I do.  The one of the reasons addiction is increasing is because it has now being described as a  medical problem.  There is however no pathology involved with addiction, it is not like a disease such as cancer or diabetes.  When someone uses these drugs,  over time, the natural serotonin release is halted or stalled, and the user therefore needs more and more of the drug to create the desired effect.  "Addictive personalities" are somewhat of a misnomer, almost all of us have the capability to become addicted to narcotics.  Why some do and some do not become addicted is still not known, but in the meantime calling addictions simply a disease is disempowering to those that are addicted.  Extensive therapy is needed, replacing destructive behaviours with Healthy behaviours is imperative.  Personal accountability is important.  It is this "disease" attitude that has increased addictions, and the criminal element that fuels it.   But, the solution is not to legalize "recreational" drugs
