Question Related to Coughing So I vape weed from my dry herb vape pretty much daily and I've developped a cough. I'll cough a few times during the day but the real problem is at night when I'm in bed. 

I have friends that smoke multiple bowls daily that do not have any cough and I'm just wondering if I am doing something wrong at a basic level or if there is something I can do to prevent that? 

Are there any vitamins or supplements I can take to fight the cough... or do I just have weak lungs and have to live with it?
