A number of free drug rehab centers are located in Idaho - facilities that provide food, shelter and addiction treatment for individuals in need. Rescue missions, the Salvation Army and state-sponsored programs for substance abuse and drug rehab offer the needed assistance in some of Idaho's top cities, including Boise, Nampa and Meridian. Free programs target applicants for addiction treatment who are homeless or who make lower incomes. While the residences may not be as private as other drug rehab facilities, they still provide all the resources needed to meet the goal of a healthy and productive life.
