I have noticed my 16 year old daugther using her inhaler, that is only supposed to be used before exercise, at times when I am certain that she does not need it. Should I be concerned? She supposedly has exercise induced asthma although I dont believe this was properly tested for diagnosis. Is this something she could be using to get a high off of? Can it be a cause for the phone calls I have been getting about her being sick at school, headaches, nausia, vomiting?
