Yes, I have. My Hubby has never smoked. We are both diabetic. Recently, having seen one in a B&M we visited, he expressed interest in an epipe. I'm neither encouraging nor discouraging him but am tellling him that as long as he uses it like a pipe (IE, doesn't inhale) and vapes only zero nic then I don't see a problem if that's something he wants to do. The first on his juice list will be my cheese cake juice but I can't let him try it first as it contains nic.
