I had a dental check up this morning, and told my dentist about my e-cig. i was a little worried that he'd be negative ...but he was really interested. "do you have to be monitored?" no. "do you have to have a prescription" no. He was interested enough that not only did he take breaks in cleaning my teeth so that i could answer intelligibly (instead of "garble internet garble") but he also took a V4L card and the forum address for a patient he has later today. woo hoo!
