The Bismarck Police Department is investigating a case where a newborn baby tested positive for cannabis, the chemical found in marijuana. Lt. Dan Donlin said Burleigh County Social Services contacted police after a doctor at Medcenter One filled out a form 990, which is a report of suspected child abuse. The police report stated that a doctor tested the baby for cannabis after seeing symptoms of drugs in the baby's system. Donlin would not release the names of the child or the parents because he said the case is under investigation. [end]
