Does anyone know of studies being done on ecigs? If so, can you provide any details? I'm especially interested on studies regarding conversion numbers from analogs to ecigs. These numbers I've seen seem to be all over the place, so that it's really hard to tell if one is getting more or less nicotine in the ecigs compared to analogs. I guess it depends on things like how much of the liquid is actually absorbed, how often one is vaping, the strength of the liquid, etc., etc. (No matter what the "conversion" numbers turn out to be, I'm not going back to analogs!) Thanks.
