I'm not saying you should participate in this, but doing it independently is an excellent idea.
I would sooner allow medical experimentation by a mad scientist on my body than allow these anti-smoker organizations to get even a PEEK at my little toe.
Oh pluuuuuese! They have their hooks in us so deep now, do you actually think I would even let the ACS look at me? No way! Thank you!
I'm not a smoker, but lost a much-loved grandfather to smoking-related illness. He was deeply ashamed of his "lack of willpower", not understanding the many factors that were playing into his life-long addiction, including the fact that he'd been smoking since childhood and didn't know how to cope without cigarettes. I wish I could tell him what I've learned since his death. He didn't have to die the way he did and it broke all of our hearts to watch it happen.
I've never been addicted to nicotine, but there have been many other equally addictive attitudes and behaviors I've battled all my life. I applaud your desire to change in this way. Don't spend your whole life "just fixin' to" quit. Make up your mind and make it happen, if that's the secret wish of your heart.
