Never doubt a dedicated junkie’s ability to score dope. They may not have money to pay rent, eat food or ride the bus, but by God, they’ll find a way to shoot drugs in their veins. Pittsburgh police say Karen Remsing of Vancouver showcased this creative tenacity when she came to Steeltown to visit her terminally ill 15-year-old son in the hospital, only to unhook his intravenous drug tube, siphon out some sedative, then inject herself with it in an act that sounds like a deleted scene from the movie “Trainspotting.” The Pittsburgh station WPXI reports that the woman’s husband of 22 years, who was also at the hospital, defended his wife, telling the station off-camera that the cops “got it wrong.”Her son was in the hospital for surgery involving his small intestine. The drug she allegedly was so keen on scoring from her son was Versed, a type of benzodiazepine that’s used to sedate patients and induce amnesia before surgery. Indeed, when hospital staff found the woman, she was slumped over a couch in her son’s room in a state that would have left her half way ready for the operating room. Hospital staff say they found needles in the trashcan and blood on Remsing’s clothes, though the woman said the needles weren’t hers and the blood was from cutting her fingernails. And if stealing her kid’s medicine wasn’t enough, Remsing apparently tried to hook the IV tube back up to her son after she was done with it, and in the process, formed an air bubble in the tube that could have killed him.The 42-year-old woman was charged with child endangerment, reckless endangerment, theft, criminal mischief and possession of prescription medication without a prescription.In other news, Scottish heroin addict Mark Renton, seen below, says he totally understands where Remsing was going with this.
