I am currently 61 years of age and I was a heavy smoker, between 40 -50 stinkies a day. The cost was starting to be prohibitive not to mention the deterioration in my health. I was getting extremely short of breath and daily activities were becoming a problem. I used to enjoy bush walking, and squash, and I just could not participate in them any more. My doctors recommended the patches which I developed an allergy to and the oral medication be they gum or that spray made me want to throw up. A friend introduced me pen style vapes, then called the EgoII and I think they are still available, and I never looked back. At the time we were importing nicotine juice from the USA and China and it was ok. My health after a month of vaping improved dramatically and I have since progressed to mods and rebuild able tanks and have never had an issue apart from a slight PG intolerance which I corrected by now vaping 70 VG and 30 PG and that works well for me. The previous mixes being 50/50 seemed to generate a lot of phlem and wheezing but adjusting the mix to 70/30 solved my problems. I have heard of others that also have a PG intolerance and am interested in their stories.
