I couldn't agree more!  There are as many studies showing that the risk are low. I'm sure the truth lays somewhere in the middle.  I do think it's got to be better than smoking!!   Just look at the ingredients and delivery methods.

My take on it is don't take up vaping if you don't smoke. If you do smoke it seems like a much better option and might get you closer to quitting.  I really think this is true if you're an infrequent smoker.

I smoked years ago. I am really happy I quit, but I do miss smoking in certain social situations. 

I've tried vaping.  If you buy good gear it's a great substitute for smoking.  Don't let those silly little fake vape cigs you see in the drug store fool you, they suck... You don't need to spend a lot to get a decent rig.

No surprise ecig vaping probably has risks. I was rather tired when I read the study, but it seems at a low voltage, around 3.3v, there was no detectable form of that formaldehyde. The high end voltage was 5v, which most people won't use on tanks and atomizers like that. Fries them too quick at least. Usually I see folks use 3.6v-4v, which makes the risk less clear. Though people that use drippers at super high wattages (basically human fog machines), they have to be even worse off. I do think the study said it ran the vape for around 3-4 seconds, which is reasonable and common IME.

There are a lot of other details I'd like to see mentioned or studied. Is it primarily just propolyne glycol that has this risk? That and vegetable glycerine? Both together? The study made me think primarily PG, but another line confused me on that.

Also, what sort of atomizer are we dealing with? What was its impedance? Did they study different types of liquid to account for variable quality and grade levels, different PG/VG ratios, how various flavorings or lack thereof affect results, and so on?

No doubt the early results are interesting, and discouraging for vapers, but we really need more robust studies. I'm sure they will come. And like I said, I may have missed something, and I was tired when I read the study itself. Point out any errors I made if so.

for someone at 1-2cigs per day, I would say likely not worth the initial investment cost.

the small cigarette-sized e-cig w/ cartomizers have terrible performance.

you need to step up to an ego battery + a nice clearomizer tank. likely would need x2 tanks for swapping flavors. also need usb charger. e-juice and coils will need to be purchased semi-regularly. that kind of set-up is nice, but still doesn't not provide the most ideal experience. A few years back, I was able to purchase all the pieces separately for under $50 (which was cheaper than the combo/starter kits at the time). For a budget clearomizer I would recommend the Stardust V2 or Vivi Nova Tank (which are top-coil tanks, vapor will be warmer). I've been using an Aspire Nautilus tank which has been quite reliable once you get use to it but a bit more tedious to clean and reload. (bottom-coil tank).

you really need a variable voltage battery to fine-tune what kind of throat hit & vapor cloud production you like (can achieve similar effects with different resistance coils, but no on the fly switching), which will be a bit pricier.

also, ego batteries also kinda tamper out when they run low on power, so for even better performance, you want a tube-style or box-style mod that holds replaceable, rechargeable battery.

....hahah, basically, escalating hobby kinda like audio gear.

I was on half a pack a day when I swapped to ecigs try to cut back slash quit slash save money. Realistically, the convenience of being able to smoke indoors has likely skyrocketed my nicotine usage & it is unlikely I really cut back or saved much money.

I would not recommend for health reasons as well. If you are at a low cigarette count, try not to escalate or get more into smoking-related/vaping stuff. Nicotine can be quite addicting once you get used to a certain daily intake & the health issues associated are quite terrible.

Hope this was helpful & Good luck!
