In any free society or free market, there are always alternative solutions. These solutions are offered and the people choose which one suits them best. In politics, this practice is exemplified by elections of representatives that share your opinions or ideals. In the market, you can choose which car, clothes, food etc. that satisfy whatever your needs are.
In terms of smoking, countless options other than e-cigs have been made available. There are the precription and OTC methods, councelors, therapists, hypnotists, magnetic ear rings, bracelets, music.... entire industries and practices revolve around the people's desire to change their habits. There are also the supporters of these industries and practices. But at least try and fight with facts instead of conjecture, baseless ridicule, or flat out falsehoods.
The free market of ideas and products have produced victories on both sides. E-cigs help some people quit. So have other methods. What seems difficult to understand is why one singular new method gets positively demonized without remorse on a repeated basis. I have yet to see any news articles blasting away at the fringe wacko methods for quitting like the ear magnet or the laser therapy. I haven't seen the FDA raising much trouble with companies that market these and similar products or services. Many of these methods are no better than snake-oil salesmen. The FDA seem willing to disregard e-cig successes and applaud products with a miserably low success rate.
The free market allows those, whose products or services succeed, to rise and prosper. Those ideas that fail, diminish. Take a hint from those who have or are succeeding. Research and develop solutions that are similar, instead of trying to reinforce a failed idea.
My father always said, "Raise others up to your level and never let anyone tear you down to theirs." Sound advice.
