cookies: 19.1% THC
- Sour Diesel: 18.5% THC
- GG #4: 21.4% THC
- OG Kush: 19.4% THC
- Granddaddy Purple: 17.5% THC
If cut from the original OG Kush mother stock, why is Ghost OG’s average THC percentage so much higher? Could it be that these prized Ghost genetics fell into the hands of particularly talented propagators and cultivators, while the potency score of the widely proliferated “generic” OG Kush was skewed by more lackluster samples?
