Speaking of addictions, there was a time in my life that I was addicted to marijuana. I have no regrets as to the addictions and habits of my past, but now that pot is legal in my state, I find that many people are drawn towards this high that probably never were enticed before.
Im not sure if pot addiction changes the brain dramatically or not, but I recall that it was impossible for me to quit for the longest time.
Of course, I may have subconsciously not wanted to quit...which is, in essence, step one.
Chance as a real force is a myth. It has no basis in reality and no place in scientific inquiry. For science and philosophy to continue to advance in knowledge, chance must be demythologized once and for all. RC Sproul "A lie can travel half way around the world while the truth is putting on its shoes." Mark Twain " ~"If that's not sufficient for you go soak your head."~Faith "as long as chance rules, God is an anachronism."~Arthur Koestler
