I agree with the 'wanting to quit when stoned' thing. Living like that is really just a total nightmare. When you're getting high and KNOW you shouldn't be getting high, whatever pleasure that was left in smoking is sucked out. There's no going back after that line is crossed.
In my case, I didn't know any other way to live. All I knew was getting high. Talk about misery. Fortunately, there are ways out.
