Hospital inpatient drug and alcohol rehab for alcohol or drug addiction is often required for persons who have specific health-related issues linked to their addiction, as does sometimes occur with specific types of drug or alcohol detox or for clients whose physical or mental state has been compromised by their addiction. Hospital inpatient drug and alcohol treatment in Paris for drug and alcohol issues is often also needed for those who are plagued by co-occurring psychological illness that will require intensive rehabilitation services which may not be delivered in regular rehabilitation. Treatment clients who wish to go through a medication assisted drug detox, as is often the case with people addicted to opiates such as heroin and prescription opioids, might also opt to receive this kind of treatment in a Paris hospital inpatient drug detox program.
