In the science of addiction what people have found is that if you change your environment you can literally get rid of any addiction. The studies from this are from Vietnam. Experts were expecting an unprecedented heroin epidemic from veterans returning from the Vietnam war as drug use among soldiers was rampant. Turned out these soldiers came back and were no longer addicted. Scientists are guessing the causal factor for the loss of addiction was a "change in environment." It is literally the same thing that happened to the European person who replied to your post. Your brain hard wires dependencies to certain drugs but when you change your environment it may trigger something in your brain to actually unconsciously eliminate these dependencies. This makes evolutionary sense. No doubt about it, people think that the above description means that the addiction is some sort of conscious decision. It is not the case. Addition is real, but the tricks to get out of addiction may be simpler then most people think. So the question to ask is, when you quit tobacco, were you in the process of moving? Were there big changes going on in your life that would change the environment around you?
