Cocaine addiction and abuse has a wide range of effects on the body and brain as well as social implications. As a result, rehab for cocaine abuse is complex and requires attention to multiple problems. For cocaine rehab to succeed it must address each patient individually and address their individual needs. Behavioral intervention is often the most effective means for treating cocaine addiction. Rehab starts with helping the addict to break old habits, relationships with friends that use cocaine, and determining "triggers" that can cause a relapse into cocaine use. Very often patients that succeed with cocaine drug rehab are involved in a 12 step program and attend meetings regularly. The meetings help remind them of the power of the drug. Currently there are no medications designed for the treatment of cocaine addiction however the National Institute of Drug Abuse is working hard to find medications suitable for use as part of a cocaine rehab center. Research is even being performed to develop a kind of cocaine vaccine to eliminate the effects of the drug. Occassionally cocaine rehab centers have found success in using anti-depressants as part of a cocaine addiction treatment.
