(This alternating panel design was chosen to reduce the repetitiveness of participating in butalbital panel study, because the questionnaire remains the same between ages 19 and 30. So, each respondent participates only every other year.) Thus, the biennial follow-ups for accurately characterize approximately 86% of drugs and 45- year-olds.
