Residential long-term treatment in Finland is when measured by statistics the most optimal rehabilitation program and method when speaking of success rates when taking into account long-term abstinence once treatment is complete. Residential long-term treatment gives the individual in rehab a recovery oasis. In residential long-term treatment the person can take part in rehab methods in a safe and distraction free facility where there is very little that could possibly cut across their success or progress while in drug rehab. 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 treatment in Finland, simply because 30 days is more often than not 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 comprehensive and intense length of time spent in rehabilitation in a residential drug rehab.
