You know, if you don't over-think the analogy, it makes perfect
sense and I find it humorous. When I mentioned to my wife that ECF folks call smokes analogs, she got it immediately and laughed. Everyone I have mentioned it to, i.e., smokers, laugh as well. It's become a good ice-breaker, if you will, and a point of separation to explain the difference quickly to smokers, i.e., "high-tech."
