in the ER kids come in all the time with their heart racing from pot--especially when they were put out the scare in the 70's of spraying crops! Seems it might be more age related. Plus, why was this guy on Vicodin and MMJ; perhaps his original condition caused a lot of this. A heart rate 120 isn't too bad for a kid with "problems!" The ER never calls the cops, unless you bring a lot of the stuff in with you and then, the doc might want to keep it! we r 2 busy to worry about a legal user! A racing heart is a concern, if u don't know the cause! Heck, u can hold your breathe and put your face in ice water too--but then the ER doesn't get the fee! Whatever is going on mentally can effect anyone physically and ER's don't have shrinks in them! My heart gets to 120 every time I back up into something in my car!
