Say, 100 smokers who want to quit or cut back on smoking, and you let them try vaping. Assume they get a good setup and good juice, what would be a typical success rate? Say, x% would quit for good, y% would cut down significantly but not completely, and z% would fail completely and not like vaping at all as a substitute.
