I believe that addiction is caused by two factors.
1. A genetic pre-disposition to a more sensitive Limbic system ( the fight / flight
centre of our brain)
2. Trauma to our Limbic system in childhood.
The second point happens in lots ( if not all, children) but only those with an extremely
sensitive limbic brain will use substances and processes to medicate the distress.
Resulting in what we call addiction.
Treatment for addiction has four components.
An assessment, Abstinence, Treatment of the presenting problem, Treatment of the
underlying causal factors and avoiding cross addiction and relapse.
I have spent many years dealing with all the above .
