Background Cocaine use has been associated with traffic road accident involvement. Early studies showed frequent accident involvement of patients in treatment for Substance Use Disorders. The aim of the study is to analyse the history of accidents and risk behaviours in cocaine dependent patients (CD) and other substance type dependent patients (OD).

Methods 182 patients in treatment for their Substance Use Disorders from January 2014 to September 2015 were included in the study. History of accident involvement of any kind and risk behaviours was recorded, as well as follow up to 1 year. SPSS (23) was used for statistical analysis.

Results 45.2% of patients were CD and 54.8% were OD (35.6% alcohol, 8.3%, cannabis, 5.8% opioid and 5.1% other drugs). 30.3% were women and 69.7% were men, aged 43.7 (mean) years (SD = 13). 65.6% were currently driving. Lifetime involvement in accidents was frequently reported by Substance Use Disorder patients (34.6%), more likely among CD (40.4%) than among OD (29.0%). Furthermore, CD patients referred further potentially dangerous activities, such as driving under the influence of drugs (65.9% vs. 33.3%) and driving with abstinence symptomatology (41.7% vs 12%), more frequently than OD patients.

Conclusions Substance Use Disorder patients frequently drive and were frequently involved in accidents. Accident involvement and risk behaviours were more likely among cocaine dependent patients than those dependent on other drugs.
