Barbiturates are depressant drugs that can induce sleep and relieve tension. When taken in small doses, they cause decreased responsiveness and loss of muscle coordination. Higher doses between half and one dose will make a person feel sedated or "high", while one dose will make them sleep. Five times the normal dose can cause coma and 10 doses can potentially be lethal. The Comprehensive Dangerous Drug Act of 2002 defined drug users as victims and allowed for rehabilitation instead of punishment in an effort to help them live productively without drugs.
