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."
