I really miss smoking, right now i am running a Kayfun Mini V3 with 0 nic NET juice, but it just doesn't feel the same, I've always loved smoking a pipe in the past, i inhaled, and loved it, but now I've came to vaping, i have tried alot of things, other than nic juices, i have an amazing pipe, an amazing high end tank, very nice tobacco liquids, but i think I'm just missing the nicotine, but my question is does nicotine have any bad effects on muscle growth?
