It's not the nicotine that I'm worried about so much. I only use the 8mg. I like the flavor and some small vapor would be nice. But the PG dries my mouth and lips badly. I figure that the VG might do the same because of the research I've done. But I am just looking for an alternative, so that i can still do the hand to mouth action of smoking. While being able to enjoy different flavors. I could use a patch to take the edge off, but I like being able to use a cart with nicotine in it if I'm having a nic fit. Instead of wearing a patch all day. And I like having the option to use a cart without nicotine if I just want to Vape for the mental part of the addiction. That's what's tough for me, i like to smoke while talking with friends or going out to clubs. But I don't need much nicotine. When I did smoke I had about 10 ultralights per day. But I smoked for 15 years and the action of smoking is what has a hold on me.
