not worried at all....will continue to vape my favorites. The whole "popcorn lung" and "coffee lung" problems were discovered from workers in plants where the workers inhaled MASIVE amounts for 8-12 hours a day 4-6 days a week for YEARS. the small amounts I would get from the flavoring in my vape do not worry me....breathing the smog in So Cal when I spend a week visiting worries me more than my vape....and I happen to enjoy a buttered popcorn vape when watching a movie and it doesnt increase my sodium or blood lipids
I have searched for any cases of popcorn lung from consumers that bought and zapped the popcorn thus exposing themselves...I can find none....my vaping exposure would be more like consumers of the popcorn that that of workers in the plants...vape on
Off to fill a tank with coffee and cream and another with buttered popcorn
I don't know how much diacetyl those workers inhaled, but I'm sure they weren't working in a massive fog of the stuff. Most likely it was fumes. Regardless, the wikipedia page mentions the man who got it from making popcorn (probably every day) for 10 years. That would be a small exposure maybe once a day for 10 years. We vape 12+ hours a day for years.
I agree with environmental toxins being a concern, but it's not like we suck on tailpipes all day either. It's easy to think of something else that is 'worse' (we don't know how good or bad the flavorings are for our health), but you should think about
Synergism
A little bit of X toxin can be safe, and a little bit of Y toxin can be safe, but put the two together and their toxicity can increase dramatically. That's why it's not such a great idea to think 'well I inhale car exhaust, outgassing chemicals from new plastic/foam products, little bit of heavy metals and toxic chemicals from those manufacturing plants, massive amounts of heavy metals during fireworks season, sex hormones from tap water/canned foods and drinks, radioactive produce and air (especially in Cali), etc...So big deal if I breath in a few more chemicals!'
It all adds up! I completely respect everyones right to be apathetic though. We can't eliminate all toxins, everything is toxic. So I understand the 'eh it's only one more thing' or 'at least it's better than smoking' mindset. Personally, I feel like this is something I have control over, so I might as well minimize risk. Still going to use a few flavors for now, but single flavors at maybe 5% max.
Oh no..Guys help!...I'm turning into an ANTZ...I'm trying to control my life..ARrrrghhh
*Consider this though*
One chemical...one...is the reason why those peoples lungs were permanently damaged. Just my 2 pesos.
