The duration, amount, and frequency of exposure to terpenes at concentrated dosages (those terpenes which have been concentrated outside of their normal whole-plant product form) will be an important factor in the potential adverse effects of exposure to those concentrated dosages. If you are experiencing headaches while using a concentrated product with high concentrations of limonene/pinene, consider reducing your intake of the product, increasing your ventilation and/or stopping use until you are symptom-free.
