MALE TWINS WHO SMOKE MARIJUANA show no significant health or socio-demographic differences than their non-using siblings, according to the findings of a recent study published in the medical journal Addiction. Authors reported, "No significant differences were found between the former marijuana user twins and their siblings for current socio-demographic characteristics; current nicotine or alcohol use; lifetime nicotine or alcohol/dependence; past 5-year out-patient or hospitalizations; or health-related quality of life." They concluded, "Previous heavy marijuana use ... does not appear to be associated with adverse socio-demographic, physical or mental adverse health effects."
