increased likelihood of rVUS in women who reported cannabis use during adolescence

excess of rVUS in the twin using cannabis at an early age ... can be attributed to factors unique to adolescent cannabis use that may have causal characteristics

adolescent onset cannabis-using twin member was at two times increased odds of reporting rVUS relative to their never or later‑onset user co‑twin

elevated odds of rVUS in adolescent cannabis users persisted ... women who use cannabis prior to age 17 are more likely to report rVUS

the exposed (i.e. adolescent onset) twin was at consistently greater likelihood of reporting rVUS

elevation in the likelihood of rVUS in the adolescent-onset twin relative to their genetically identical never/later-onset user co-twin (OR 2.25, 95% CI [1.14-4.44])
