Drug addiction is a major social, economic and hygienic challenge that impacts on all the community and needs serious threat. Available treatments are only successful in short-term unless underlying reasons making individuals prone to the phenomenon are not investigated. Nowadays, there are some treatment centers which have comprehensive information about addicted people. Therefore, given the huge data sources, data mining can be used to explore knowledge implicit in them; their results can be employed as knowledge-based support systems to make decisions regarding addiction prevention and treatment. We studied 471 participants in such clinics, where 86.2% were male and 13.8% were female. The study aimed to extract rules from the collected data by using association models. Results can be used by rehab clinics to give more knowledge regarding relationships between various parameters and help them for better and more effective treatments. The finding shows that there is a significant relationship between individual characteristics and LSD abuse, individual characteristics, the kind of narcotics taken, and committing crimes, family history of drug addiction and family member drug addiction
