I've heard this a few times from other people, and wouldn't you know it everyone of them used to be hardcore cigarette smokers. I think the tickle from inhaling particulates may be more uncomfortable for those of us who have been "knee-capping" our cilia with carbon monoxide and nicotine for long periods of time.

Anyway, I don't have this problem with my Volcano, but I've noticed that once in a blue moon when I take it apart for cleaning, the internal portions of the valve have a greenish/brown buildup of what is basically resin mixed with fine ground plant dust. So something solid is leaving the chamber, it just collects in the valve or in the bag. Never had a single issue with actually inhaling chunky bits, thankfully.

That buildup I mentioned - I combined it all into a small ball of my own vape-hash, and roasted it in a pipe with a friend awhile ago. HOLY HELL! :stoned: Not a long lasting buzz, but quite a kick.
