@norlin: great question. they do, but not nearly as much, maybe 1/5th the strength of the wheezing/rattling/coughing I get from vaping herb. I was a diehard omicron user for a while, had the v1 and v2 and used them exclusively for about 5 months vaping nothing but oils and waxes. i didn't have so much a problem back then, just the occassional wheeze and cough, but not nearly as strong/often. It was bearable. I did elect to leave the exclusive omicron domain though, as I really missed the freshness and flavor of flowers, and the omicron made my breath stink like HELL for some reason. Dried out my mouth, and I swear I could taste the metallic nychrome wire in my mouth. After finding out the carts and wires were made in china, I looked into a thermovape dart LV, then eventually went back to vaping flowers only.
UPDATE:
So I'm not sure which was responsible for the success, but I saw some *limited* success/progress last night trying the tips out I've seen in this thread. I triple layered the screens to cut down on particulates getting through, but the biggest "combo breaker" for me, was taking a 2nd shower midday.
The dry lung theory seems to be on to something. I theorized that the reason I only coughed at night, and not in the mornings, was possibly because the hot steam in the shower hydrated my lungs a bit. So, I took a few extra sessions, made sure I got that wheezing/rattling sensation in my chest just a little bit, then I hopped in the shower at 8pm and took a 15 minute *hot* shower, breathing deeply the whole time. I popped out, rattling/wheezing sensation is gone. I coughed up quite a bit of mucus in the shower, so I'm guessing the liquid water condensing in my lungs unsticks them, and gets me to cough up particulates and irritants via mucus.
I vaped again, then went to bed. I woke up this morning with a *very* slight rattling/wheezing, but it went away about 5 minutes after I woke up (compared to an hour, hour and a half of hacking and wheezing in the morning).
@luchiano/venemous: I'm going to get a humidifier next to my bed. I think you may be right. So, THANK YOU.
@JRR Tokin (awesome handle btw) : Ah, lots of variables at play here. I change the water in my bubbler every morning, usually with a bottle of crystal geyser drinking water (bottled, i know i know, waste of $$$). lately I've switched to trying out my local city (san jose)'s tap water. I swear, tap water stacks about an inch higher in my bubbler. San Jose is known for its very hard water, wonder if that has something to do with it?
