Three markers: pinene-dominant terpene profile (> 0.3%), sativa or balanced hybrid genetics, low-to-moderate THC (15-20%). Pinene may counteract some short-term memory impairment associated with THC — useful when the session has to hold up under cognitive load.
Names that signal focus-supportive profiles: Jack Herer (sativa), Blue Dream (balanced hybrid), Strawberry Cough (sativa), Cinex (sativa), Romulan. Aroma: pine, rosemary, herbal. Look for these names or ask budtender to filter by pinene.
For sustained focus: 2.5mg edible produces a noticeable but functional lift that fades over 3-4 hours. 5mg is the upper limit for most shoppers who want to stay sharp. Above that, cognitive load increases.
