Welcome to the ECF, Ryan! I can tell you from personal experience that vaping is much healthier for you than smoking. Smoked 1 - 1 1/2 PAD for 42+ years. Had my last cigarette in Jan. 2014.
Was diagnosed with beginning stage of COPD about 15 years ago, but still couldn't quit smoking. I've always done anything I wanted to without any breathing problems, and never required any meds for it. So I'm one of the lucky ones in that regard!
Doc said on my most recent check-up in March...that my lungs & deep breathing "sound absolutely clear". Said it's the best they've sounded for many years! I haven't changed anything that could account for that except...quitting smoking! I also got the news on my last DEXA Scan (bone density test) about a month ago, that I no longer have osteoporosis that I was diagnosed with probably 14-15 years ago. Cigarette smoking literally keeps calcium from being absorbed as much as it should be, to keep your bone density high. (This is more noted in women, but men can get it as well.) Again...my results were a direct benefit/improvement because I quit smoking! Doc even gives me a "thumbs up" when I tell him I'll never have another smoke, since my last one on Jan. 14, 2014, and that I've continued to vape instead.
Another thing that may be quite different from many people's experience - I'm taking part in a 4-year long, 3.6 million $ e-cigarette study being conducted by Moffitt Cancer Center in Tampa, FL. During that study, members are not only allowed to vape anywhere in the Tobacco Cessation building where the study is being conducted, but are also required to vape to take part in certain parts of the study. So...if a well-known, highly-respected medical institution allows vaping in its building, has vaping as a part of its study, and has doctors also present and exposed to the vapor while people are vaping...personally, I'm considering it safe to do!
So, I'd say to "go for it"! I vape as much as I want, as often as I want, and have since Nov. 2013 when I started switching to vaping and getting off the smokes. I've had nothing but positive results because of it so far!
