After patients are screened and consented, the following variables will be collected at baseline, with some being collected as part of the standard YouScript requisition form: demographics, current smoking status, active medical conditions, liver or kidney dysfunction, drugs of interest and other concomitant medications (including date of initiation of therapy, dose, frequency, and indication, respectively), previous ADEs to any drug of interest, and buccal swab/blood sample for YouScript testing. The site will not be required to enter data collected on the YouScript requisition form into the eCRF.
