Detoxification services are accessible for people in Lisbon who need assistance coming off of drugs, which is often very challenging when the individual has become physically and/or psychologically addicted to a drug or to alcohol. One of the reasons individuals find it challenging to quit using drugs is because of the process they have to go through to detox on their own. Many physical and psychological difficulties come with this process because the body begins to go through drug and/or alcohol withdrawal, the symptoms of which can range from flu like symptoms to severe anxiety and depression. In a professional Lisbon detoxification facility, detoxification services help the person go through this process as safely as possible and provide the needed physical and emotional assistance to get the individual through detoxification without relapsing. Detoxification services are not drug rehabilitation, but merely the initial step of a comprehensive drug treatment facility that will further address root addiction issues so that the person can achieve long term sobriety.
