Abstract
BACKGROUND: Psychoactive prescription drugs are known to have abuse potential. This study was aimed at studying the non-medical use of prescription drugs (NMUPD) among individuals with prescriptions for anxiolytics, sedatives, or strong analgesics. We examined the association of socio-demographics, binge drinking, the number of drug prescriptions, and drug types prescribed for medical purposes with NMUPD among the general Finnish population. METHODS: Data were derived from population-based (ages 15-69 years) Drug Surveys conducted in Finland in 2006, 2010, and 2014. The response rates varied between 48% and 55%. Individuals with prescriptions for one or more prescription drugs in the last 12 months were included (n = 1,602) and divided into three groups: medical use only, NMUPD, and NMUPD with illicit drug use (ILLICIT USE). Multinomial logistic regression was used. RESULTS: Among individuals with a prescription for at least one prescription drug, 5.7% reported NMUPD. Living alone and being outside the labour force were associated with NMUPD. Younger age, living in a large city, living alone, and unemployment were associated with ILLICIT USE. Frequent binge drinking and a high number of drug prescriptions were associated with both NMUPD and ILLICIT USE. Those reporting ILLICIT USE were more likely to have a prescription for sedatives. CONCLUSIONS: Although NMUPD is on a rather low level among those who have a prescription for legitimate purposes, having multiple prescriptions increased the likelihood of NMUPD. Low socio-economic position and binge drinking are associated with NMUPD and this should be taken into account when planning interventions and preventive actions.
