Its always made me cough unless I temp step slightly, vape off the lower temps first, get the thc out the way. If I start at a high temp (especially with the volcano or daisy that i had), i will cough and cough and cough and cough.
Ive found dabbing at low temps is best as I can get the same amount of hit with way less vapour. Ive also finally found two vapes that DONT make me cough very much even if I start at high temps : the Ti vapcap, and Pipes Project atomizer. And both thru water is a real dream.
My lungs are finally not having breathing problems in the morning. Coughing so much less than I used to. Although with the volcano, I had great results with a cotton filter making hits smoother. But it was still too much faff.
EDIT: I've also found that a lot of my coughing is due to my lungs getting irritated and then starting to cough, causing more coughing. A lot of times if I power through that urge to cough, it passes. I still then get a delayed little cough, maybe clearing a little mucus but it means my lungs dont enter coughing spasm mode. This has been a great help in not letting a cough turn into an asthma attack.
