The above seems right... all we can really say at this point is that vaping is safer than smoking. If you weren't a smoker, then that really doesn't mean too much; I would say that vaping is probably safer than drinking alcohol or driving a car in any populated area -- but that's just my opinion, not a "study" or anything like that.
But, you're an adult, and as such, you probably engage in quite a few potentially-risky activities -- cooking, breathing city air, drinking that alcohol or driving that car in a populated area; if you choose to vape for whatever reason, as an adult, you have that option, and *I* would never say that you don't have that right. But be aware that vaping *may* carry some risks; certainly the flavors, whose risks we don't yet really know or understand, since those flavors were designed for eating/drinking, not inhalation. I would also say that "extreme vaping" (cloud chasing, high wattage, low ohms, etc) is probably riskier than "tootle puffing" (using a more moderate device for a more moderate style of vaping). Those who need to go to extremes with vaping so that they can stay smoke-free, for them vaping is still probably safer than smoking, but if one is not seeking to escape a pernicious addiction, then that type of extreme vaping is probably not a very good idea.
There may also be *some* risk associated with PG/VG, though those risks seem to be very individual -- allergies, sensitivities, intolerances. Only you can decide if either of those is causing you a problem.
