How this page is ranked
1Rankings combine DeePuff strain fields, effect/medical-use tags, terpene signals, potency, rating, and review depth depending on the page intent.
2Numbers are transparent records, not guarantees: cannabinoids and terpenes shift by breeder, phenotype, grow, harvest, storage, and lab method.
3Medical or wellness framing is treated as user-reported discovery guidance and should not replace professional advice.

Frequently Asked Questions
What is the highest THC strain?
Strains like Godfather OG, Grease Monkey, and Bruce Banner have been tested at 30%+ THC. However, actual potency varies by grower and batch.
Is higher THC better?
Not necessarily. The entourage effect means terpenes and other cannabinoids play a major role in the experience. A 20% THC strain with a rich terpene profile can feel stronger than a 30% strain without one.
