Funny

I also vape 0 nicotine, but I'm trying to wind down flavor too. Back in the early days of vaping, it was more often than not the flavoring that was causing a lot of health problems. I remember specifically that some cinnamon, grape, and butter flavors would cause popcorn lung. They've since been removed, but pretty scary nonetheless. I still avoid those flavors as a rule of thumb.

If I do have to order flavoring, I go through a site that provides all the MSDS chemical documentation for each flavor. Even then, these "safe" flavors still have skin irritation warnings. Not to mention if you sweeten your juices or buy sweet juices, its more than likely using sucralose, which in high intakes can also promote cancer. I've dived pretty deep into this because I've been making my own ejuice for nearly 8 years. Hell, I still have 5 gallons of 100mg nicotine I'm not using in my freezer (bought just before it was illegal to sell nicotine online).

The tube is interesting though, because this same site sells purely natural flavorings. Could be a nice alternative for vaping addicts. I still avoid disposables like the plague. I've tried one and the amount of flavoring and sucralose you need to achieve that flavor is more unhealthy than the extremely high nicotine. If they make someone who's been vaping for 11 years sick to the stomach, you can bet they are the worst you can get for vapes.
