I Have Two Grandsons With Asthma, One Aged 4 And

I have two grandsons with asthma, one aged 4 and one aged 6. They regularly us a ventolin inhaler when they have attacks and to prevent an attack when they have a bag cold. I am concerned to learn there is a risk of developing depression as a result of long term use. And I am particularly concerned about its long term historical effect on teenage males.
