Addiction requires it. Yup, the focus of their day is that next high or maintaining one. It's pretty simple.
Problem is besides the substance it becomes a way of life with the same circle of friends who think alike. Also many long term addicts get so used to actiing, lying and manipulating with regularity that's a habit they wind up keeping even with the substance is out of the picture. This is why it's important not just to get off the substance put some positive new things in one's life. With some it's religion, a new career and/or purpose.
