My daughter used cocain. how long dose it take to detox?

Depends: This can be quite variable based upon the amount used and how long the individual has been using cocaine. You can find detailed information through the national institutes of health: http://www.Nlm.Nih.Gov/medlineplus/ency/article/000947.Htm.

How much/long?: It depends on how it was done. However, it should be out of her system within a couple of days. But, if she was doing it for a prolonged amount of time, she can have psychological dependency.

Short time: The symptoms of Cocaine intoxication should be gone within a few hours. Fatigue, depression and drug seeking withdrawal symptoms take longer. If your daughter was using for a while, the rehabilitation process, with a focus on rebuilding habits and relationships will be important. That is a long term process.
