I quit smoking/vaping last year after 22 years of that. Vaping helped my lungs, to a certain extent, because I started having so many other issues from vaping, I switched back to cigarettes before quitting for good. I quit using Defumoxan, which is a brand name for generic pills with Cytisine as active substance. I’ve been recommending it to anyone wanting to take back their life from nicotine addiction. At least where I live, you can get it without prescription.
