Models are useful tools, but at the end of the day you’re not going to get a conclusive answer to a question like “what are the impacts of vaping on human health?” without looking at a real life human. At least at current levels of scientific understanding, being able to plug a chemical into an equation and pop out a complete description of the effects (my interpretation of what the gp is asking for) is a bit of a pipe dream.
