i searched ecig at wiki and found your right. the ecig was actually a nebulizer originally. they are used today to adminster medicine in vape form. i learned nebulizers effectively distribute everything in the liquid down to fungi, bacteria, and viruses. kind of interesting ultrasonics are also used to sterilize lab and surgical instruments. i saw a picture of my next grandchild today due to ultrasonic technology. it may be safer to burn ejuice with a coil is why we aren't using essentially nebulizers.
