 The driving principle behind ORT is the program's capacity to facilitate a resumption of stability in the user's life, while they experience reduced symptoms of withdrawal symptoms and less intense drug cravings; however, a strong euphoric effect is not experienced as a result of the treatment drug.In some countries (not the US, UK, Canada, or Australia), regulations enforce a limited time period for people on ORT programs that conclude when a stable economic and psychosocial situation is achieved.
