[Addictions : what's new in 2025].

The field of addiction medicine is rapidly evolving due to shifting drug markets and emerging patterns of use. In Switzerland, the possible arrival of highly potent synthetic opioids highlights the need for interprofessional preparedness, particularly through wider training in naloxone use. At the same time, the rise in recreational ketamine use brings an underestimated urological complication: ketamine-induced cystitis, whose early detection is crucial. Growing digitalisation also fosters compulsive pornography use, where craving plays a key role; new tools such as the PCE-S scale help to better assess these mechanisms. Together, these trends call for strengthened monitoring, prevention, and adaptive clinical strategies.
