Residential long-term treatment in Oregon is according to statistics the most optimal rehabilitation 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 rehabilitation a true oasis. In residential long-term treatment the client can participate in rehabilitation activities in a safe and distraction free facility where there is virtually nothing that could possibly cut across their sobriety or development while in drug rehabilitation. The long-term aspect is essentially what will ensure the individual is reassured and secure enough to be able to continue to remain drug free when they leave drug rehab in Oregon, due to the fact that four weeks is very often simply not enough time in alcohol and drug rehab for the most severely addicted individuals. It can take several weeks to achieve the confidence that one can stay drug free, with a significant and intense length of time spent in rehab in a residential program.
