Don't really know what goes through people's minds to think that vaping it automatically makes it safe. There's plenty of evidence that nicotine by itself when vaped with substances like VG is a whole lot safer than smoking. But then again, it isn't harmful in patches or gums or inhalers either. In other words, it's not really the nicotine that causes harm and it's not the vaping that makes it safe.
Now when it comes to other chemicals, it's not true. That substance can be harmful, no matter how you get it into your body. Hey stupid, you want a fucking rush? Try some ebola or maybe some anthrax. Oh hell, just vape straight ethylene glycol for a while. See how that stuff works.
Sorry.............been drinkin' again!
