We read focus broadly: mental clarity, alertness, attention, memory, learning and work performance. Nine terpenes add to the score, with 1,8-cineole and α-pinene out front. We actively pull strongly sedating profiles down so only daytime-friendly matches surface here.
Which terpenes matter
Nine terpenes add to the focus score: 1,8-cineole (3.0) as the best-backed focus terpene, from a human study on plasma cineole and cognitive performance, α-pinene (2.7) as the canonical wakefulness terpene with acetylcholinesterase inhibition, limonene and geraniol (1.8 each) for alertness and mental freshness, and β-caryophyllene, β-pinene, fenchol, α-terpineol and α-bisabolol (between 0.8 and 0.9) as smaller contributions.
Antagonist damping caps the focus score of sedating strains: anything that scores high for sleep reaches at most forty percent of its unrestricted value in focus. That keeps β-myrcene dominant profiles out of the focus listing, even when they bring along individual focus terpenes. Through soft assignment, generalist terpenes spread their score budget across all effects, so strains with a clear profile emphasis rank higher than broadly built hybrids.
The 1-to-10 values shown are calibrated per effect against the real distribution. That puts the top strain for focus visually on a par with the top strain for inflammation, even though the absolute focus values in the database sit lower. Method details: Methodology.

Common questions
Which cannabis strains don't make you drowsy during the day?
Strains with a pinene, limonene or cineole share above the detection threshold and a low β-myrcene value. Often these are limonene-pinene dominant hybrid profiles or chemovars with measurable 1,8-cineole. In the focus filter we actively pull sedating strains down.
Which terpenes count for focus?
Nine terpenes add to the focus score: 1,8-cineole with the highest score from a human study on cognition, α-pinene as the canonical wakefulness terpene with acetylcholinesterase inhibition, limonene for alertness and mood clarity, geraniol for mental freshness, plus β-pinene, fenchol, α-terpineol, α-bisabolol and β-caryophyllene each with smaller contributions.
How do you keep strongly sedating strains from showing up under focus?
We actively dampen sleep strains in the focus score. Sleep and focus are pharmacologically incompatible. A strain that scores high for sleep reaches at most forty percent of its unrestricted value in the focus score. That keeps sleep strains from ranking in parallel under focus, even when they nominally carry individual focus terpenes.
Does a high THC content automatically make you more awake?
No. THC is primarily psychoactive, not activating. What gets experienced as alertness comes down to the terpene profile. A 30% THC strain dominated by β-myrcene feels more sedating than a 22% THC strain with a pinene or cineole profile. Our focus sorting runs purely on terpenes; the THC content is shown separately as a filter.
