Long-term rehabs which offer rehab for 30 days are more provide an intensely therapeutic environment for client's whose needs call for this, as is the case with a lot of people who have a significant track record of drug abuse. It's the consensus among rehabilitation experts, and experience has shown, that individuals with significant drug and alcohol use histories have much higher long-term success rates when the treatment length is 30 days or more. Even more substantial benefits are evident for those clients who continue in long-term residential rehab for three months or longer. The extensive treatment plans set up at long-term residential rehabs may be more time consuming for treatment specialists and the client, but anything less has been shown to be inadequate. This really is primarily because anything less than 30 days is barely likely to scratch the surface of any substance abuse issue that could plague the person after they depart treatment. To become physically stable may take several days or even a couple of weeks, but a significant amount of time afterwards is necessary to handle the environmental, emotional, and mental areas of their addiction which may cause a relapse once they leave a drug treatment program.
