Whether an employee has self-identified problematic substance use, or has returned a non-negative result subsequent to an ‘at suspicion’ or random drug test, a drug and alcohol assessment will assist the individual and the organisation with providing a clear process for the employees’ recovery and return to work. Drug and alcohol assessments are designed to assess the nature and extent of an individuals’ substance use disorder, provide recommendations for treatment and provide expert opinion regarding the employees’ ability to return to work.
