Happiness Measure Statistics Elaboration / Remarks M-FH-c-sq-v-3-b OR = - T2 happiness (age 21) by onset of earlier use of canabis

Odd Ratios denote chance of being Unhappy. Sign of correlation reversed to fit standard notation in WDH
M-FH-c-sq-v-3-b OR = - p < .05 T2 Happy (vs Very happy) OR unadjusted
- age 15 or less OR = 1.97 CI95[1.30-2.98]
- age 16-17      OR = 1.63 CI95[1.20-2,21]
- age 18 or more OR = 1.58 CI95[1.08-2.32]
M-FH-c-sq-v-3-b OR = - p < .05 T2 UNhappy (vs Very happy) OR unadjusted
- age 15 or less OR = 2.81 CI95[1.45-3.44]
- age 16-17      OR = 2.33 CI95[1.40-3,88]
