title: [Addiction].
abstract: The 2009 news in medicine regarding dependence confirm the bio-psycho-social field of addiction medicine and psychiatry. First a statement is made about the risk of cardiac arythmy in opioid substitution treatments. Then a review of the treatment of C hepatitis shows its importance in an addicted population. In the field of cognitive neuroscience, progress has been made in the knowledge of "craving" and of its endophenotypical components. Electronic medias related disorders are on the border of addiction: a case study is exploring this new domain. At last, recent datas are presented on the relationship between cannabis and psychosis.
