So your argument is that because e-cig users are coming from one harmful product, that we should do nothing to prevent the new product from causing undue harm, and that eventually (decades?) e-cigs will become safer because someone (who?) will eventually phase out the harmful ones?
Why not stop wasting time and lives, and prevent the harmful ones from being produced/released?
