From: Impaired vision in children prenatally exposed to methadone: an observational cohort study

Left, by drug exposure group: 1) opioids alone (n = 17); 2) opioids + cannabinoid (n = 12); 3) opioids + benzodiazepine (n = 14); 4) opioids + benzodiazepine + cannabis (n = 30); 5) opioids + stimulants (cocaine and/or amphetamines) ± benzodiazepine or cannabis (n = 25). Right, by neonatal abstinence/opioid withdrawal syndrome (NAS/NOWS) treatment category (n = 47 treated, n = 51 not treated).
