Hi there My family really needs some help our 75 year old grandmother was found unconscious hardly breathing and had a heart rate of 4 beats per minute pratically dead by the time ambulance workers arrived on scene well we get to the hospital and they begin working on her and are able to stablize her well the doctor comes out and yes she has high levels of crystal meth in her system well we all thought o bologna and we had her care flighted to another more high end hospital and again they come back with the same results now mind you think is a 75 yr old wome. Who can barley walk let alone leave her house to go out and score drugs so what I m asking is there one of her prescriptions that may have caused this false positive or what? We re at a huge lose here thanks
