You know, one of the things that teens are all about is control....exercising their autonomy and separating from us psychologically. But control is important to them. So I always try to emphasize the loss of control a person experiences when using drugs and alcohol. They are no longer in control of themselves or their surroundings when impaired. And finally, the loss of control does extend in some cases to lifelong dependence on drugs or alcohol...the ultimate loss of control.
