DUI/DWI offenders are often required to attend a certain number of hours either in counseling, meetings or a substance abuse treatment program. Each state has its own requirements when it comes to sentencing for the DUI/DWI offender. Offenders who are deemed low to moderate DUI/DWI offenders will typically engage in some form of group counseling or therapy. These group meetings are often held by a professional in the field of addiction recovery or a person with long-term sobriety involved in the Alcoholics or Narcotics Anonymous groups. DUI/DWI offenders deemed to be serious offenders will likely have to serve jail time at a minimum before beginning their mandatory counseling or substance abuse rehabilitation program.
