Long-term rehabs which provide treatment for 30 days are more offer an intensely therapeutic environment for client's whose needs require this, as may be the case with most those that have a significant track record of substance abuse. It is the general consensus among rehabilitation experts, and time has shown, that individuals with significant substance abuse histories have much higher long-term success rates in the event the rehabilitation length is 30 days or more. Even more significant benefits are evident for all those clients who stay in long-term residential rehab for ninety days or longer. The extensive rehabilitation plans available at long-term residential rehabs may be more time consuming for rehab professionals as well as the client, but anything less has been shown to be inadequate. This is simply because anything under 30 days is barely going to scratch the surface of any substance abuse issue which may haunt the individual once they depart treatment. Just becoming physically stable will take several days or perhaps a couple weeks, but a significant amount of time after this is required to handle the environmental, emotional, and psychological aspects of their addiction which could cause a relapse whenever they leave a drug and alcohol rehabilitation center.
