Phone access in rehab is commonly authorized at some stage in therapy, though typically it is forbidden in the initial seven to ten days while the patient goes through withdrawals. The patient also needs a chance to acclimate to the treatment program, and this can best be attained without any distractions such as telephone accessibility.
Another concern is contact with detrimental influences or the patient fueling already damaged relationships by interacting before they have done adequate self-evaluation and restorative healing. It is best for the individual that contact be put off until the patient is in a more suitable place physically, mentally and emotionally.
Restricting phone access is not a penalty or even attempt to imprison and separate patients. It is just about helping the patient to achieve the greatest chance of recovery. One problem with telephone access and contact with the external world may be patients finding techniques for getting their substance of choice snuck into the actual treatment facility. Restricting phone access up until the patient reaches a certain status in healing, helps in reducing the possibility of this taking place.
