A substance abuse counselor provides treatment to those in need of treatment whom are suffering from an addiction or are in recovery and trying to stay sober. They are an essential part of society as they provide the necessary needs for addicts. The process of becoming certified according to the U.S. Bureau Of Labor Statistics (BLS) educational requirements range from a high school diploma to a master’s degree, depending on the setting, type of work, state regulations, and level of responsibility. Workers with a high school diploma typically go through a period of on-the-job training.
