I am a new user to e-cigs and just got a bottle of juice. I filled my carts last night, went to use one today and it didnt smoke right. I pulled it out of my mouth and noticed that the juice was on the end coming out of the hole and I had some on my tongue. Just wondering if this is something I need to be concerned about? I was a heavy smoker of 2-3 packs per day and now using 18mg. Any help is appreciated!
