It's also the case that vapes are entirely a waste of resources no matter how you cut it. There's no good reason they should exist, and so even the smallest amount of waste is still a negative. Conceptually, this is somewhat similar to spraying insecticide to protect people from Malaria (painful to spray so much poison, but there's a clear benefit) vs. a consumer spraying their back yard so they don't have to experience insects whatsoever. (no real benefit, and just as costly if done at scale)
