Ok so i have the extreme q and the solo arizer and I still sometimes cough from both of them... I heard hot water is good but I also heard ice water is good, and then going through water filtration (the vapexhale cloud seems awesome) but I can't afford the vapexhale.... what would be the best method so I dont cough? I would love some advice from people with bad lungs or asthma. Thanks!!! sincerely, a hurting stoner.
