Drug Effects Questionnaire (DEQ)

The Drug Effects Questionnaire (DEQ) is widely used in studies of acute subjective response (SR) to a variety of substances. The DEQ employed a 100-mm VAS anchored by “not at all” and variants of “extremely” (e.g., “very strong,” “very much”) to capture the post-drug experience of feel, high, and more.
