I was reading some articles that were saying ecigs were dangerous. They brought forth the same old bull.... argument about eg and the fda report and all that but there was some mention that I had not seen before about a chemical called tetramethylpyrazine and that it caused brain damage or bleeding. I am sorry if this has been posted before but I have truly been searching for this everywhere. Can't find anything about it through the search function here on the forum and when I google it, all I can find is that it is apparantly a old chinese folk medicine and that research shows it has beneficial effects on the spines of guinie pigs and rabbits or something like that. No matter how hard I look I can't find anything about it being dangerous to humans. You guys know anything about this chemical and wether it could be dangerous? I checked out the vendor site where I buy my eliquid and they seem to use it for many flavourings, so it is a little worrying. Anyway hope I'm not scaring anyone.
