• Hallucinogen Rating Scale

    Beginning on the next page is a list of statements referring to the effects of the drug you received. For each statement, please mark the answer that corresponds to the most intensely you experiences that effect during the time period specified. Please mark only one answer for each item; mark the one that seems best, even if none matches your experience exactly. For example, "Visual Effects," if you experienced extremely intense visual effects during the time period, mark "Extreme." Do not worry if your answers to some questions are opposite to others.
