ADDERALL? University Exams Produce a Distinct Chemical Signature in Sewage, Study Suggests.

Actually, no: “Other substances, including ADHD medications, showed no significant exam-related increases, while markers associated with caffeine consumption and artificial sweeteners actually appeared to decline relative to the general community, which might seem a bit surprising during a busy exam period.”

But: “”The consistent direction of change across multiple antidepressants and metabolites suggests a possible examination-period increase in antidepressant consumption within the university campus, although the evidence remains suggestive rather than conclusive.”

Plus: “Alcohol consumption, less surprisingly, also appeared to be temporarily suppressed during exam time, with wastewater measurements suggesting a rebound after the exams concluded.”
