NEW YORK (Reuters Health) - A new study shows that individuals who are addicted to cigarettes are at heightened risk of developing post-traumatic stress disorder after experiencing a traumatic event.

According to Dr. Karestan C. Koenen who led the study, nicotine dependence that exists prior to trauma exposure increases the risk of developing PTSD following trauma by two-fold. ...

Gawd, I hate smoking. I've only smoked for a few years, relatively, but it is a damned hard habit to give up.
Many people in the IPSG smoked. It's been noted in studies that more people suffering depression smoke than the norm. Depression saps a person of their resolve. Even if they want to quit something like smoking, it's much harder.
Usually, a person expresses their lack of resolve as not having the energy. They say that they can't do something because all the other things affecting their life -- pain, work, pressures day by day -- take the strength they need.

I wonder is there is some scale that shows how much "strength" a person has or needs?
