This is represented using SUSTTPT, SUSTRTPT, SUENTPT and SUENRTPT. SUPRESP is used to indicate that the use of cigarettes was solicited on the CRF. | | Row 2: | Shows the subject uses marijuana starting in 2002 and stopped using it on the day of the baseline visit. SUPRESP is used to indicate that the use of marijuana was solicited on the CRF. | | Row 3: | Subject 1234006 is a former smoker. The date this subject began smoking is unknown, but it was sometime before the assessment date; this is shown by the values of SUSTTPT and SUSTRTPT. The end date of smoking was collected, so SUENTPT and SUENRTPT are not populated. Instead, the end date is in SUENDTC. | | Row 4: | Shows the subjects had missing data for the usage of recreational products; this is indicated by SUSTAT = "NOT DONE". The reason is in SUREASND. |
