Thanks. There are a lot of people who use variants of the "anything is better than smoking" argument and then stop reasoning. I don't even believe THAT. Smoking only kills a percentage of smokers, and there are toxicities that can be worse. It's safest not inhale anything. But if we love vaping, it makes sense to look for the safest vape that we can enjoy.
I sure feel much better with no PG in my juice, and I can't see any reason to use it. It was in the first Chinese juices but i find that most people are pleasantly surprised if they give VG-only a fair try. It only takes a few drops of water and alcohol per 10 ml to thin, and temp takes care of the rest.
The flavoring picture is that there are thousands of compounds used in flavoring that the industry considers potentially toxic by inhalation. Diacetyl and related diketones were a general wake-up warning, as well as a specific flavor type to avoid. If we can't vape unflavored, fine, but it doesn't make sense to demand extreme candy counter flavoring levels. With diacetyl, for instance, the damage to animals is fatal at 300 ppm, but not even noticeable at 1/5 that level. It's a powerful argument against the "what the heck it's all better than smoking" line. Flavoring at 5% and 25% do not present the same level of risk. It's common sense to keep flavoring to a minimum.
Nicotine does not appear to be the demon toxin it's often made out to be. In some ways it's even looking beneficial. But there are potential breakdown products of nicotine that are dangerous, like nitrosamines. So, again, if 8 Mg/ml nicotine works for you most of the time, why not try 6, and keep some strong juice on hand for when you need it?
Yes, it's in large measure all about not smoking. But let's be honest, once over the hump, vaping is its own pleasure/vice/addiction. I love it. I think it's BETTER than smoking. So I think it's worth aiming to make it as safe as possible, and thankfully we have choices.
