Like much of life a great part of our safety is dependent on the honesty of those we deal with. The main ingredients in vapor are PG, VG, and nicotine. PG and VG are both widely used in food products and have been studied in the past for inhalation for various other reasons. They have always been found to be safe. There has never been a long term inhalation study, and maybe the FDA should spend their time actually doing one.
Nicotine is, well, nicotine. The effects are fairly well known. Nicotine causes blood vessels to contract and raises pulse rate. At higher levels it's a very potent poison. Interestingly, nicotine alone has never been studied over very long terms either. It was always studied in conjunction with smoking. Some studies were conducted for the gum, patch and inhaler, but even those studies were mostly 1 year long even though many many people use these products far longer.
The real hazard in e-cigs, I believe, come from potential manufacturing errors in the juice. These can happen. They happen all the time with all kinds of products. They happen with or without regulation. If you look at history regulation by the FDA does not create a safer product. The FDA simply reports when Tylenol kills people, they don't prevent it.
Sadly, the only reason the FDA considers e-cigs a drug delivery device is that too many of the other chemicals have been removed. If e-cig carts had ground up tobacco crud in them, they would be a tobacco product and perfectly fine
