My husband smoked meth for 5 years, he quit 18 years ago, only to replaced it with alcohol. After drinking up to a bottle of bourbon a day (sometimes more) he almost died in May of 2017.  Now, he experiencing severe lung problems. I am trying to do as much research as possible..  It’s known that long term alcohol abuse can cause lung diseases, but I’m wondering if the meth is playing a part in it too... 

  Could anyone help me with this??
