Cocaine use is increasing, while the trend for MDMA is less clear. Among drivers apprehended in Norway from 2000 to 2022, cocaine was detected in 2,331 cases and MDMA in 2,569 cases. In cases where only one drug was present, 54% of drivers with cocaine and 38% with MDMA were clinically impaired. Higher blood cocaine concentrations were linked to greater impairment odds, but no such relationship was found for MDMA. Many drivers using these drugs were not assessed as impaired.
