Can anyone find anything general about this topic? It seems 'dry' out there with research, there either isn't much or what there is is specific and so not possible to apply generally (e.g. this thing with some cinnamon flavour compromising the immune system... but really? I eat cinnamon, not inhale it...) - I don't know how they can even do research with flavours, since there's so many and people will inevitably do many. I'm more interested in a raw vape, with buds and no liquids...
Lumping vapes with smoking is useless when the latter is so much more obviously damaging, but I don't suppose even vape is totally non-irritant, as the quantity inhaled can also induce coughing, but does that mean a low temperature and smaller quantities are safe? And even then, what are its effects on cytokines?
