Residential long-term treatment in Rainier is statistically the most optimal treatment center and method in terms of success rates when taking into account long-term abstinence once treatment is complete. Residential long-term treatment gives the client in treatment a virtual oasis. In residential long-term treatment the individual can take part in rehabilitation activities in a positive and distraction free atmosphere where there is very little that could possibly cut across their sobriety or progress while in drug and alcohol treatment. The long-term option is essentially what will ensure the client is reassured and stable enough to be able to continue to remain drug free when they leave drug and alcohol rehab in Rainier, simply because four weeks is most often simply not enough time in alcohol and drug rehab for critically addicted clients. It can take many months to achieve the confidence that one can stay drug free, with a significant and intense length of time spent in treatment in a residential drug rehab.
