How long on average, does it take someone to break a crack cocaine addiction in rehabilitation?

As long as it takes: There is not a magic number, every individual can be different, different level of motivation and willingness. They may have other psychological problems as well that need to be addressed. Have they had multiple relapses in the past. Are they willing to follow the recommended treatment plan regardless of time recommended. No treatment works unless at some point the person accepts it.

It Depends: It depends on many factors, like how long the person used the crack, how often, how much each time and if there's a family history. Also, the support system at home plays an important role. It would be , for example, nearly impossible to quit it one's spouse also used. Attending support group meetings is beneficial. One usually gets out of treatment, what one puts into treatment.
