Always good to have a better understanding of addiction and one that covers the latest research in neuroscience including the best treatment options . I find addiction an interesting topic and think that as clinicians we often pass judgement too easily with these people as they are often serial offenders and with self inflicting behaviours one can understand why as frontline medical providers we can often get frustrated and treat them accordingly. I did not learn a whole lot from this but what I did was well worth it as it did change my paradigm in this regard.

Very interesting presentation by an engaging practitioner who obviously knew his subject and had a great ability to impart the knowledge in a way most professionals could understand.
