An individual who is severely addicted to drugs or alcohol will benefit greatly by attending a hospital inpatient rehab program. These types of programs are geared towards physical health, mental health and medical stabilization. Recovering persons will have access to medication as well as medical staff around the clock. While not every drug addict needs this level of care, it is useful to those who have serious physical addiction problems to drugs or alcohol. Hospital inpatient programs often last several days to several weeks. Once the inpatient portion of their recovery is finished they may choose to enter a sober living program or transfer into an outpatient program.
