Early Sex, Drugs More Common Among Teens With Half-Siblings, Study Suggests
SUNDAY, Aug. 11 (HealthDay News) -- Teens who have half-siblings -- brothers or sisters with a different father -- are more likely to use drugs and have sex by age 15 than teens with only full siblings, according to a new study.
