This study tested the hypothesis whether over-the-counter benzodiazepine availability influenced patterns of benzodiazepine use, abuse, and dependence in Chile.
If over-the-counter availability represents a major risk factor leading to benzodiazepine substance use disorders, rates of abuse, and dependence would be significantly higher among over-the-counter benzodiazepine users than among prescription drug users.
The study was a household survey of a stratified sample (N=1,500) of the Santiago (Chile) population performed by trained interviewers.
Data were collected by structured questionnaires on demographic characteristics, drug use, psychoactive substance use disorders, and other psychosocial variables.
Past-year prevalence of benzodiazepine use was 31.4%, daily use of benzodiazepines for =12 months, 5.9%, and subjects who met DSM-III-R criteria for dependence, 3.3%. Seventy-four percent of subjects obtained the benzodiazepine over-the-counter (always 45% ; sometimes 29%). No subject acknowledged recreational benzodiazepine use or met criteria for benzodiazepine abuse.
Use, long-term use, and dependence occurred equally frequently among both over-the-counter and prescription benzodiazepine users.
Results suggest that although over-the-counter availability increases benzodiazepine use, it is not a major risk factor that leads to benzodiazepine abuse and/or dependence.
