I think this comes back to the old expression that The dose makes the poison (or: "All things are poison and nothing is without poison; only the dose makes a thing not a poison"). So, the idea that vaporizing a small amount of nicotine daily may be beneficial for certain conditions, does not contradict the idea that sucking down 20-30 unfiltered cigarettes a day is probably a net harm in all cases. Science understands this already. Government and society, not so much. Even serious research is pretty much banned with certain substances, which seems ridiculous to me.
