Key Terpenes for Focus
Terpenes are aromatic compounds that contribute to a strain's effect. For focus, look for pinene, which is associated with alertness and memory. Limonene may support a positive mood. Terpinolene appears in many energetic strains. Myrcene, on the other hand, tends to be sedating and is less helpful for focus.
