I am no medical professional but I have common sense. You could never convince me it isn't a "healthier" alternative. Their has been some really good studies showing nic can help prevent Alzheimer's so I'm thinking of upping mine. Everything I've read says nic is no more harmful than caffeine. I'm not giving up either one any time soon. So just do what makes you happy everyday because we don't now what tomorrow will bring. Enjoy.
