Much of what we believe about the biopsychology of drug addiction is based on the study of drug self-administration in laboratory animals, but there is a major concern:

Habit 1: be proactive  habit 2: begin with the end in mind  habit 3: put first things first  habit 4: think win-win  habit 5: seek first to understand, then to be understood  habit 6: synergize  habit 7: sharpen the saw 

Do you have a picture for this question?
