One one hand, some people are asking for evidence, on the other hand they post not serious links from internet, and on third hand they want to wait for scientists to make experiments. Instead of trying to be scientists or instead of waiting for scientists to make their experiments that their results will take years to come, I suggest you to not be guinea pigs, DONT oxidise your wires and vape on biocompatible materials. Its simple as that. All the rest is just to fill pages on ecf.
Can't argue with that, either keep your coils saturated and cool, or take the risk.
I've looked into Titanium quite a bit, even had a chat with a close teach of mine, the Senior Professor of Chemistry (Dr. Eric G. Holmberg who is a biochemist with several research interests. He has published many peer-reviewed articles and has been teaching for over 20 years, he's quite credible, and has an amazing broad knowledge of all things science, particularly Bio-Chemisty, so I thought he'd be the perfect guy to share the situation with. He for the most part agreed with me that (unless you have an allergy), even if you do (accidentally, because you shouldn't) dry burn the Titanium wire, and the heavy oxide makes it out of your juice, past the wick, and into your lungs, it won't cause noticeable harm. ESPECIALLY at the extremely tiny amounts of Titanium wire being used, and he was confident in this fact. He said, "If you were to grind up the 8 inches of wire, then completely oxidize it, then directly inhale it, you might feel some irritation, but no carcinogenic or bio-harmful effects will be present. (Unless of course, there's another element besides Titanium in the alloy.)
I really respect that your wanting to play it safe Imeo, because yes it hasn't been tested on humans, life throws alot of variables at us. I completely agree that you should be overkill in the safety aspect because, Why risk it? If you don't have to dry burn, don't. If you can't live without dry-burning don't use it. I'm sure soon this will be vaped along side kanthal, and the sheer lack of health problems resulting will be the best convincing factor for people. I'm personally super excited to try this stuff, I plan on spacing my coils so I don't have to heat and adjust, getting some relatively thicker wire, and take advantage of that surface area! Something tells me from the videos I've seen that this will be a cloud chasing machine! If I start feeling off, I'LL SIMPLY STOP! Easy as that!
I really think this "debate" is getting a little excessive, we're not talking about a world crisis, or a political event here. If you don't trust Titanium, simply wait and let me test it out for you. I'm confident enough in my scientific understanding of it, that I'm not going to die of AIDS a week after I vape it

The SAME SITUATION HAPPENED WITH
GPLAT lol. Everybody was worried about the oh-so-deadly
manganese content, and I told everyone after some research, that due to the properties of manganese, and the amount in the kanthal, it was impossible for their to be a dangerous amount in an entire 25 foot spool of Gplat. Manganese wouldn't make a good coil if it were in significant amounts to be harmful to vapers, it would break easily, and not conduct very well either. It also has a VERY high temperature threshold that would not likely be met even with a high powered box mod for it to even be released. On top of those facts, you need to inhale ALOT of manganese over A LONG period of time. I found this out through "permissible" levels of manganese allowed for welding standards. In other words how much was allowed for welders to inhale all day, at RIDICULOUS amounts relative to an 8 wrap dual coil at 50 watts. There was just no way, even if you combusted an entire spool of it below your nostrils everyday, could it harm your average (even no common sense) vaper.
Then Gplat confirmed it, there was less than 1% of the permissible amount of manganese present in Gplat period. That means even less of that 1% actually made it to your body, because it need to be heated to extreme vaping temps to even be released, and once released it need to avoid being trapped in the juice/wick, and then whatevers left of that tiny 1% will make it's way into your body. It's so negligible it's not even funny.
I really think everyone should just relax until it's found out for sure what risk there is, if any. ECF isn't about choosing wire "sides", we should all be hoping that Titanium works and is harmless because it's another coil alternative to get people off cigarettes. I personally have no strong feelings for any "side" of these "coil wars?", I'll simply vape it if there's no obvious threat, pay attention to my health as I always do, and use my brain to decide whether it's good or not. Simple as that.
I doubt Kanthal or Nichrome will ever disappear, so why the feather ruffling?
One love.
