Alcohol and drug abuse are major areas of concern for many American Indian/Alaska Native communities. Research on these problems has often been less than successful, in part because many researchers are not sensitive to the culture and traditions of the tribes and communities with which they are working. They also often fail to incorporate tribal customs, traditions, and values into the interventions developed to deal with substance abuse.
