I am watching ngeo tv ....the drugs inc show. I just saw this researcher put drug users----cocaine in this case----- in a pet scanner. They showed them pictures with drug related associations....and the dopamine receptors rose in the behavior areas. She said they become addicted to the lifestyle in a sense so even with sincere resolve to stop and when doing well this is why the impulse is too hard to resist if put back in familiar settings. We know this, hear it and see loved ones suffer relapse but I had never seen a scientific "disease" type of reason. So much we don't know. I wonder how that could impact treatment beyond saying change your whole life.....if there would be medications to help reduce that surge? Anyway I know drug abuse affects many of our family and friends but I don't have a difficult child with the issue, just care about you all. I hope you don't mind my share. I just thought it was interesting.
