This is why you are coughing and why there is not any vapor/clouds being produced. PG by itself is harsh and produces little to no vapor. Adding VG will produce vapor and will not be as harsh.
Those are made to consume wacky tobaccy, herb, weed, what ever you want to call it. We do not talk about those here.
Nic salts are nicotine that has gone through a process that removes the harshness so you can get the effects of nicotine while vaping less. Salt juice is generally used in pod mods at higher concentrations approaching 50 mg/ml.
That is when some tried to use vapes that contained THC and other chemicals. What we vape is PG, VG, nicotine, and food grade flavorings that are typically carried in PG.
As an FYI we do not smoke we vape as there is no burning of material to produce smoke. E-liquids are vaporized which produces a vapor cloud.
You could be right about PG being harsh. But when I looked up the reason why with the Brave browser AI as to why vaping makes you cough, it said that it was the nicotine that caused that. It didn't mention PG as being the culprit. Of course I could have skipped the AI and looked over what was listed on the internet myself. But the AI does that a lot better and faster than I could.
Next, I am fairly new to vaping. The only reason why I did so at all is because when I go on my main main shopping trip once a month, I have my brother give me a ride. And he doesn't like me smoking in his car. But vaping is ok. So I hope you won't think I am too stupid by asking, what is VG.
I also mentioned to some degree as to why I chose to get my vape juice with only PG and nicotine. A further reason why is that about 4 years ago they had something going around the news about vaping. It spoke of some younger people who were actually getting lung damage from vaping. That is because one of the chemicals they used turned into something harmful when it was vaporized. Which was an unexpected consequence. If there is anything else that can be added to vape juice that on the surface seems safe, but when turned into vapor turns into something harmful, I want to avoid that at all costs. I take it that "VG" isn't one of those. Or I doubt if you would have suggested it. But when it comes to making you cough, when it is you vs AI, you were apparently wrong about the answer. Maybe you would be equally wrong concerning any possible harmful effects of "VG."
